I cannot find any diagrams or explanations for this code, only the code description. When I disconnect the sensor the car shuts off. I assume this means I am actually getting a signal however not constant. What do I do?

Hi AutoEd09,

Here are the descriptions and diagnostic procedures.

DTC P1381: CYP SENSOR INTERMITTENT INTERRUPTION, DTC P1382 : CYP SENSOR NO SIGNAL

1 . Reset the ECM/PCM

2 . Start the engine.
Is DTC P1381, and/or P1382 indicated?
YES - Go to step 3.
NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at the distributor and the ECM/PCM.

Are the wires OK?
YES - Go to step 4.
NO - Correct as necessary.

NO - Repair open in the wire between the ECM/PCM (C29, C30) and the distributor.

12 . Check for continuity between body ground and ECM/PCM connector terminal C29.

Is there continuity?
YES - Repair short in the wire between the ECM/PCM (C29) and the distributor.
NO - Substitute a known-good ECM/PCM and recheck If the symptom/indication goes away, replace the original ECM/PCM.
