Hello All,
I hope someone can help me out a little bit. Does any one know the electrical characteristics of the cylinder head temperature sensor ? As in what is the resistance range over a given temperature range ? I know the resistance goes down as the temperature goes up. Also, as the temperature increases, does this sensor enrich or derich the fuel mixture ? I am looking to bias my sensor a little to try and correct a wicked rich condition. Thanks for any info you may have.

I don't remember the resistance values off the top of my head...

The resistance drops as it heats up (thermistor). It's designed for enrichment when themotor is cold. So as the engine heats up, and the resistance drops, the ECU leans out the mixture. A common "patch" is to place a 270 ohm resistor in-line with the HTS to richen the mixture up a little.
