    Spark plug change goes wrong!

    So I was changing the spark plug for cylinder 1 and I unplugged the plug that is right next to it to make it easier. Somehow it just completely ripped off! Can I just like super glue it back on or something? Help please! I attach a pic to make it easier to know what I'm saying lol.

    Thanks for the input

    Looking thru the list of sensors thread it looks like the Engine Coolant Temperature (ECT) sensor. Any ideas how to repair it?

    Just replace it. The PCM needs to know engine temp to control open and closed loop fueling, among other things. I wouldn't risk it and recommend you pick up a new one from the dealership in lieu of a parts store cheapie. If you are quick about it, you should be able to swap out the sensor with minimal coolant loss. You'll create an air pocket, so watch your temp the next time you start the engine to ensure that you do not airlock the thermostat. Other than that, it's a simple fix.

    X2 what pajeff02 said. It's a cheap fix and not worth trying to 1/2 a$$ it. I did the same thing when I did my 1st plug change. I broke the end off of the sensor. I tried to "ridge" it, but it keep falling off. I just bought a new sensor and some antifreeze. Replaced the sensor and didn't even loose enough antifreeze to make a difference in the water level.

    How do I replace it? Just unscrew the brass part and put a new one in?

    Get the $35 replacement and either use thread sealant or teflon tape around the threads. Use a 3/4" socket or wrench and back it off. Have a drip pan because it's going to drain the coolant. Replace and tighten down.


    I had the same situation like you, my sensor worked for a while but in time it started giving bad readings. Once I swapped it out everything fine again.
