Diagnostic Code Encounter 0335 on the car's on-board computer Nissan Almera Classic often becomes a serious test for the owner. This indicator signals a critical malfunction in the engine management system, specifically in the crankshaft position sensor signal circuit. Without the correct operation of this device, the power unit cannot synchronize fuel supply and spark generation, which makes starting the engine impossible or extremely unstable.
Owners Nissan Almera Classic Often faced with a situation where the car simply stops starting, or stalls while driving for no apparent external reason. Understanding the nature of the error 0335 allows you to save time and money on diagnostics in service centers. In this article, we will analyze in detail the technical aspects of the sensor’s operation, the reasons for its failure, and provide step-by-step instructions for restoring the functionality of your car.
Ignoring this problem can lead to more serious consequences, as the electronics tries to compensate for the lack of signal by issuing incorrect commands to other systems. Without a signal from the crankshaft sensor, the Nissan Almera Classic engine control unit will not be able to start the engine, since it does not know the exact position of the pistons to supply a spark. Therefore, timely identification and elimination of faults is a priority for every car owner.
The essence of the problem and technical description of error 0335
Error 0335 In OBD-II terminology, it stands for "Crankshaft Position Sensor 'A' Circuit Malfunction". In context Nissan Almera Classic this means that the engine control unit (ECU) does not receive reliable data from the crankshaft position sensor (CPS) or receives a signal that does not correspond to the specified parameters. This sensor is the "eye" of the car's electronic brain, monitoring rotation speed and shaft position.
If such an error occurs, the control system goes into emergency mode or completely blocks the engine from starting. The ECU tries to determine the crankshaft position using other parameters, for example, using a phase sensor, but without the main signal, the synchronization accuracy is lost. This leads to the fact that fuel is injected at the wrong moment, and the spark jumps at the wrong time.
The key point is that the problem may not only be with the sensor itself, but also with the wiring, connectors, or even the mechanical part of the engine. Violation of the integrity of the shielding braid wires often leads to interference, which the ECU interprets as a sensor failure. Therefore, diagnostics must be comprehensive and not limited to just replacing the part.
It is important to understand that the code 0335 may appear periodically. Sometimes the car starts normally, but after a few kilometers of driving the error appears again. This indicates poor contact in the connector or overheating of the sensor's sensitive element, which loses its properties as the temperature rises.
The main causes of system failure
Reasons for the appearance of the code 0335 on Nissan Almera Classic can be divided into several categories, from the simplest to the complex. The first and most common reason is physical wear or failure of the crankshaft position sensor. Inside the device there is an inductor or Hall element, which over time loses its magnetic properties or burns out.
The second group of reasons is related to the electrical circuit. It could be wire breaks, oxidation of contacts in the connection connector or short circuit to ground. Under vehicle operating conditions, especially in winter, vibration and temperature changes contribute to the destruction of wire insulation, which leads to an unstable signal.
Mechanical factors cannot be ruled out. If the flywheel ring gear or crankshaft pulley is damaged, dirty, or misaligned, the sensor will not be able to read the marks correctly. The gap between the sensor and the gear also affects - it must be strictly regulated.
- ⚠️ Damage to wire insulation due to contact with hot engine components.
- ⚠️ Contamination of the working end of the sensor metal shavings or dirt.
- ⚠️ Malfunction of the ECU itself (rare, but possible).
Symptoms and behavior of the car in case of malfunction
Behavior Nissan Almera Classic when an error occurs 0335 may range from slight jerking to complete inability to start. The most obvious symptom is an illuminated Check Engine light on the dashboard. However, in the early stages, the problem may only appear under certain conditions, such as a hot start.
Drivers often note unstable engine operation at idle. The car may stall immediately after starting or when stopping at a traffic light. This occurs due to the fact that the control unit cannot correctly calculate the ignition timing, since the signal about the crankshaft position is lost or distorted.
Another sign is a loss of power and a sharp drop in throttle response. When trying to accelerate, the engine may choke or run rough. In some cases, the system completely blocks the fuel supply, and the engine stalls while driving, which creates an emergency situation on the highway.
It is important to note that in some cases the error 0335 may “stick” in the ECU memory even after the fault has been eliminated. This requires a forced reset of error codes through the diagnostic scanner. If the machine is working normally, but there is an error, this is a reason to check the wiring for oxidation of the contacts.
- ⚠️ Complete engine start failure (the starter turns, but the engine does not catch).
- ⚠️ Jerks and jerks when driving under load.
- ⚠️ Spontaneous stop engine running without warning.
Step-by-step instructions for diagnosing and replacing the sensor
Before proceeding with replacement, it is necessary to conduct a thorough diagnosis. Start by visually inspecting the sensor and its wiring. On Nissan Almera Classic The sensor is located on the gearbox, next to the flywheel. You will need access to the underside of the car or a lift.
First check the integrity of the connector. Disconnect it and inspect the contacts for oxidation or moisture. If the contacts are dirty, clean them with a special contact cleaner and apply new grease. Check whether the connector is firmly fixed when connected.
Next comes checking the resistance of the sensor itself. To do this, use a multimeter switched to resistance measurement mode. Connect the probes to the contacts of the sensor (not the connector, but to the terminals of the element itself). Normal resistance for standard sensor Nissan usually ranges from 500 to 1000 Ohms, but it is better to check the exact values in the technical documentation.
If the resistance is normal, check the wiring for an open. Switch the multimeter to continuity mode and check the circuit from the sensor connector to the ECU connector. Make sure there is no short to ground. If all electrical tests pass but the error persists, the problem is most likely in the sensor itself or in the gear.
☑️ Diagnostics before replacement
The process of replacing the sensor is not particularly difficult, but requires care. Unscrew the fastening bolt, carefully remove the old sensor and install the new one. When installing, pay attention to the rubber O-ring - it must be in place and not damaged.
After installing the new sensor, do not rush to start the car right away. Connect a diagnostic scanner and reset errors from the ECU memory. Then start the engine and check if the error goes away 0335. Let the car idle to ensure stable operation.
If the error returns immediately, check the gap between the sensor and the flywheel ring.
- ⚠️ Don't try too hard when screwing in the sensor, so as not to strip the thread.
- ⚠️ Check for metal shavings on the magnet of the old sensor - this is a sign of engine wear.
- ⚠️ Use only original spare parts or high-quality analogues, since cheap sensors often give false readings.
Common mistakes when replacing
Car owners often forget to check the gap between the sensor and the flywheel. If it is too large, the signal will be weak and the error will return. It is also important not to mix up the wires when connecting, although in the connector they are usually protected with keys to prevent incorrect installation.

| Original article number | 23731-ED00A | - | Check relevance by VIN |
The resistance of the sensor is a key diagnostic parameter: if it goes beyond 500-1000 Ohms, the sensor requires replacement even in the absence of external damage.
Nuances of operation and problem prevention
To avoid the error reappearing 0335, it is important to follow the operating rules and regularly carry out preventive inspections. One of the main reasons for sensor failure is overheating. Try to avoid running the engine for long periods of time under high load conditions, especially in hot weather.
Regularly clean the area around the sensor from dirt and oil. The accumulation of dirt can lead to overheating of the element or disruption of heat dissipation. If you notice that there are traces of oil on the sensor body, immediately eliminate the cause of its appearance, as oil destroys wire insulation and seals.
Use quality fuel and motor oil. Impurities in the fuel can contribute to the formation of carbon deposits on engine parts, which indirectly affects the operation of the ignition and timing systems. Clean fuel ensures more stable engine operation and reduces the load on all electronic components.
When replacing the sensor, always replace the O-ring. The old ring may lose elasticity and allow dirt or oil to enter the housing, which will lead to rapid failure of the new sensor. This is a small detail that is often ignored, but plays an important role in the longevity of the knot.
Before purchasing a new sensor, be sure to remove the old one and check for metal shavings at its end. If there are chips, this is a signal of problems with the flywheel or gearbox gears, and simply replacing the sensor will not solve the problem for a long time.
Answers to frequently asked questions from owners
Owners Nissan Almera Classic frequently asked questions related to the error 0335, especially when the diagnosis does not give a clear answer. Below are answers to the most common questions that will help you quickly understand the situation.
Is it possible to drive with error 0335?
No, driving with this error is strictly not recommended. If the car starts, it can stall at any moment, creating an emergency situation. If the car does not start, movement is impossible. The ECU can prevent the engine from starting to protect against uncontrolled fuel injection.
Why does the error only appear when the engine is hot?
This is a classic sign of a dying sensor or poor connection. When heated, materials expand and microcracks in the winding or contacts can open, interrupting the signal. After cooling, the contact is restored and the error disappears.
Do I need to reset the error after replacing the sensor?
