[QUOTE="theboss, post: 117533, member: 1458"] Hi Darryl. This sensor work as your choke use to work on your old carburated engine so ambient temperature should not be a probleme as long as the ohm reading of the sensor fallow the coolant temperature. warm it up until the problem is present, turn the engine off then take the reading on the 2 pins of the sensor. Also check for traces of coolant in the connector, these sensor use to leak. I remember back then I was using a variable resistor to simulate the coolant sensor, this way I could see if the PCM was working OK with a good reading. Stephane [/QUOTE]
