CMP/CKP Position Sensor Circuit - CKP Dynamic Plausibility

Test 1:

Test 2 - 5:

Test 6 - 8:

SYMPTOM
P1354-CMP/CKP POSITION SENSOR CIRCUIT - CKP DYNAMIC PLAUSIBILITY

WHEN MONITORED
The engine speed is above 790 RPM.

SET CONDITION
The ECM compares the current crankshaft RPM to the last calculated crankshaft RPM and the acceleration or deceleration is greater than is physically possible.

POSSIBLE CAUSES
- Crankshaft position sensor
- Engine control module
- Open shield circuit
- Intermittent condition
- Crankshaft position sensor signal circuit(s) shorted to ground
- CKP sensor circuits shorted together
- CKP sensor signal circuits open
- CKP sensor signal circuit(s) shorted to voltage
