P1340 on Land Rover: How to Diagnose & Fix

P1340 stands for "Crankshaft/Camshaft Position Sensor Signals Out of Sequence (VW/Audi)." This is a manufacturer-specific powertrain code and the definition depends on the brand. On Volkswagen and Audi it means the engine control module saw the crankshaft and camshaft position signals out of sequence — the two are no longer correlated the way valve timing requires. Ford applies P1340 to a Camshaft Position Sensor 'B' circuit malfunction, and Toyota to Camshaft Position Sensor 'A', Bank 1, Sensor 2, so confirm the definition for your make before buying parts. On VW/Audi it very often follows timing belt or chain work, where being even one tooth off will set the code, and it is common on VR6/V6 engines with stretched timing chains. On Land Rover it is documented across 1 model: Defender.

The most common causes of P1340 are: Timing belt or timing chain off by one or more teeth (often after a belt/chain job), Stretched timing chain or worn chain tensioner/guides, Failing camshaft position sensor, Failing crankshaft position sensor or damaged reluctor/tone ring, Wiring, connector, or shield/ground problems in the cam or crank sensor circuits, Faulty variable valve timing actuator affecting cam phasing. The specific cause varies by vehicle.

Published repair estimates on Land Rover range from $30 to $250 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
