Error code P1340 in Volvo and Land Rover vehicles indicates a plausibility error in the camshaft position sensor for bank 1. This means the engine control module (ECM) is detecting an inconsistent signal from the camshaft position sensor, which can cause rough running, poor fuel economy, and potential starting issues. Ignoring this code can lead to more serious engine damage.

Frequently Asked Questions

Can I drive with error code P1340?
It is not recommended. The error can cause poor performance and may lead to engine stalling or damage if the timing is off.
What causes P1340 in Volvo and Land Rover?
Common causes include a faulty camshaft position sensor, wiring issues, or incorrect engine timing due to a stretched timing chain or skipped belt.
How much does it cost to fix P1340?
If just the sensor needs replacement, parts cost $50-$150 and labor $100-$200. Timing repairs can cost $500-$1500.
Can a bad camshaft sensor cause engine misfire?
Yes, a failing camshaft position sensor can cause misfires, rough idle, and hesitation because the ECM uses it for fuel injection and ignition timing.
Is P1340 the same as P0340?
No. P0340 is a generic circuit malfunction for the camshaft position sensor. P1340 is a manufacturer-specific code indicating a plausibility error (signal out of range).
