PCM DTC Chart
WARNING: This page is about a different variant/trim than selected.
| DTC | Description | Action |
|---|---|---|
| P0125 | Insufficient Coolant Temp For Closed Loop Fuel Control | Go to PINPOINT TEST C |
| P0128 | Coolant Thermostat (Coolant Temp Below Thermostat Regulating Temperature) | Go to PINPOINT TEST C |
| P0217 | Engine Coolant Overtemperature Condition | Go to PINPOINT TEST B |
| P0480 | Fan 1 Control Circuit | Refer to ENGINE CONTROLS - INTRODUCTION (EXCEPT DIESEL & HYBRID) (SECTION 0) . |
| P1299 | Cylinder Head Overtemperature Protection Active | Sets in the PCMPCM when a cooling system fault was detected. A failure mode effects management strategy called fail-safe cooling was activated to protect the engine. Diagnose all other DTC's first. If no other DTC's are present. Go to PINPOINT TEST B |
| P1940 | Engine Coolant Level Signal Not Available Due To Driving Conditions | Engine Coolant Level Signal Not Available Due To Driving Conditions |
| P2556 | Engine Coolant Level Sensor/Switch Circuit | Sets when there is an internal sensor fault. The sensor is still communicating on the CAN bus, but is unable to detect coolant level due to the internal circuit fault. INSTALL a new coolant stand-pipe. |
| P2557 | Sets when there is an internal sensor fault. The sensor is still communicating on the CAN bus, but is unable to detect coolant level due to the internal circuit fault. INSTALL a new coolant stand-pipe. | Sets when the coolant level signal is irrational or noisy (rapid change) for a calibrated time. Inspect the upper and lower stand pipe hoses for being kinked. If the hoses are not kinked clear the PCM DTCs and repeat the PCM self test. If the DTC is still present INSTALL a new coolant stand-pipe. |
| P2560 | Engine Coolant Level Low | Sets when the coolant level is below a calibrated threshold between empty and the MIN and MAX lines. Diagnose the cause of loss of coolant. Go to PINPOINT TEST A . |
| P2681 | Engine Coolant Bypass Valve "A" Control Circuit/Open | Refer to: TRANSMISSION COOLING . |
| P26AC | Engine Coolant Bypass Valve "B" Control Circuit/Open | Refer to: TRANSMISSION COOLING . |
| P26B7 | Engine Coolant Bypass Valve "C" Control Circuit/Open | Go to PINPOINT TEST D |
| P26BD | Engine Coolant Bypass Valve "D" Control Circuit/Open | Go to PINPOINT TEST E |
