miked808 Posted May 21, 2007 Share Posted May 21, 2007 My Engine Temp. Guage that is on the left side of my Dash is not working at all. My Car also has no power when I first start it Cold so I was thinking it must be running rich because it thinks the Temp. is so low. Is this a Coolant Temp. Switch problem or should I look for something else. Quote Link to comment Share on other sites More sharing options...
steviej Posted May 24, 2007 Share Posted May 24, 2007 most likely coolant temperature sensor itself. is the CEL lit up? steviej Quote Link to comment Share on other sites More sharing options...
miked808 Posted May 24, 2007 Author Share Posted May 24, 2007 Yeah the CEl is lit up but the procedure to check the codes (meaning the paperclip in the diagnostic port) doesn't work for me. I did hook it up to a scanner recently and I got a code for o2 sensor 1 bank 1. I am about to replace all o2 and a/f sensors but I wanted to know if the Coolant Temp. Switch is the reason my temp guage doesn't rise pass Cold on my Instrument panel. Quote Link to comment Share on other sites More sharing options...
