P0128 code coolant temp below regulating temp
Just replaced my thermostat housing on and thermostat on my lr3 (v8) and I’m getting a p0128 intermittent code and check engine light. I tried topping off coolant and releasing the air via the screw, but still throwing the code. Any thoughts? Not overheating and temp needle is halfway.

Did the new housing come with a new temp sensor? Is the new sensor properly connected? Are the sensor wires still in good condition? Can you read the voltage from the sensor and see what it is doing?
