Ignition contoller is new, so I will have Hans take a look at the temp sensor.

These can be a pain -- I've seen some on other cars (volvo) and are physically identical, but internally different, so they won't work when installed -- my sister's 92 Volvo 740 Turbo was like this -- severely overheated when the head gasket blew/radiator failed (don't know the sequence, it was fried when I got there). Temp sensors and thermostat bad, so I snagged one from a junkyard as I didn't have time to get one from the dealer. No go, the proper one had two resistors connected to the body, all the others Volvo used had a single resistor connected across the two wires. Needless to say, the check engine light stayed on a lot until we got the correct one in.

Thanks again!

Peter
