Just had a spurios pegging of oil temp gauge. This is very similar to the pegging when the oil pressure sensor is bad. Could be a cabling issue. Any experience with this issue? Where would you start the diagnosis? I have wiring diagrams to dive in but wanted to get the collective wisdom and experience on this here first.

thanks.

I had the same intermittent issue. Not a good time the first time it happened at the track!

I cleaned the contacts at the temperature sender, and also the gauge contacts themselves. Problem persisted.

A tap on the gauge glass could be telling - mine was cleary a faulty instrument. Tapping the glass would reset the reading accuracy, if temporarily.

So, at least 3 easy places to check. I would try tapping the gauge face gently first. If that settles down the reading, just send it out to NH or PA speedo for a refurb.

Good luck.

Best,

Matt

Definitely sounds electrical. If you can borrow a gauge, that's a good place to start as its easy to swap.

Thanks for input. Let's wait for the next incident and keep testing.
