PCM DTC CHART
| 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) . |
| P0481 | Fan 2 Control Circuit | Refer to ENGINE CONTROLS - INTRODUCTION (EXCEPT DIESEL & HYBRID) (SECTION 0) . |
| P0691 | Fan 1 Control Circuit Low | Refer to ENGINE CONTROLS - INTRODUCTION (EXCEPT DIESEL & HYBRID) (SECTION 0) . |
| P0692 | Fan 1 Control Circuit High | Refer to ENGINE CONTROLS - INTRODUCTION (EXCEPT DIESEL & HYBRID) (SECTION 0) . |
| P0693 | Fan 2 Control Circuit Low | Refer to ENGINE CONTROLS - INTRODUCTION (EXCEPT DIESEL & HYBRID) (SECTION 0) . |
| P0694 | Fan 2 Control Circuit High | Refer to ENGINE CONTROLS - INTRODUCTION (EXCEPT DIESEL & HYBRID) (SECTION 0) . |
| P1299 | Cylinder Head Overtemperature Protection Active | GO to PINPOINT TEST B |
| P1940 | Engine Coolant Level Signal Not Available Due To Driving Conditions | Sets when the vehicle is on a very steep grade or is accelerating at a high rate for long period of time and the engine has been operating long enough in a condition that may cause overheating if the coolant level is low. Verify the coolant level is at the MAX line in the degas bottle. If the coolant is NOT below the MAX line diagnose all other DTCs first. If P1940 is the only DTC it should be cleared. |
| 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. REFER to: Coolant Stand-Pipe . |
| P2557 | Engine Coolant Level Sensor/Switch Circuit Range/Performance | 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. REFER to: 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 If a cause of loss of coolant is not identified add the correct concentration of engine coolant until the level reaches the MAX line while the engine is cold. Clear the PCM DTCs and repeat the PCM self test. If the DTC is still present INSTALL a new coolant stand-pipe. REFER to: Coolant Stand-Pipe . |
| 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 |
