What does P0019 mean?

P0019 is a generic (SAE standard) powertrain code reported by your car’s engine control unit. It sits in the P00xx block, which covers fuel and air metering. The stored description is “Crankshaft Position - Camshaft Position Correlation”. The code itself tells you which circuit or system tripped the fault — not always the exact part that failed.

Will P0019 fail an MOT?

MOT testers fail an illuminated malfunction indicator as Major. P0019 is Bank 2 Sensor B correlation, distinct from P0017 and P0018, and is not a catalyst-efficiency result.
