Engine coolant temp sensor was created by jbailey91
I have a 1997 chevy k1500 4.3 W/T. I replaced the engine with one from a 1999 GMC Jimmy. I'm getting code p0118 ect circuit high input. The sensor from the 1997 was a single wire sensor( I assume it gets ground from the block). The 1999 jimmy engine has a 2 wire connector. Can i take that second wire which is black and just run it to a frame/engine ground? This engine has 2 ECT sensors, one is near thermostat which sends signal to the computer and the second one is near the exhaust manifold which controls the gauge. Fhe sensor im referring to is the second one by the manifold. Attached is a photo the red wire is whats connected to the engine harness(green wire on harness i believe).

Can you not thread the single wire sensor into the bung?
