Oil temp sensor

Recommended Posts

Right, I've got an SPA dual gauge that reads fuel pressure and oil temp. I had the oil temp sensor part of it measuring underbonnet temps for a while but finally fitted it to a sandwich plate a couple of weeks ago. It was very useful in giving me indication of climbing oil temps during a track day but kharked it halfway through the day - the gauge went back to reading -61degC which is what it reads when the sensor isn't plugged in.

 

The cabling was fine all the way up to the base of the sensor, I stripped and multimetered that to make sure. So I imagine something has broken inside the sensor. After it went wrong at the track day I got a reading on the gauge by bending the wiring right at the neck of the sensor, telling me a broken wire around that point. Bending the wire didn't last for long though, it's completely dead now :)

 

So, with that bit of War and Peace out the way, can I simply swap the sensor for a generic one and wire it up to the perfectly OK wiring look I have, or will I have to get in touch with an SPA dealer for a whole new oil temp sensor and wiring and plug? I imagine option a) is going to be a multiple of times cheaper than option b) :D

 

Piccy of the sensor attached, see if you can spot how far I could go testing the wiring :) If all oil temp sensors are the same, who can get me one...?

If you email SPA, you can buy a new sensor from them. I had to do this when I accidently knackered mine. I won't say how, it was embarrassing! Anyway, they sent me a new one, I can't remember how much it was, but it wasn't a lot. The guy I dealt with was called Tony Taylor, his email is [email protected], his phone no. is +44 (0) 1827 300150.
