The engine suddenly stalls while driving, and after trying to start the car does not respond to the key - this is a classic picture of a critical failure in the engine control system. For car owners Nissan, especially models Qashqai, X-Trail And Teana, code P0335 is one of the most common and unpleasant diagnoses indicating a problem with the crankshaft position sensor.
This error blocks the supply of fuel and spark, making it impossible to start the engine until the problem is corrected. Ignoring the signal will not heal itself, but will only increase the risk of damage to other components, such as the starter or battery, due to repeated attempts to start. A careful approach to diagnostics will help save time and money by eliminating unnecessary replacements of expensive parts.
The essence of the malfunction and the role of the sensor in engine operation
Crankshaft position sensor, also known as DPKV, is the “eyes” of the electronic control unit (ECU) Nissan. It reads the position of a toothed disk mounted on a shaft and transmits this data in the form of electrical impulses. Without this information, the computer does not know what stroke the pistons are in and cannot synchronize the timing of fuel injection and spark formation.
Code P0335 means that the ECU does not receive a signal from the sensor or the signal is completely absent for a certain time. This does not necessarily indicate a breakdown of the sensor itself, although this is the most likely reason. The problem may be hidden in broken wiring, oxidation of contacts, or even mechanical damage to the ring gear.
It is important to understand that the engine management system Nissan has built-in protection: if the signal from the DPKV disappears, it instantly turns off the injectors and ignition coils. This prevents the engine from running, but makes the car immobile. Diagnostics should begin with checking the continuity of the circuit and the presence of voltage.
The main symptoms of code P0335
The behavior of the vehicle when this error occurs may vary depending on when exactly the failure occurs - during a cold start, at idle or under load. Sometimes the engine runs fine but the light comes on Check Engine, indicating an intermittent signal.
In more severe cases, you will experience a complete lack of startup. The starter turns the engine at normal speed, but the engine does not “catch.” This happens because the control unit simply does not see the moment the shaft begins to rotate and does not give the injection command.

Causes of failure in the Nissan system
List of potential culprits for the P0335 problem at Nissan quite wide, but statistics show that most often the sensor itself or its wiring is to blame. Thermal expansion, vibrations and an aggressive environment under the hood over time destroy the insulation of the wires or change the characteristics of the sensing element.
Often the problem lies in the gap between the sensor and the toothed disk. If, due to bearing wear, the crankshaft has play or if dirt has accumulated on the crown, the signal becomes unreadable. It is also impossible to exclude a defect when installing the sensor if the replacement was made recently.
In rare cases, but still occurring, the cause is a malfunction of the ECU itself or problems with the engine grounding circuit. For accurate diagnosis, you need to use a multimeter and an oscilloscope to see the real picture of the circuit.
Step-by-step diagnostic instructions
The first step is always a visual inspection. Open the hood, locate the sensor, which is usually located at the bottom of the engine near the flywheel or crankshaft pulley, and check the condition of the connector. Make sure the plug is firmly in place and that the wires do not show signs of chafing or melting.
The next step is to check the sensor resistance. Disconnect the connector and measure the resistance between the contacts with a multimeter. For most engines Nissan (HR, MR, VQ series) the nominal value is in the range from 500 to 1500 Ohms, but the exact numbers should always be checked with the service book.
If the resistance is normal, you need to check the integrity of the wiring to the control unit. This requires removing the trim and accessing the wiring harnesses. Check for breaks, short circuit to ground or positive. Often the problem lies in one broken wiring inside the braid, which is not visible to the eye.

Procedure for replacing and adjusting the sensor
If diagnostics show that the sensor is faulty, it must be replaced. On most models Nissan This is a procedure of medium complexity, but requires care. Remove the old sensor, first disconnecting the negative terminal of the battery to avoid a short circuit.
When installing a new element, maintaining clearance is critical. Many engines use a non-adjustable clearance that is ensured by a proper fit, but sometimes a spacer or shim is required. Incorrect installation will cause the new sensor to also generate an error.
After replacement, be sure to clean the connector contacts and apply dielectric grease to protect them from moisture. Connect the connector, connect the battery and clear the error codes with the scanner. Start the engine and make sure it runs smoothly and the Check Engine light is off.
⚠️ Attention: Do not use harsh chemical solvents to clean the sensor, which may damage the sensing element or the magnet inside the housing.
☑️ Replacing the DPKV sensor
Sometimes, after replacement, a “training” or adaptation procedure is required, especially if the control unit was changed or the sensor itself was non-original. In such cases, it is necessary to use a professional scanner to enter basic parameters into the ECU memory. Simply connecting the battery may not be enough for correct operation.
Correct installation of the new sensor in compliance with the factory clearance is the key to ensuring that error P0335 does not return after a week of operation.
Specifics of diagnostics on different Nissan models
Although the principle of operation of the sensor is the same for all engines, the nuances of location and electrical parameters may differ. For example, on Nissan Qashqai with the 1.6 engine (HR16DE), the sensor often fails due to overheating, as it is located very close to the exhaust manifold.
On models Teana With V6 engines of the VQ series, the problem is often related to the wiring, which over time frays at the bend near the cylinder block. Owners X-Trail with diesel engines, they may encounter contamination of the sensor with metal shavings if there are problems with gear wear.
A feature of some models is the presence of two sensors: one for synchronization (DPKV) and the other for determining phases (DPRV). Error P0335 concerns specifically the first, but is often accompanied by errors in the second, which complicates diagnosis. It is important not to confuse them when replacing them.
Technical parameters table and compatibility
To select the correct spare part, you need to know the exact parameters of your engine. Below is a table of averages for popular models, but always check your vehicle's VIN before purchasing.
| Engine model | Sensor type | Resistance (Ohm) | Signal voltage |
|---|---|---|---|
| HR16DE (Qashqai, Tiida) | Magnetic inductive | 500 – 1500 | Analog (variable) |
| MR20DE (X-Trail, Qashqai) | Magnetic inductive | 600 – 1600 | Analog (variable) |
| VQ25DE / VQ35DE (Teana, Pathfinder) | Magnetic inductive | 800 – 1800 | Analog (variable) |
| K9K (diesel, X-Trail, Almera) | Magnetic inductive | 400 – 1000 | Analog (variable) |
Please note that using non-genuine sensors with the wrong magnetic field may cause the P0335 code to appear intermittently. ECU Nissan very sensitive to signal shape and amplitude.
Why do cheap analogues often not work?
Cheap sensors often have inaccurate clearances and unstable magnets, resulting in false signals at high RPMs. The ECU interprets this as a signal loss and issues P0335.
Prevention and operating tips
To avoid reoccurrence of the error, it is recommended to regularly inspect the wiring harnesses under the hood, especially after washing the engine or during the winter. Using quality products to clean contacts and protect against moisture will help extend the life of the sensor.
Avoid heavy contamination of the engine, as oil film and dirt can change the electromagnetic properties of the sensor operating area. If you notice oil leaks in the crankcase or cylinder block area, repair them immediately.
When purchasing spare parts, give preference to original parts or proven analogue brands. Cheap Chinese sensors often fail within a few months of installation, resulting in repeated costs and wasted time.
Before replacing the sensor, be sure to clean the mounting area of any dirt or rust to ensure tight contact and proper clearance.
When to turn to professionals
If you've done all the basic checks and replaced the sensor, but the P0335 code continues to appear, the problem may be deeper. This could be a faulty ECU, damage to the crankshaft ring gear, or complex wiring problems within the harness that are difficult to access.
In such cases, a professional inspection using an oscilloscope is necessary. This device allows you to see the waveform in real time and pinpoint where the failure is occurring. Independent attempts to “ring” complex circuits without equipment often lead to erroneous conclusions.
Do not delay your visit to the service center if the engine begins to work unstably after your manipulations. Incorrect operation of the ignition and injection system can lead to overheating of the catalyst and other serious damage.
⚠️ Attention: If after replacing the sensor the error does not disappear, do not try to “flash” the ECU yourself without special skills - this may lead to complete inoperability of the car.
What to do if the sensor is working, but there is an error?
Check the integrity of the toothed disc on the crankshaft. Sometimes one or more teeth may break off due to mechanical damage or corrosion, making the signal unreadable.
FAQ: Frequently asked questions
Is it possible to get to the service center with error P0335?
No, when this error occurs the engine usually stalls or does not start at all. An attempt to tow is possible, but only on a tow truck or with the drive wheels suspended, since engine operation is impossible.
How much does it cost to replace the DPKV sensor on a Nissan?
The cost of the original sensor varies from 2000 to 5000 rubles, depending on the model. Replacement work takes from 30 minutes to 2 hours and costs an average of 1,500–3,000 rubles.
Why does the error only appear when it's hot?
This often indicates an internal break within the sensor or a wiring problem that occurs due to thermal expansion. When the engine cools down, contact is restored and the error disappears.
Is it possible to replace the sensor yourself?
Yes, if you have a basic set of tools and a multimeter. The procedure is simple, but requires care when connecting connectors and maintaining clearances.
Does P0335 affect fuel consumption?
If the engine does start (for example, with a partial signal), fuel consumption may increase significantly due to incorrect operation of the injection system. However, most often the car simply does not move.
⚠️ Attention: The P0335 error code on Nissan is critical and requires immediate attention as it renders the vehicle unusable for use.
