On a '90 2.3, is the only coolant sensor on the engine the one located on the underside of the intake manifold? I guess what I am asking is, is this the sensor that the ECM uses to determine engine temperature?
knowing where it is is one thing, but getting to it to replace it is a completly different story. Maybe its just me, but I'm having a helluva time getting a wrench down there.
on my car (92) there is a coolant temp sensor located in the Heater hose as it heads toward the firewall. Real easy to spot, just look for a "T" with a sensor sticking out of it near the firewall on a heater hose. If its there, you will see it.
