P1335 — Crankshaft/Camshaft Position Sensor Correlation Fault

Severity: medium Drive with care, to a shop

What P1335 means

The engine control module compares the crankshaft position sensor signal with the camshaft position sensor signal and expects a fixed relationship between them. When the pulses don't line up, it stores a correlation fault. The cause can be electrical (sensor, wiring) or mechanical (stretched timing chain or shifted cam timing). The exact definition of P1335 varies by manufacturer.

Symptoms

  • Rough idle
  • Rattle on cold start
  • Hard starting or no-start
  • Check Engine light on
  • Loss of power or hesitation

Possible causes

  1. Stretched timing chain or jumped timing
  2. Failed camshaft or crankshaft position sensor
  3. Stuck VVT actuator or solenoid
  4. Low or degraded oil affecting VVT operation
  5. Damaged wiring or connector at a sensor
  6. Timing marks set incorrectly after a repair

How to diagnose

  1. Scan all codes and freeze frame data and note any related sensor or VVT codes.
  2. Check oil level and condition; change oil and filter if needed.
  3. Inspect the crank and cam sensor connectors and wiring for corrosion, breaks or shorts to ground.
  4. Test sensor power, ground and signal pattern with a scope.
  5. Compare actual and commanded cam angle on a scan tool and check VVT solenoid operation.
  6. Assess timing chain wear: cold-start rattle, cam timing correction values, and if needed remove the cover to check marks.
  7. Verify the sensors are the correct parts and check the reluctor wheels for damage.

Common fixes

  • Replace the crankshaft or camshaft position sensor
  • Repair the wiring or connector
  • Replace or clean the VVT solenoid or phaser
  • Replace the timing chain, sprockets and tensioners
  • Change the oil to the correct grade and set timing to the marks

P1335 on different brands

Chrysler
Described as a crankshaft position (CKP) sensor circuit fault.
Dodge · manuals
Means improper operation of the crankshaft position (CKP) sensor.
Ford · manuals
The notes list this as an EGR position sensor minimum stop performance fault, which differs from the generic meaning, so check the documentation for your engine.
Hyundai · manuals
Listed in the notes as a #5 MF signal line short; confirm with the service information.
Jaguar
Means a crankshaft position (CKP) sensor circuit malfunction.
Opel · manuals
Points to a missing CKP signal at the fuel injection pump control module.
VAG
The notes list this as engine torque control limit reached on VAG vehicles.

Questions and answers

Can I drive with a P1335 code?

Only briefly, to a repair shop. If the timing chain is the cause, you risk serious engine damage, so don't put it off.

What most often causes P1335?

Usually a failing crank or cam sensor, wiring problems, a stretched timing chain, or a faulty VVT system.

Will clearing the code fix it?

Only temporarily. If the cause remains, the code will return and the engine will keep running poorly.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
