P1336 Crank / Cam Sensor Range / Performance

The OBD2 code P1336 indicates a problem with the correlation between the crankshaft and camshaft position sensors, suggesting that their signals are out of range or not performing as expected

Definition

The OBD2 code P1336 indicates a problem with the correlation between the crankshaft and camshaft position sensors, suggesting that their signals are out of range or not performing as expected

Common causes

  • Faulty crankshaft position sensor
  • Faulty camshaft position sensor
  • Misaligned or damaged timing belt/chain
  • Wiring issues or damaged connectors
  • Faulty engine control module (ECM)
  • Incorrect sensor gap or installation
  • Oil contamination on sensors
  • Mechanical engine issues (e.g., worn components)

Common misdiagnoses

  • Faulty crankshaft position sensor
  • Faulty camshaft position sensor
  • Timing belt/chain issues
  • Ignition system problems
  • Fuel system issues
  • Engine control module (ECM) failure
  • Wiring or connector issues
  • Vacuum leaks
  • Incorrectly installed or damaged timing components
  • Other sensor malfunctions (e.g., throttle position sensor)

Troubleshooting steps

  1. 1. Check for Additional Codes

    Use an OBD-II scanner to check for any other trouble codes that may be present. This can provide more context and help identify related issues

  2. 2. Inspect the Crankshaft and Camshaft Sensors

    Visual Inspection: Check the sensors for physical damage, corrosion, or loose connections

  3. 3. Wiring and Connectors

    Inspect the wiring harness and connectors for fraying, breaks, or poor connections

  4. 4. Test the Sensors

    Resistance Test: Use a multimeter to check the resistance of the crankshaft and camshaft sensors. Compare the readings to the specifications in the vehicle’s service manual

  5. 5. Signal Test

    Use an oscilloscope or a multimeter to check the output signal of the sensors while the engine is running. The signal should be within the specified range

  6. 6. Check Timing Alignment

    Ensure that the timing belt or chain is properly aligned. A misaligned timing component can cause the crankshaft and camshaft to be out of sync, triggering the P1336 code

  7. 7. Inspect the Timing Components

    Check for wear or damage in the timing belt/chain, tensioners, and guides. Replace any worn components as necessary

  8. 8. Check Engine Ground

    Ensure that the engine ground connections are clean and secure. Poor grounding can lead to sensor performance issues

  9. 9. Examine the Engine Control Module (ECM)

    In rare cases, the ECM may be faulty. Check for software updates or reprogramming if necessary

  10. 10. Clear the Codes and Test Drive

    After performing any repairs or adjustments, clear the trouble codes and take the vehicle for a test drive to see if the P1336 code returns

  11. 11. Consult a Professional

    If the issue persists after performing the above steps, it may be necessary to consult a professional mechanic for further diagnosis.Additional Considerations

  12. 12. Fuel Quality

    Ensure that the vehicle is using the correct fuel type, as poor fuel quality can sometimes lead to performance issues

  13. 13. Vacuum Leaks

    Check for any vacuum leaks that could affect engine performance. By following these troubleshooting steps, you should be able to identify and resolve the underlying issue causing the P1336 code
