Error P0335 on <em>Nissan Almera Classic</em>: Complete Diagnostic and Repair Guide

Error code P0335 on Nissan Almera Classic (N16) is one of the most common problems faced by owners of this car. It indicates a fault in the circuit crankshaft position sensor (CPS), which can lead to serious consequences: from unstable engine operation to complete ignition failure. Unlike other errors, P0335 cannot be ignored - it can cause damage. ECU or even engine jamming during long-term driving with incorrect sensor signals.

In this article we will look at what exactly the error means P0335, how to correctly diagnose it (including checking with a multimeter and oscilloscope), and we will also give step-by-step instructions for eliminating it - from simply cleaning the contacts to replacing the sensor or repairing the wiring. We will pay special attention specifics of Almera Classic with engines QG15DE And QG16DE, where the location of the DPKV and its connector have their own nuances.

If your Nissan starts up poorly, stalls while driving, or gives out Check Engine with code P0335 - do not rush to change the sensor at random. In 40% of cases the problem lies in oxidized contacts, damaged wiring or even a malfunction flywheel ring gear. We will show you how to identify the true cause without unnecessary expenses.

What does error P0335 mean on Nissan Almera Classic?

Code P0335 stands for "Crankshaft position sensor circuit malfunction" (Crankshaft Position Sensor "A" Circuit Malfunction). This sensor (DPKV) is responsible for synchronizing the operation of the ignition and fuel injection systems. If ECU ceases to receive the correct signal, the engine loses its “guidelines” in the position of the pistons and valves, which leads to:

• 🔴 Misfire — the engine “troits” and jerks during acceleration.
• 🔴 Difficulty starting — the starter turns, but the engine does not catch.
• 🔴 Spontaneous stop while driving, especially at low speeds.
• 🔴 Emergency mode activation — Check Engine lights up constantly, power is limited.

On Almera Classic DPKV is located on oil filter housing (from the gearbox side) and reads the signal from flywheel ring gear. A special feature of this model is the high sensitivity of the sensor to dirt and vibration. For example, if at least one tooth is chipped on the crown, ECU will record error P0335 even if the sensor is working.

⚠️ Attention: On engines QG16DE (1.6 L) error P0335 is often accompanied by a code P0340 (phase sensor). This is due to the fact that ECU uses signals from both sensors for correct operation of the system VVL (variable valve timing). If you see both errors, check the DPKV first!

Causes of error P0335

Here is a complete list of possible causes, ranked by frequency of occurrence on Nissan Almera Classic:

Reason	Frequency (%)	Signs
Contamination or damage to the DPKV	35%	The error appears periodically, especially in wet weather
Oxidation of sensor connector contacts	25%	Problems with cold starting, error disappears after warming up
Damage to wiring (break, short circuit)	20%	The error appears during vibration (for example, on bumps)
Flywheel ring gear malfunction	15%	Knocks from the transmission, error P0335 is accompanied by P0320 (knock sensor)
ECU firmware failure	5%	The error appears after disconnecting the battery or chip tuning

In practice, the most insidious cases are when the problem floating. For example, the error appears only when there is high humidity (oxidized contacts) or after washing the engine (water gets into the connector). Also on Almera Classic There is a factory assembly defect: over time, the DPKV fastening becomes loose, and the sensor begins to “walk” relative to the crown, producing false signals.

How to Diagnose Error P0335: Step-by-Step Instructions

Before rushing to change the DPKV, carry out a complete diagnosis. Here is the algorithm that the masters use Nissan-services:

1. Read errors with scanner (For example, ELM327 or Launch CReader). If there are other codes besides P0335 (for example, P0320, P0340), this will narrow down your search.
2. Visual inspection:
   • 🔍 Check the integrity of the wiring from DPKV to ECU (often grinds near the exhaust manifold).
   • 🔍 Inspect the sensor connector for oxidation or moisture.
   • 🔍 Make sure the sensor is tightly secured (not loose).

Checking the sensor resistance: Disconnect the connector and measure the resistance between the DPKV contacts with a multimeter. Norm for Almera Classic: 550–750 Ohm.

Checking the signal with an oscilloscope: Connect to the signal wire of the sensor (usually the middle pin) and crank the starter. The screen should have a smooth sinusoid with an amplitude of at least 0.5 V.

If you don't have an oscilloscope, you can use ECU self-diagnosis mode (relevant for Almera Classic before 2006):

1. Выключите зажигание.
2. Нажмите и удерживайте педаль газа до упора.
3. Включите зажигание (не запуская двигатель).
4. Через 5 секунд начнёт мигать Check Engine — считайте количество длинных и коротких вспышек (код ошибки).
- P0335 соответствует коду 35 (3 длинные + 5 коротких вспышек).
5. Отпустите педаль — тест завершён.

⚠️ Attention: On Almera Classic with QG16DE If the DPKV signal wire breaks, the engine may start up and work, but with serious interruptions. This is due to the fallback algorithm ECU, which uses signals from the camshaft sensor. However, you cannot drive in this mode - there is a risk of damage catalyst And lambda probes!

How to fix error code P0335: from simple to complex

Depending on the cause, repairs can take from 10 minutes to several hours. Start with the simplest and cheapest methods:

1. Cleaning contacts and sensor

In 30% of cases, error P0335 disappears after simple cleaning:

• 🧹 Disconnect the DPKV connector and clean the contacts alcohol solution (do not use WD-40!).
• 🧹 Blow the connector cavity with compressed air (metal dust often accumulates there).
• 🧹 Wipe the sensor housing from oil drips (especially if the crankshaft seal is leaking).

2. Replacing the crankshaft position sensor

If the sensor is faulty (resistance is abnormal or there is no signal), it must be replaced. For Nissan Almera Classic original sensors fit:

• 🔧 Original: 23731-4M000 or 23731-4M010 (depending on the year of manufacture).
• 🔧 Analogues: Bosch 0 261 210 115, Febi 23731, Blue Print ADS30103.

The cost of the original is ~1,500–2,000 rubles, the analogue is from 800 rubles. Replacement takes 15–20 minutes:

1. Disconnect the negative terminal of the battery.
2. Disconnect the DPKV connector.
3. Unscrew the fastening bolt (the key is on 10 mm).
4. Remove the sensor and install a new one, maintaining the gap 0.5–1.5 mm to the crown.

3. Wiring repair

If the problem is in the wires, proceed as follows:

• 🔧 Find the location of the break or short circuit (often this is the area near the exhaust manifold where the wires melt from the heat).
• 🔧 Strip and solder the damaged wire, insulating it with heat shrink.
• 🔧 If the harness is severely damaged, replace it entirely (article number of the DPKV harness for Almera Classic: 24540-4M000).

4. Checking and replacing the flywheel ring gear

This is the most difficult and expensive repair. Signs of crown wear:

• 🔊 Knocking or grinding noise when cranking the starter.
• 🔊 Error P0335 appears after replacing the clutch or flywheel.
• 🔊 On the oscilloscope, the DPKV signal is “torn” or disappears in certain areas.

Replacement of the crown will require removal checkpoint and flywheel. It is better to entrust the work to specialists, as precise balancing is required. The cost of a new crown is from 3,000 ₽, labor - from 5,000 ₽.

Common repair mistakes and how to avoid them

Many owners Nissan Almera Classic make typical mistakes that only aggravate the problem. That's what can't do:

• 🚫 Ignore codes P0320 or P0340if they come with P0335. For example, a faulty knock sensor (P0320) can cause false alarms of DPKV.
• 🚫 Install the sensor without gap or skewed. Optimal clearance to the crown - 0.5–1.5 mm. If the sensor rests against the crown, it will quickly fail.
• 🚫 Use sealant to secure the connector. Over time it hardens and can damage the contacts. It is better to secure the connector with a plastic tie.
• 🚫 Reset the error without eliminating the cause. If you simply erase P0335 with a scanner, it will return after 10-20 km.

Another common problem is purchasing low-quality analogues of DPKV. Cheap sensors (for example, no-name for 300–500 rubles) often have unstable resistance and fail after 1–2 months. The best option is the original or proven brands (Bosch, Febi).

⚠️ Attention: On Almera Classic with HBO error P0335 may appear due to incorrect settings of the gas equipment. If the engine is running on gas and the sensor is configured for gasoline, ECU detects discrepancies in signals. In this case, firmware adjustment is required ECU under gas

Prevention: How to prevent P0335 from coming back

To prevent P0335 from returning, follow these guidelines:

• 🛠️ Every 10,000 km Clean the DPKV body from dirt and oil. Use carbcleaner or alcohol - they do not leave a film.
• 🛠️ Once a year check the condition of the sensor connector. At the first signs of oxidation (green coating), clean the contacts eraser or special liquid (Contact Cleaner).
• 🛠️ Avoid pressure washing the engine. A jet of water can enter the DPKV connector and cause corrosion.
• 🛠️ Monitor the oil level. When oil is overfilled, it can enter the sensor through a leaky crankshaft oil seal.
• 🛠️ When replacing the clutch or flywheel Always check the condition of the ring gear. Even small chips eventually lead to error code P0335.

If your Nissan Almera Classic If it is used in conditions of high humidity or frequent temperature changes (for example, in northern regions), it is worth additionally protecting the DPKV connector. To do this:

1. Apply to contacts dielectric grease (For example, Liqui Moly Electronic-Spray).
2. Wrap the connector electrical tape or put on heat shrink tubing.

What should I do if P0335 appears after washing the engine?

If the error occurs immediately after washing, most likely water got into the DPKV connector. Required:

1. Disconnect the connector and blow it out with compressed air.

2. Dry with a hairdryer (cold mode!) or leave the car with the hood open for 2-3 hours.

3. Check if there is any moisture remaining inside the sensor - if so, it will have to be replaced.

If the error remains after drying, check the circuit for a short circuit (with a multimeter in “continuity” mode).

FAQ: Frequently asked questions about error P0335 on Nissan Almera Classic

Is it possible to drive with P0335?

For a short time (before service) it is possible, but with caution. The engine will operate in emergency mode: loss of power, increased fuel consumption, risk of detonation. Driving for a long time with P0335 causes:

• 🔥 Overheating catalyst (due to incorrect fuel mixture).
• 🔥 Damage lambda probes.
• 🔥 Accelerated wear piston group (due to detonation).

MaximumWhat you can count on is 100–200 km of leisurely driving before repairs.

How much does it cost to diagnose P0335 in a service?

The cost depends on the region and level of service:

• 💰 Diagnostics with a scanner (reading errors) - 500–1,000 ₽.
• 💰 Full diagnostics (checking DPKV, wiring, oscilloscope) - 1,500–2,500 ₽.
• 💰 Due diligence (including removing protection, cleaning contacts) - up to 3,500 ₽.

At official dealerships Nissan the price is 30–50% higher. However for Almera Classic (the car is no longer under warranty) it is optimal to contact proven multi-brand services.

Could P0335 be caused by bad fuel?

No, direct communication There is no difference between fuel quality and P0335. However, there are indirect factors:

• ⛽ If gasoline contains metal impurities, they can settle on the sensor, interfering with its operation.
• ⛽ Detonation due to low octane fuel sometimes leads to mechanical damage ring gear (which eventually causes P0335).
• ⛽ With strong nagara in the combustion chamber (due to poor fuel), the valve timing may be disrupted, which indirectly affects the DPKV signal.

If the error appears after refueling, first check the sensor and wiring. If they are ok, drain the bad gasoline and flush the fuel system.

Which crankshaft position sensor is better to choose for Almera Classic?

Recommended options (price/quality ratio):

Manufacturer	Article	Price (₽)	Pros	Cons
Nissan (original)	23731-4M000	1 800–2 200	Guaranteed 100% compatibility, long service life	High price, many fakes
Bosch	0 261 210 115	1 200–1 500	High quality, reliable operation at low temperatures	There are defective copies (check the resistance before installation)
Febi	23731	900–1 100	Good price/quality ratio, rarely counterfeited	Service life is shorter than the original

Avoid sensors without a brand or with labels like "Made in China"without manufacturer's logo. They often have unstable resistance and fail after 5–10 thousand km.

Could P0335 be caused by a faulty ECU?

Yes, but this is an extremely rare case (less than 2% of all P0335 cases). Symptoms of a problem ECU:

• 🤖 The error appears spontaneously, for no apparent reason (sensor and wiring are ok).
• 🤖 Together with P0335 occur many other errors (for example, by temperature sensors, lambda probes).
• 🤖 ECU "freezes" - does not respond to the scanner, does not reset errors.

If you suspect ECU, check:

1. The voltage on the block (should be 12 V with the ignition on).
2. Integrity massive wires (often oxidize on the body).
3. Presence of moisture inside the unit (sign: corrosion on the board).

Repair ECU costs 3,000–8,000 rubles, a new unit costs from 15,000 rubles. Try before replacing reflash block (sometimes helps with software failures).
