P0371

DTC P0371, sometimes indicated as P037100 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the ignition system causing timing reference high resolution signal a too many pulses.

The P0371 code means that the PCM (powertrain control module) has detected too many pulses in the high resolution timing reference signal A. This code is usually caused by a problem with the camshaft or crankshaft position sensors.
To fix this code, replace the camshaft or crankshaft position sensor as needed.

• P0371: Timing Reference High Resolution Signal A Too Many Pulses
• P0371: Timing Reference High Resolution Signal "A" Too Many Pulses
• P0371: Timing reference, high resolution signal A – too many pulses
• P0371 00: Incorrect engine speed signal from sensor "A" - too high: impulse
• P0371 00: Timing reference, high resolution signal A - too many pulses
