P0219 - ENGINE OVERSPEED CONDITION

POST UPDATED IN February, 2023

Description of DTC code P0219 Generic

The P0219 OBDII fault code basically indicates that the PCM (Powertrain Control Module) has found RPM (Revolutions Per Minute) level is above the maximum level.

To determine if an overspeed condition exists, the vehicle’s computer uses the input signals from the CKP (Crankshaft Position Sensor) and CMP (Camshaft Position Sensor). In most cases, this condition is automatically checked by a rev limiting device once the transmission is in neutral.

When such a condition is found, fuel injection and ignition timing may be limited to decrease the engine RPM until the engine RPM returns to an acceptable level. If the PCM fails to return the RPM to acceptable levels, the P0219 code will be set.

Symptoms of fault code P0219 Generic

  • Check Engine light ON.
  • Acceleration problems.
  • In a manual transmission, the clutch slips.
  • Stored DTCs related to the Knock Sensor (KS).

Causes of OBD2 P0219 Generic

  • The CKP Sensor, CMP Sensor, and Transmission Speed Sensor system may have problems in their circuitry.
  • The CMP Sensor or CKP Sensor may be faulty.
  • Possibly the transmission speed sensor is in bad condition.

Possible solutions of the DTC code P0219 Generic

To resolve the P0219 OBDII error code, try this:

  • Refer to the Technical Service Bulletins. The information they provide is helpful in diagnosis. Also, before performing the diagnosis, make sure the vehicle has not been operated at RPM levels higher than those recommended by the manufacturer. Also, check that the clutch is working properly.
  • Follow the manufacturer's recommendations for testing the Crankshaft Position Sensor, the Camshaft Position Sensor, and the Transmission Speed Sensor. Replace any sensors that do not meet requirements.
  • Perform voltage tests on the circuits related to the system. Check the reference voltage and grounding of each. Also, check for continuity and resistance. Fix if necessary.
