    Exclamation Whats this sensor called?

    Hey guys I started to put on my pacesetter long tubes about 4 hours ago... So far I got the EGR valve off, and the Whole air pump system off hoses and all.. I also have every bit of my exhaust off only thing left is the exhaust manifolds... I decided to start on the driver side first (becasue it looked easier) well I was using a 10MM wrench to break them loose and well that sensor by #1 cylinder got in the way and I kinda broke it! haha.. I would call it a sensor, it has 2 prongs and the plug in plugs in Right next the the #1 cylinder exhaust manifold bolt.. Whats this thing called so I can pick one up today

    I think its the water temp sensor not 100% sure. If you have it off take it to the parts store with you. Or alot aff parts stores can look it up and tell you where it goes...

    YEP! that's it. You can run the car with out it, you'll just get a code and the temp gauge won't work

    ECT sensor, not expensive. I wouldn't run the car long without it, the PCM needs the coolant temp.

    yeah, replace that sensor before driving the car. It'll screw with your AFR.

    Different years have specific sending units. So you can't just match one that looks like yours. My 98 has a 3 wire connector where yours has 2 wire connector. And if you just find one that looks like yours if its resistance isn't the same your gonna get some weird readings. Your probally gonna have to reset the CPU when you replace it. Right now your timing advance, air/fuel ratio and fan activation is all screwed up. My 98 NEVER thru a code. However it was running rich, started spark knocking and got to the point that it wouldn't even crank up unless you gave the gas pedal a hard time! <$20 at the GM place and she fired right up! My CPU thought it was 35 degrees outside all the time!
