DTC 214: Rpm Sensor Signal Sporadic

  1. Check RPM sensor and ECM connectors for loose connection, contact resistance and oxidation. Repair as necessary. Check wiring for short circuit to ground or voltage.
  2. If all wiring and connections are okay, check connecting flange/flywheel through sensor hole for damage and scratches. If no damage is present, retest using new RPM sensor.
