P1340 — Camshaft/Crankshaft Position Sensor Signals Out of Sequence
CAUTIONIs it safe to drive? Drive gently and get it looked at soon — it can worsen or fail inspection.
What P1340 means
This is a manufacturer-specific code — its meaning depends on the vehicle’s make (see below).
What P1340 means on specific makes
VW / Audi CAUTION
VW/Audi P1-code: the cam and crank signals are not correlating in sequence. Like P0341, on VAG this points toward timing-chain/belt or cam-sensor faults rather than a single sensor.
- Timing chain stretch / tensioner (chain engines) ($1,000-2,500)
- Cam or crank position sensor ($50-150)
- Skipped timing belt tooth (belt engines)
- Reluctor/trigger wheel
Check first: Verify cam-crank correlation and chain/belt condition. On EA888 chain engines suspect the tensioner.
