Circuit/System Verification
without TCM
- Ignition ON, perform the Auxiliary Gauge Sweep test with the scan tool, verify that the transmission fluid temperature gauge sweeps from its low to high position.
- If the transmission fluid temperature gauge does not sweep, replace the P26 Auxiliary Gauge Module.
- If the engine oil pressure gauge does sweep, replace the K20 Engine Control Module.
