Understanding the P0335 Code: A Crankshaft Position Sensor Malfunction
The P0335 code indicates a problem with your vehicle’s crankshaft position sensor (CKP). This sensor is responsible for monitoring the position and speed of the crankshaft, providing crucial information to the engine’s computer (ECU) for proper ignition timing, fuel injection, and overall engine performance. When the CKP fails or malfunctions, it can lead to various engine issues, including:
- Hard starting or engine stalling
- Rough idling or engine misfires
- Reduced engine power
- Increased fuel consumption
- Illuminated check engine light
Common Causes of a P0335 Code
Several factors can contribute to a P0335 code, including:
- Faulty Crankshaft Position Sensor: The sensor itself may have failed due to wear and tear, electrical issues, or excessive vibrations.
- Damaged or Loose Wiring: The wires connecting the CKP to the ECU may have become loose, damaged, or corroded, disrupting the signal transmission.
- Mechanical Engine Problems: In rare cases, mechanical issues within the engine, such as a faulty timing belt or a misaligned crankshaft, can also trigger a P0335 code.
Troubleshooting and Diagnostic Tests
Diagnosing a P0335 code requires a systematic approach:
- Visual Inspection: Start by visually inspecting the crankshaft position sensor and its wiring for any signs of damage or loose connections.
- Multimeter Test: Using a multimeter, you can test the sensor’s resistance and voltage to determine if it is functional.
- Diagnostic Code Reader: Connecting a diagnostic code reader to your vehicle’s OBD-II port will provide you with additional information, such as live sensor data and specific error messages.

Repairing the P0335 Code
Once you’ve identified the root cause of the P0335 code, you can proceed with the appropriate repair:
- Sensor Replacement: If the CKP has failed, it needs to be replaced with a new, compatible sensor.
- Wiring Repairs: Repair or replace damaged, loose, or corroded wires to ensure proper signal transmission.
- Mechanical Inspection: If mechanical issues are suspected, seek professional assistance from a qualified mechanic for further diagnosis and repairs.
Preventing Future P0335 Codes
While a P0335 code can be frustrating, there are steps you can take to prevent future occurrences:
- Regular Maintenance: Adhere to your vehicle’s recommended maintenance schedule, which includes regular inspections and tune-ups.
- Protective Measures: Protect the crankshaft position sensor and its wiring from excessive heat, vibrations, and moisture.
- Quality Parts: Opt for high-quality replacement parts when repairing or replacing engine components.
