mike_flan#23 Posted January 18, 2015 Share Posted January 18, 2015 Temperature gauge isn't working any ideas where to start coolant sensor? Thermostat? Fan switch? Etc thanks Mike (ep91 na) Quote Link to post Share on other sites
FMuscle Posted January 18, 2015 Share Posted January 18, 2015 I'd say check the contacts at the sensor. Mine was always showing different readings before my swap, I reused the old sensor, same harness, and now it's always spot on. just moving it around, disconecting and reconecting fixed it.

Stu Posted January 20, 2015 Share Posted January 20, 2015 (edited) For an EP82 the temp gauge runs of a single wire sensor on the thermostat housing - pretty sure the wire colour is yellow or yellow green (sorry my notes are not handy). I can't remember off hand but pretty sure EP91 is the same single pin plug. To check if the wire to the guage is working, with the ign on (engine doesnt need to run), unplug the wire and earth it to the block or use a piece of wire into the end back to earth somewhere. The gauge should head straight up to hot. If it does that then its either the plug not connecting properly or the sensor. Good luck Edited January 20, 2015 by Stu Quote Link to post Share on other sites
