Chad Peterson Posted May 1, 2021 Share Posted May 1, 2021 Hello everyone good afternoon, I have an electrical concern. My coolant gauge needle is stuck on cold. I’ve replaced the thermostat and the ect sensor that controls the gauge before. Ive checked the coolant temperature with a thermostat gun and the reading falls within range with what my scan tool ect reading say. That’s telling me 1 my ect sensor is giving a reading and 2 the ecu is giving me output data which is telling me there’s nothing wrong with the ecu correct? I’ve then tried jumping my ect sensor connector to see if the needle jumped to hot but nothing happened. Does anyone have a wiring diagram and connector end view so I can check for continuity/resistance from my instrument panel cluster to the ect sensor that my gauge reads? Please and thank you.
