Question. I've heard that the 'vette has an oil temperature sensor. Is that just a gauge, or does the ECM read it as well? If the ECM reads it, what does it do with that data? Alter engine parameters? Feed it in the ALDL stream? Anything else?

 

What year Vette.
They probably use it on the PCM stuff. I don't recall seeing anything on the 6E or 8D masks about it.

 

I thought that late C4 corvettes had oil temperature sensors... I *thought* that they fed the ECM.

Here's something that makes reference to code 62, oil temperature <A HREF="http://www.applink.net/cct/tips/codes.html">http://www.applink.net/cct/tips/codes.html</A>

Ecklers sells an <A HREF="http://www.ecklers.com/product.asp?dept%5Fid=1309&pf%5Fid=20117">Oil Temperature Sensor</A> for '81 to '89 'vettes.

Upon further investigation, though, it looks like it's a switch, not an analog device. The picture at Ecklers kind of confirms that. Any idea what the 'vette code might do if it detects an over temperature condition aside from setting a trouble code?
