Like Klaus said.





Code 2-1-4 (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.


Clean the sensor with a toothbrush and contact cleaner.
