DTC P0125:00: Notes

DTC P0125:00	Insufficient coolant temperature for closed loop fuel control
DETECTION CONDITION	The PCM monitors the ECT sensor signal after engine is started while the engine is cold. If the engine coolant temperature does not reach the expected temperature for a specified period, the PCM determines that it has taken an excessive amount of time for the engine coolant temperature to reach the temperature necessary to start closed-loop fuel control. Diagnostic support note This is a continuous monitor (engine cooling system). The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. PENDING CODE is available if the PCM detects the above malfunction condition during first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	ECT sensor connector or terminal malfunction ECT sensor malfunction PCM connector or terminal malfunction PCM malfunction
