Diagnostic procedure
DTC P0342 CMP sensor circuit low input
DETECTION
CONDITION
• PCM monitors input signal from CMP sensor while engine is running. If input signal from CMP sensor is not
input at 12 crankshaft revolutions, PCM determines CMP sensor circuit low input.
POSSIBLE
CAUSE
• CMP sensor malfunction
• Connector or terminal malfunction
• Short to GND in wiring between CMP sensor terminal A and PCM terminal 81
• Short to GND in wiring between CMP sensor terminal B and PCM terminal 55
• Open circuit in wiring between CMP sensor terminal A and PCM terminal 81
• Open circuit in wiring between CMP sensor terminal B and PCM terminal 55
• PCM malfunction
STEP INSPECTION ACTION
1 VERIFY RELATED REPAIR INFORMATION
AVAILABILITY
• Check for related Service Information
availability.
• Is any related repair information available?
Yes Perform repair or diagnosis according to available Service
Information.
• If vehicle is not repaired, go to next step.

• Inspect for poor connection (damaged, pulled-
out terminals, corrosion, etc.).
• Is there any malfunction?
Yes Repair or replace suspected terminal, go to Step 7.
No Go to next step.
3 INSPECT CMP SENSOR CIRCUIT FOR SHORT
TO GND
• Turn engine switch to OFF.
• Inspect continuity between following
harnesses:
— CMP sensor terminal A and body GND.
— CMP sensor terminal B and body GND.
• Is there continuity?
Yes Repair or replace harness for short to GND, go to Step 7.
