COOLANT IN PCM With growing fuel costs and problems of global warming that are being faced by our planet, automotive industry is trying its best to create cars and engines that are more fuel efficient

...PCM/ECM indicating the engine coolant temperature. The engine coolant temperature gage defaults to 100°F (38°C) if there is a malfunction in the engine coolant temperature sensor or the IPC detects a ...

PCM determines engine coolant temperature from the coolant temperature sensor.As coolant temperature varies the coolant temperature sensors resistance changes resulting in a different input voltage to

...PCM monitors voltage drop to determine coolant temperature. If the ECT reads less than freezing temp. when engine has been running for more than a few minutes, the PCM determines a circuit fault and ...

...coolant temp. reaches The PCM commands the low-speed fans ON under the following conditions: • The engine coolant temperature exceeds approximately 106°C (223°F). • The transmission fluid temperature ...

...PCM indicating the engine coolant temperature. The engine coolant temperature gage defaults to 60°C (140°F) or below if: • The PCM detects a malfunction in the engine coolant temperature sensor ...

PCM) sends out a coolant loss signal over the coolant level switch signal circuit. When the engine coolant level switch reads a low coolant level in the fill tank, the switch opens. The message center

...PCM indicating the engine coolant temperature. The BCM converts the engine coolant temperature into a percent gage deflection. The IPC receives a message from the BCM via the serial peripheral ...

...rule out these other possibilities. If you're unsure of how to diagnose a PCM, do not attempt. Other engine coolant engine light codes: P0115, P0116, P0117, P0118, P0119, P0125, P0128 Hope
