I'm Awesome
Can anyone tell me why I would have 2 ECT sensors on my 1992 k1500? I never really paid that much attention until today when I noticed it was taking forever for the truck to warm up, but it dawned on me that there is 1 on the intake with the 2 prong pigtail, and 1 single wire sensor between the 1 and 3 cylinders. The one between the cylinders directly impacted my gauge reading awhile back. I had to clip the wire and put another terminal on it and it worked perfect for a couple months. But now it's not reading above 125° no matter how long it's been running or driven. I replaced the one on the intake awhile back when I replaced the thermostat and radiator, so I know its good, but I don't know what to think about the side sensor now. I'm going to replace the thermostat again tomorrow just to be on the safe side since it's acting like it's stuck closed.
