OBD2 Code P0335 Nissan: Crankshaft Position Sensor Circuit Malfunction

The OBD2 code P0335 in your Nissan indicates a problem with the crankshaft position sensor (CKP) circuit. This sensor is vital for engine operation, providing information to the engine control unit (ECU) about the crankshaft’s position and speed. Understanding this code is crucial for effective troubleshooting and repair.

Understanding the P0335 Code in Nissan Vehicles

The crankshaft position sensor is a critical component of your Nissan’s engine management system. It tells the ECU precisely where the crankshaft is and how fast it’s rotating. This data is essential for determining fuel injection timing and ignition spark. When the P0335 code appears, it signifies a problem within the sensor’s circuit, not necessarily the sensor itself. This could range from wiring issues to a faulty ECU.

What Causes a P0335 Code in a Nissan?

Several factors can trigger the P0335 code in Nissan vehicles:

Damaged Wiring and Connectors: The wiring harness leading to the crankshaft position sensor can be damaged by heat, vibration, or rodents. Connectors can corrode or become loose over time.
Faulty Crankshaft Position Sensor: While the code points to the circuit, the sensor itself can be the culprit.
Damaged Timing Belt or Chain: A worn or broken timing belt/chain can disrupt the sensor’s signal.
Starting System Issues: Problems with the starter motor or its wiring can sometimes interfere with the CKP sensor circuit.
ECU Malfunction: In rare cases, the ECU itself can be faulty, misinterpreting signals or sending incorrect commands.

Symptoms of a P0335 Code

Experiencing a P0335 code can manifest in various ways:

Check Engine Light: The most obvious symptom is the illumination of the check engine light on your dashboard.
Engine Stalling or Difficulty Starting: The engine may stall intermittently or have trouble starting altogether.
Rough Idle: A rough or uneven idle can indicate a problem with the CKP sensor circuit.
Reduced Engine Performance: You might notice a decrease in engine power and acceleration.
Increased Fuel Consumption: A malfunctioning CKP sensor can lead to inefficient fuel consumption.

Diagnosing the P0335 Code

Diagnosing the P0335 code involves a systematic approach:

Retrieve the Code: Use an OBD2 scanner to confirm the P0335 code and check for any other related codes.
Visually Inspect the Wiring and Connectors: Check for any obvious damage, loose connections, or corrosion on the wiring harness and connectors leading to the CKP sensor.
Test the Sensor: Use a multimeter to test the resistance and voltage of the crankshaft position sensor. Compare the readings with the manufacturer’s specifications.
Check the Timing Belt/Chain: Inspect the timing belt or chain for wear, damage, or improper tension.
Test the ECU: If all other components check out, a diagnostic test of the ECU may be necessary.

Using an OBD2 Scanner to Diagnose P0335 Code

“A thorough inspection of the wiring and connectors is crucial when diagnosing a P0335 code,” says Michael Stevenson, a seasoned automotive technician with over 20 years of experience. “Often, the problem lies in a simple wiring issue rather than a faulty sensor.”

Fixing the P0335 Code

Depending on the diagnosis, the fix for the P0335 code can involve:

Repairing or Replacing Wiring and Connectors: Damaged wires or connectors should be repaired or replaced as needed.
Replacing the Crankshaft Position Sensor: If the sensor itself is faulty, it will need to be replaced.
Repairing or Replacing the Timing Belt/Chain: A worn or damaged timing belt/chain needs to be repaired or replaced.
Addressing Starting System Issues: Fix any problems related to the starter motor or its wiring.
Replacing or Reprogramming the ECU: In rare cases, the ECU may need to be replaced or reprogrammed.

“Don’t overlook the possibility of a damaged timing belt/chain when dealing with a P0335 code,” advises Sarah Miller, an experienced automotive engineer. “While less common, it can be a contributing factor and should be thoroughly checked.”

Conclusion: Resolving the P0335 Code in Your Nissan

The OBD2 code P0335 in your Nissan indicates a potential problem with the crankshaft position sensor circuit. Addressing this issue promptly is important for maintaining engine performance and preventing further damage. By understanding the causes, symptoms, and diagnostic procedures, you can effectively resolve the P0335 code and keep your Nissan running smoothly.
