Circuit/System Verification
- Attempt to start the engine, observe the DTC information with a scan tool. DTC P0335 and P0336 should not set.
- Observe the Engine Speed parameter while cranking the engine. The scan tool should indicate an engine speed greater than 0 RPM.
- Move related harnesses/connectors of the CKP sensor and verify the engine does not stumble, stall, or change engine speed.
- If the vehicle passes the Circuit/System Verification test, then operate the vehicle within the conditions for running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records List.
IMPORTANT:
If you were sent here from Engine Cranks but Does Not Run, proceed to Circuit/System Testing.
