Chevrolet P0342

What P0342 means on a Chevrolet

On Chevrolet vehicles, P0342 is logged when the ECU detects a fault in the camshaft / VVT: “Camshaft Position Sensor A Bank 1 Low Input”. P0342 is a generic SAE code — see the universal P0342 page too.

Common causes & symptoms

Typical triggers for a camshaft / VVT code like P0342 include faulty or ageing sensors, wiring/connector faults, a clogged or removed component, or a value drifting outside the ECU's expected window. Symptoms range from a check-engine light only, to limp mode, rough running, higher consumption or failed emissions tests.

P0342 and ECU tuning

When a Chevrolet has had hardware changed for off-road/motorsport use (for example a removed DPF or EGR), the related monitor must be disabled in the ECU map or the code re-appears. Softechpro Solutions performs DPF/EGR/AdBlue/DTC off and recalculates the checksum, so codes like P0342 stay cleared after the flash. Genuine faults should always be repaired, not just hidden.
