Can a low coolant sensor cause a PCM error?
Can a low coolant sensor cause a PCM error?
The PCM and Low Coolant. Low coolant can affect the internal temperature of the engine, which is protected by the antifreeze. When the coolant is too low to effectively protect the internal temperature of the engine, the engine coolant temperature (ECT) sensor will provide a false reading to the powertrain control module (PCM).
Can a low coolant cause a check engine error?
Low coolant in the radiator of your car can trigger the malfunction illumination light (MIL), also known as the “check engine” light.

What does a misfire code on a check engine light mean?
Misfires that turn on the check engine light and log a cylinder-specific fault code are the easiest to diagnose. The OBD II system will identify the cylinder (s) that are not contributing their normal dose of power and set a code that corresponds to the firing order. A P0303 code, for example, would tell you that the No. 3 cylinder is misfiring.
What is the fault code for a mid 128 engine?
Engine ECU Faults (MID 128) Fault Code Description FMI Codes MID 128 PID 26 Engine Fan Speed Percent 3,8 MID 128 PID 27 EGR Valve #1 Position Sensor 3,4,5 MID 128 PID 45 Preheater Relay Status 3,4,5 MID 128 PID 81 Particulate Filter 0,2,3,5,12
What is the diagnostic code for insufficient coolant?
P0125 OBD-II Trouble Code: Insufficient Coolant Temperature for Closed Loop Fuel Control. Cost of diagnosing the P0125 code. P0125 is a diagnostic trouble code (DTC) for “Insufficient Coolant Temperature for Closed Loop Fuel Control”.
The PCM and Low Coolant. Low coolant can affect the internal temperature of the engine, which is protected by the antifreeze. When the coolant is too low to effectively protect the internal temperature of the engine, the engine coolant temperature (ECT) sensor will provide a false reading to the powertrain control module (PCM).
What does insufficient coolant temperature for closed loop fuel control mean?
Insufficient Coolant Temperature For Closed Loop Fuel Control What the P0125 code means P0125 is the OBD-II generic code for the engine computer, or Engine Control Module (ECM), not detecting enough heat in the cooling system before the fuel management system can take control.
