Need help with resistance !, CEL GONE !!! Options

[Culpable04]

I'm gonna be replacing the EGR gas temp. sensor with a resistor, so I can clear a CEL I have, but in order to replace it with the right resistor I need to know the resistance on such sensor at normal engine operating temperatures.

the resistance changes with the temperature, if anybody know what should be the resistance at normal operating temperature or is willing to test the sensor for me, it's be a great help.


BTW. I can't test mine because the engine I have on my celi doesn't have the port for the probe to get teh temperature reading. that's how I got the CEL.

At 122F it should be 64-97 ohms, at 212F it should be 11-16 ohms, at 302F it should be 2-4 ohms. That sensor tells the ECM how hot the exhaust gas is after it goes through the EGR cooler. Depending on how hot it is (just like cooler air) is how much fuel gets injected.
