Which is a bad coolant temp sensor code?
Coolant temp sensor is bad. PCM is bad. This code indicates that the PCM is seeing a high voltage drop across the ECT sensor, which it’s translating as an extremely hot coolant condition. When the PCM senses this high voltage input, it will translate this voltage input to a coolant temperature of -46° F (-50° C).
How does the coolant temp sensor work on a PCM?
When the PCM senses this high voltage input, it will translate this voltage input to a coolant temperature of -46° F (-50° C). Coolant temp sensor’s wires have an ‘open-circuit’ problem (usually due to a cut wire).

What should the temperature be on the ECT sensor?
Usually around 250° F, even tho’ the engine is cold. This condition leads the PCM to register a P0118 DTC. It will receive input from the ECT sensor showing an extremely low temperature.

How to troubleshoot the engine coolant temperature ( ECT ) sensor?
This article will help you to troubleshoot the engine coolant temperature (ECT) sensor on your GM 4.3L, 5.0L, or 5.7L equipped pick up, van, mini-van or SUV. You can either use a multimeter or a scan tool (w/ Live Data capability) to diagnose the ECT sensor and/or trouble codes.
When the PCM senses this high voltage input, it will translate this voltage input to a coolant temperature of -46° F (-50° C). Coolant temp sensor’s wires have an ‘open-circuit’ problem (usually due to a cut wire).
