P0336 — Crankshaft Position Sensor A Circuit Range/Performance

serious

What it means

A signal from crankshaft position sensor A is present, but its pattern does not match what the module expects: pulses are missing or extra, the amplitude is too low, or the synchronisation gap does not line up with the camshaft signal. This is a classic sign of a damaged reluctor wheel or a marginal sensor rather than an open circuit. Symptoms are long cranking, random stalling, jerking under load and unstable idle that comes and goes with engine temperature.

Likely causes (most common first)

  1. Damaged, cracked or contaminated reluctor wheel teeth
  2. Excessive or uneven air gap, loose sensor mounting bolt
  3. Ageing sensor that loses signal amplitude when hot
  4. Damaged screening or an intermittent contact in the connector
  5. Stretched timing chain or belt, sheared crankshaft key: lost correlation with the camshaft signal
  6. Faulty ECM signal processing circuit

Can you drive with it?

A short trip to the workshop is possible, but expect sudden stalling under load or when hot.
