temp gauge revisited
Posted 31 October 2005 - 02:21 AM
What am I missing here? What's left to replace? It seems that the system is working, even to the point where my mechanic told me to forget trying to determine what's wrong. It is just that the gauge functions around the C instead of in the middle.
One thing that I must add is that replacing the gauge was a lot easier than I had been (negatively) anticipating over the past 2+ years...

Do you have good or poor heat?

Just an idea.

You should be able to measure the resistance of the sensor when the engine is at operating temperature. Remove the lead to the sensor before you take the reading. Tell us what you get for a reading and we should be able to tell you if that is correct.
If the sensor is ok and you already replaced the gauge then the problem would seem it would have to be with the power too the gauge. I would check the voltage to the input power side of the gauge, it may be low.

A resistance reading will be of more help than a voltage reading while the engine is a normal temperature. Usually the manuals show a resistance specification for the sensor.

To tell you the truth, I don't remember which one I replaced. I actually bought the sensor in the U.S. (I think itiwas about $7) and had the mechanic here in Sweden change it when the car was in for a factory recall. That was about three-plus years ago. I want to say that it was the sensor that sits right under the alternator (if that helps at all). In any case I can check the voltage.
You might have put your finger right on the problem. The sender that's right under the alternator is the oil pressure sender.
I just hope i'm getting a good understanding of what you're writing.
