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.

the temp probe is there to tell the ecm if/when the egr is operating properly. when the egr activates the probe temperature will go up, when the egr is not activated the probe temperature will go down. you really cant fool it with a resistor. im not sure if an obd1 ecm will check if the probe temp is wrong at a certain time, but an obd2 ecm definately will. if you have the probe connected properly, ie no short or open, but it is just hanging out in the engine bay, id be willing to bet it is monitored and will set the MIL if it doesnt see the correct resistance/temp at the right time.

yeah, that makes sense

I have everything needed but my engine is from a corolla so it doesn't have the port for the probe to check the temp. so I'll have to live with the light on and the low MPG until I can source another 7AFE from a 94-95 for cheap
