Error P0335 on Nissan Almera Classic: complete analysis of the problem with the crankshaft sensor

Error code P0335 on Nissan Almera Classic (especially on models with engines QG15DE And QG18DE) is one of the most insidious malfunctions that owners encounter. It signals problems in the circuit crankshaft position sensor (CPS), but often its true reasons lie deeper than it seems at first glance. Unlike other errors, P0335 cannot be ignored: it can lead to stopping the engine completely while driving, especially at speeds above 80 km/h.

In this article we will not just list possible reasons, but will analyze them taking into account the specifics Almera Classic (including wiring features, ECU “weak spots” and nuances of working with diagnostic equipment). You will learn how to distinguish a real sensor malfunction from false alarms, what hidden defects most often missed by service technicians, and why sometimes the error returns even after replacing the DPKV. For clarity, we provide a table of sensor compatibility, multimeter test diagrams and step-by-step instructions with photos.

What does error P0335 mean on Nissan Almera Classic

Code P0335 stands for "Crankshaft position sensor circuit malfunction". In the system OBD-II this is generic code, but Almera Classic (especially pre-restyling versions 2006–2012) it has its own characteristics:

• 🔧 Crankshaft sensor here inductive type (unlike Hall sensors on new models), which affects diagnostic methods.
• ⚡ On Almera with ECU Hitachi The error may appear sporadically due to “floating” contacts in the ECU connector.
• 📉 Most often P0335 is accompanied by power failures, jerking at idle or difficult starting "hot".
• 🚨 Critical moment: if an error occurs while driving, the ECU can put the engine into emergency mode with the speed limited to 2500–3000.

It is important to understand that P0335 is not always the fault of the sensor itself. According to service statistics, in 40% of cases the problem lies in wiring (especially at the point where the harness passes near the exhaust manifold, where the insulation melts due to temperature), and in 25% - in mechanical damage drive disc on the crankshaft (for example, chipped teeth).

Causes of P0335: From Obvious to Hidden

Let's consider all possible causes, ranking them by frequency of occurrence. Nissan Almera Classic:

Reason	Frequency (%)	Signs	Difficulty in eliminating
Damage to the sensor wiring (melting, breakage, short circuit)	45%	The error appears during vibration or after washing the engine	Average
Malfunction of the crankshaft sensor itself	30%	Constant error, engine stalls	Light
Damage to the drive disk (ring gear)	15%	Error + metallic knock during operation	Difficult
Oxidation of contacts in the ECU or sensor connector	7%	Occasional appearance of P0335	Light
ECU firmware failure (especially after chip tuning)	3%	The error appears after flashing the firmware or resetting the battery	High

Particular attention should be paid wiring. On Almera Classic The crankshaft sensor harness runs close to the exhaust manifold, where the temperature reaches 200°C. Over time, the insulation becomes brittle and the wires can short out to ground. You can check this visually or using a multimeter in dial mode.

⚠️ Attention: If P0335 appears only after rain or car wash, with a 90% probability the problem is moisture getting into the sensor connector. In this case, it is enough to clean the contacts and apply dielectric grease.

How to Diagnose P0335: Step-by-Step Instructions

It is more convenient to divide diagnostics into 3 stages: visual inspection, multimeter check and computer diagnostics. Let's start with the simplest:

1. Visual inspection

• 🔍 Take a look crankshaft sensor (located on the oil pump cover, next to the pulley). There should be no cracks or traces of oil on it.
• 🔌 Check it out sensor connector: oxidation or green coating on the contacts is a sign of moisture penetration.
• 🔥 Explore wiring from the sensor to the ECU. Inspect the area near the exhaust manifold especially carefully.

2. Check with a multimeter

To test the crankshaft sensor for Almera Classic follow these steps:

1. Remove the sensor from the engine (disconnect the connector and unscrew the bolt by 10)

2. Set the multimeter to ohmmeter mode (200 Ohm)

3. Measure the resistance between the sensor terminals (standard: 550–750 Ohm)

4. Check for absence of short circuit to the housing (resistance should tend to ∞)

-->

If the sensor resistance above 900 Ohm or below 400 ohms, it needs to be replaced. Also note inductance: for a working sensor it is 200–400 mH (checked with a special device).

3. Computer diagnostics

For in-depth diagnostics, you will need a scanner that supports the protocol Nissan Consult (For example, Launch X431 or Delphi DS150E). Please pay attention to the following parameters:

• 📊 RPM signal (engine speed). If the readings “jump” or are equal to 0 while the engine is running, the problem is in the sensor or wiring.
• 📈 Sensor voltage (should be 0.3–1.5 V at idle).
• 🔄 Synchronization errors (such as P0336 or P0340), which often accompany P0335.

⚠️ Attention: If P0335 is cleared and it returns immediately after starting the engine, this may indicate ECU malfunction or problems with the on-board power supply (for example, low voltage from the generator).

Replacing the crankshaft sensor: nuances for Almera Classic

If diagnostics confirm that the sensor is faulty, it must be replaced. On Nissan Almera Classic (2006–2013) sensors with article numbers were installed:

• 🔧 Original: 23731-4M000 or 23731-4M010 (depending on the year of manufacture).
• 🔧 Analogues: Bosch 0 261 210 115, ERA 550361, Blue Print ADS50013.

Replacement process:

1. Disconnect the negative battery terminal.
2. Press the latch and disconnect the sensor connector.
3. Unscrew the sensor mounting bolt (10mm wrench).
4. Carefully remove the sensor and clean the seat from dirt.
5. Install the new sensor, observing gap 0.5–1.5 mm between it and the ring gear.

After replacement be sure to clear errors through a diagnostic scanner. If P0335 appears again, the problem is not with the sensor.

What should I do if the error remains after replacing the sensor?

1. Check ring gear integrity on the crankshaft (sometimes the teeth wear out or break).

2. Check the wiring from the sensor to the ECU for a break or short circuit.

3. Check supply voltage on the sensor connector (should be 5 V when the ignition is on).

4. If everything is fine, the problem itself may be faulty. ECU (diagnostics on the stand is required).

Wiring problems: how to find and fix

As already mentioned, on Almera Classic The crankshaft sensor wiring is one of the most vulnerable areas. Main problems:

• 🔥 Insulation melting near the exhaust manifold (typical for cars with mileage >150 thousand km).
• 💧 Contact corrosion in the sensor connector (especially if the car was operated in regions with salty roads).
• 🔌 Open or short circuit inside the harness (often occurs at the bend near the timing cover).

To check the wiring:

1. Disconnect the sensor connector and the ECU connector (located under the driver's side panel).
2. Check the circuit for an open circuit (the resistance between the contacts should be close to 0).
3. Check for short to ground (resistance between contacts and housing should be ∞).

If a break is detected, the damaged section of the wire must be replace (twisting or soldering is not recommended - this is a temporary solution). For temperature protection, use heat-resistant corrugation or electrical tape 3M Super 33+.

Error P0335 after chip tuning: what to do

If error P0335 appears immediately after flashing the ECU, the problem lies in the incompatibility of calibrations. The point is that on Almera Classic standard ECU firmware Hitachi sensitive to changes in ignition maps And fuel supply. Incorrect settings can lead to false alarms of the crankshaft sensor.

Solutions:

• 🔄 Return stock firmware and check if the error goes away.
• 🔧 Contact your chip tuner for calibration adjustments under your sensor.
• 📊 Check error logs through diagnostic software (for example, Nissan Data Scan). If there are entries in the logs about misfires (P0300–P0304), the problem is in the firmware.

In some cases it helps reset adaptations ECU. To do this:

1. Disconnect the battery for 10–15 minutes.
2. Connect the scanner and run the command Reset ECU Adaptations.
3. Start the engine and let it idle for 5–10 minutes (the ECU will “learn” the sensor parameters again).

Frequently asked questions about error P0335 (FAQ)

Is it possible to drive with P0335?

Short term - yes, but with caution. The engine may suddenly stall, especially during hard acceleration. Driving for a long time with this error leads to re-enrichment of the fuel mixture and increased catalyst wear.

Why does the error only appear when it's hot?

This is a typical sign unstable contact in the sensor or ECU connector. When heated, the metal expands and the oxidized contacts “open.” Also the reason may be breakdown of wiring insulation as the temperature rises.

Which crankshaft sensor is better to install: original or analogue?

Original sensor (23731-4M000) more reliable, but more expensive (about 3000–4000 rubles). Among analogues, they have proven themselves well Bosch And ERA (price 800–1500 rub.). The main thing is to check the resistance before installation!

Could P0335 be caused by a bad alternator?

Yes, if the generator does not produce enough voltage (less than 13.5 V), the ECU may not correctly read the signal from the sensor. Check on-board voltage multimeter with the engine running.

What to do if an error appears after replacing the timing belt?

Most likely, when replacing the belt, it was knocked down ignition timing or the crankshaft ring gear is damaged. It is necessary to check the timing marks and the integrity of the crown.
