P0016: Crankshaft / camshaft timing correlation

The ECU sees the crankshaft and camshaft signals outside their expected relationship.

Fault-Code Library

Common symptoms

  • •Long cranking
  • •Rough running
  • •Reduced power
  • •Cold-start rattle

Likely causes

  • •Stretched or incorrectly installed timing drive
  • •Cam or crank sensor signal fault
  • •Oil-pressure or variable-timing control issue

First checks

  • •Confirm oil level and correct oil specification
  • •Read freeze-frame and manufacturer-specific timing values
  • •Inspect timing mechanically before replacing sensors

Important

Continued driving can risk internal engine damage when mechanical timing is genuinely incorrect.

A fault code identifies a detected condition, not a failed part. Confirm manufacturer-specific subcodes and live data.
