PCM DTC CHART

DTC	Description	Action
P0125	Insufficient Coolant Temperature For Closed Loop Fuel Control	GO to PINPOINT TEST C .
P0128	Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature)	GO to PINPOINT TEST C .
P0217	Engine Coolant Over Temperature Condition	GO to PINPOINT TEST B .
P0480, P0481, P0482	Fan Control (FC) Circuit 1, 2 or 3, respectively	REFER to the INTRODUCTION - GAS .
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	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.
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.
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.
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 .
All Other DTCs	-	REFER to ELECTRONIC ENGINE CONTROLS .
