Owners Nissan Almera N15 (1995–2000) often encounter the problem of no spark at the spark plugs, a symptom that paralyzes the engine. The car either refuses to start at all, or “sneezes” and stalls after a few seconds. In 80% of cases, the problem lies not in the spark plugs themselves, but in the ignition circuit: from control module to high voltage wires. But how can you accurately determine the culprit and fix the problem without unnecessary expenses?

This article will help you understand the reasons for the lack of spark on Almera N15 with engines GA14DE And GA16DE, even if you have no experience in auto electrics. We'll look at it in detail:

  • 🔍 How to check spark on candles in 5 minutes (with photos and videos)
  • 🛠️ Top 3 “weak points” of the ignition system Almera N15which break down most often
  • 💰 Cost of repairs in service vs. DIY repair (comparison table)
  • ⚡ Step-by-step instructions for diagnosing sensors and ignition module

Important: if the engine Almera N15 It won't start, but the starter turns - the problem is almost always related to a lack of spark or fuel. We will focus specifically on the ignition system, since diagnosing the fuel system requires a different approach.

1. How to check for spark on Nissan Almera N15

Before disassembling half of the car, make sure that there really is no spark. For this you will need spark plug wrench And arrester (or a regular screwdriver). Verification algorithm:

  1. Unscrew all 4 spark plugs ignition Pay attention to their condition: if they are wet (filled with gasoline) or covered with black soot, this is an indirect sign of ignition problems.
  2. Insert the candle into high voltage wire and attach its metal part to the engine ground (for example, to the valve cover).
  3. Have a helper turn the starter for 2-3 seconds. If there is no spark, the problem is confirmed.

Attention! Do not hold the spark plug with your hands while checking - the voltage in the ignition system reaches 20–30 kV, which is life-threatening. Use dielectric gloves or pliers with insulated handles.

📊 How do you usually check the spark?
  • Using a spark gap
  • By eye (by engine operation)
  • Spark plug wrench and weight
  • I contact the service

If there is no spark on all candles - the culprit could be:

  • 🔋 Ignition module (the most common reason for Almera N15)
  • 📶 Crankshaft position sensor (CPS)
  • 🔌 Breakdown of high-voltage wires or ignition coils
  • 🔌 Malfunction in the module power circuit (fuse, relay, wiring)

💡

If there is a spark on only 1-2 cylinders, the problem lies in high-voltage wires or individual coils (on models with the system DIS).

2. Ignition module: how to check and replace

Ignition module on Nissan Almera N15 - the most vulnerable point in the system. It is located on the valve cover and is responsible for generating impulses for candles. Signs of its malfunction:

  • 🚗 The engine does not start, but the starter turns
  • 🔥 The spark disappears “on hot” (after warming up)
  • 💥 An error appears P0300 (multiple misfires)

To check the module you will need multimeter. Diagnostic algorithm:

  1. Remove the block from the module (snap the lock and pull it up).
  2. Check availability +12V on red wire (contact 1) with the ignition on. If there is no voltage, look for an open circuit or a faulty relay.
  3. Ring the resistance between the contacts 1–4 And 2–3 (must be 0.3–0.5 Ohm). If the resistance approaches infinity, the module has burned out.

Where to buy an ignition module for Almera N15?

Original module Nissan has an article number 22440-4M000 or 22440-4M001. Analogues: Beru (ZS193), BorgWarner (MZ100182). The average price is 3,500–5,000 rubles. Before purchasing, make sure that the new module is compatible with your ignition system (DIS or classical).

Replacing the ignition module takes 15–20 minutes:

  1. Disconnect the negative battery terminal.
  2. Remove the high-voltage wires from the module (remember their order!).
  3. Unscrew the 3 module mounting bolts (hexagon or Torx).
  4. Install the new module, connect the wires and check for spark.

3. Crankshaft position sensor (CPS): diagnostics and replacement

DPKV on Almera N15 - the second most popular culprit for lack of spark. The sensor is located on the flywheel (from the gearbox side) and transmits a signal about the crankshaft position to the ECU. If there is no signal - control unit doesn't give a command to form a spark.

Signs of DPKV malfunction:

  • 🚫 The engine does not start, but the starter turns
  • 🔄 Lights up on the dashboard Check Engine (error P0335)
  • 🔥 The spark disappears periodically (that is, it doesn’t)

To check the sensor:

  1. Remove the block from the DPKV (it is located next to the flywheel, under the thermostat).
  2. Test the resistance between the sensor contacts with a multimeter. Norm: 500–700 Ohm.
  3. Check the voltage on the block with the ignition on: on red wire there must be +5V, on black — mass.

⚠️ Attention! If the DPKV resistance is normal, but there is no signal, the problem may be flywheel ring gear. On Almera N15 Often the teeth wear out or break, which leads to loss of synchronization.

Replacing DPKV:

  1. Disconnect the power supply.
  2. Unscrew the sensor mounting bolt (key on 10).
  3. Pull out the sensor and install a new one (original article number: 23731-4M000).
  4. Check the gap between the sensor and the flywheel - it should be 0.5–1.5 mm.

4. High voltage wires and ignition coil

If the module and DPKV are working, but there is still no spark, check high voltage wires And ignition coil. On Almera N15 with the system DIS (pair-parallel ignition) the coil is built into the module, but on earlier versions it may be separate.

How to check high voltage wires:

  • 🔍 Visually: cracks, melting or traces of breakdown (dark spots).
  • 📊 Multimeter: wire resistance should be 4–10 kOhm (depending on length).
  • 💡 At night: in the dark with the engine running, you can see the spark “leak” through the wires.

Checking the ignition coil (if it is separate):

  1. Remove the center wire from the coil.
  2. Insert a known good spark plug into it and apply it to the mass.
  3. Turn the starter. If there is no spark, the coil is faulty.

element Symptoms of a problem How to check Repair cost
Ignition module No spark on all spark plugs, error P0300 Multimeter (resistance 0.3–0.5 Ohm) RUB 3,500–5,000
DPKV Engine won't start, error P0335 Resistance 500–700 Ohm, oscilloscope 800–1,500 rub.
High voltage wires Misfires, tripping at idle Visually + multimeter (4–10 kOhm) 1,200–2,500 rub. (set)
Ignition coil No spark on cylinders 1–2 Checking the spark on an unscrewed spark plug 2,000–4,000 rub.

5. Problems with wiring and fuses

If all sensors and modules are working properly, but there is still no spark, look for the problem in electrical wiring. On Almera N15 often found:

  • 🔌 Open circuit between the ignition module and the ECU (wires yellow/red And green/white).
  • 🔥 Contacts burning in the module blocks or DPKV.
  • 💥 Fuse blown (fuse #32 (10A) in the block under the hood).
  • 🔋 Relay fault (ignition relay #5 in the cabin block).

How to check wiring:

  1. Take control lamp or a multimeter in dialing mode.
  2. Check the integrity of the wires from the ignition module to the computer (connector B136 under the torpedo).
  3. Make sure that the module receives +12V (wire red/yellow) and mass (wire black).

⚠️ Attention! On Almera N15 after 1998, the ignition circuit appeared immobilizer relay (located behind the glove compartment). If it fails, the ECU blocks the spark supply. Check it by closing the contacts 87 And 30 in the relay socket.

6. Other possible reasons for lack of spark

If after all the checks there is still no spark, consider less obvious reasons:

  • 🔧 Faulty ECU. On Almera N15 control unit (ECU) may “glitch” due to corrosion on the board or burnt tracks. Check the voltage at the ECU connector (pin 16 — +12V, contact 4 — mass).
  • 🔋 Low battery. If the voltage is lower 11.5V, The ECU may not send a signal to the ignition module.
  • 🛢️ Flooded candles. If the engine has been cranked with the starter for a long time, the spark plugs may be wet from gasoline. Unscrew them, dry them and check the spark again.
  • 🔌 Oxidized contacts in the sensor or module connectors. Clean them up contact spray (For example, CRC).

ECU diagnostics:

  • Remove the cover of the fuse box in the passenger compartment (under the steering wheel).
  • Find the ECU (black block with the inscription ECU).
  • Check the voltage at the contacts 16 (+12V) And 4 (mass).
  • If there is no voltage, look for an open circuit or a malfunction of the main relay (#1 in the cabin block).

💡

If after replacing the ignition module and DPKV there is still no spark, be sure to check the computer and power circuits. On Almera N15 1999–2000 Often the transistor switch in the control unit, which is responsible for supplying the signal to the coil, fails.

7. Troubleshooting algorithm: step-by-step instructions

To avoid wasting time, follow this diagnostic procedure:

  1. Check the spark on an unscrewed spark plug (as described in the first section).
  2. Make sure the spark plugs are working properly: If they are wet or sooted, replace them.
  3. Ring the ignition module (resistance 0.3–0.5 Ohm).
  4. Check DPKV (resistance 500–700 Ohm and availability +5V on the block).
  5. Diagnose high voltage wires (resistance 4–10 kOhm).
  6. Check fuses and relays (#32 (10A) And #5).
  7. Diagnose the ECU (voltage on contacts, integrity of wiring).

If at any stage a malfunction is found, fix it and check the spark again. In 90% of cases, the problem is solved by replacing the ignition module or DPKV.

💡

On Nissan Almera N15 with engine GA16DE (1998–2000) often fails transistor module in the ECU, which controls the coil. It can be replaced separately without purchasing the entire control unit.

FAQ: Frequently asked questions about the lack of spark on Almera N15

Is it possible to drive without spark on one cylinder?

Technically possible, but highly not recommended. Lack of spark on one cylinder leads to:

  • 🔥 Increased fuel consumption (up to +30%).
  • 💨 Accelerated wear of the catalyst (unburned gasoline burns out in the outlet).
  • 🚗 Vibrations and imbalance, which harms engine mounts.

If there is no spark all cylinders - the engine will not start.

How to distinguish a malfunction of the ignition module from a problem with the DPKV?

The easiest way replace the ignition module with a known good one (you can take a used one from friends). If a spark appears, the module is at fault. If not, check the DPKV:

  • 🔍 An oscilloscope (on a working sensor the signal should be stable no gaps).
  • 📊 Multimeter (resistance 500–700 Ohm).
  • 🔄 Substitution (temporarily install another sensor).
How much does a diagnostic service cost?

Cost of diagnosing lack of spark Almera N15 in services in Moscow and regions:

Type of work Cost (₽)
Computer diagnostics (scanner) 800–1 500
Checking the ignition module/DPKV with a multimeter 500–1 000
Checking high voltage wires 300–600
ECU diagnostics 1 500–3 000

Total cost of complex diagnostics: 2,500–5,000 rub..

Is it possible to repair the ignition module yourself?
