So on my way home from town tonight I glance up at my OHC and note it says 83*F. I glance back out the window at the snow on the ground that is definitely far from melting. Glance back up at the OHC... nope... not crazy. It says 83*F.

Just great. So either my engine is running way too hot, my OHC is malfunctioning or the temp sensor is shot. Engine didn't seem abnormally warm to the hand when I got home (my thermostat on the gauge cluster doesn't work), so I suspect a problem with the OHC.

Just great. I'll have to make a point to watch the temperature tomorrow as I head into work.

 

1) where did you place the temp sensor?

2) did you hook up the VSS wire?

3) is the OHC smoking crack?

 

1) Behind the fender, driver's side headlight... over 8 months ago.

2) Yes, again... over 8 months ago.

3) Hard to say. Started off at 63F this morning, and it was NOT 63 outside. Definitely not the engine overheating.

Been working fine for a long time now up to yesterday.

 

almost sounds like something in the electronics is fried... i recently bought a new ohc to replace my old one with broken map lights and it was always showing much warmer than it really was outside. Cant guarantee thats what it is, but i swapped in my old display and its been accurate now

 

I have a spare temperature sensor, if you determine that's what caused the problem. However, keep in mind the sensor works the same as a potentiometer. As the temperature rises, so does the resistance on the circuit. Maybe something is causing extra resistance on the temp sensor circuit? Maybe it's getting a ground fault?

 

mine does that..i put in an older ohc with newer temp sensor.its always like below zero so i just shut the dern thing off

 

Actually I believe it's the inverse of that, since an open circuit reads -40F. I'm trying to dig up my spare OHC parts (I know they're around here _SOMEWHERE_). If anything it would be a short between the two.

 

mine does the same just not as much. mine was reading 44 today.. ha

 

Yeah mines about 10 degrees off, I just deal with it lol

 

Well I'm up to reading about 130F when it's probably 22F outside. So it's not so easy to just shrug off for me.
