Hi

I could use some help diagnosing a problem with oil temp gauge. It does not read temp. it has power and wiring looks good. If some know how to test it for fault i would appreciate it

It's probably not hooked up at the oil pan/sandwich plate?

:shrug:

 

[lotus90]

it plugs into the BOE pan and yes it is connected. I am not that challenged

A volt meter using resistance (ohms) would be a good place to start.
Check 12V, ground and voltage from the sender (or resistence), depending if it is powered or not.

Just checking

Do you have a multimeter?

If you are absolutely sure it is getting power/signal from the sending unit, then the gauge is probably kaput.

If the sender is powered ground the wire. The gauge should go the max. If it does the sender is bad. If it doesn't the gauge is bad. If you are certain there is power.

There are auto-sparkies (Auto-Electricians) non bother sides of I70 (and I25). Just to to any of them.

I have a multimeter i will try

sender is powered ground the wire. The gauge should go the max. If it does the sender is bad. If it doesn't the gauge is bad.

thanks

It's not unheard of to have a bad sensor right out of the box. Happened to me once and had me scratching my head.

Most likely the sender (sensor). I've had one go bad --broken connection. The kind I had was a simple one-wire thermistor. Its resistance, measured with respect to the grounded pan, changed as the temp changed.
