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 diagram below is straight from the BGB.

but from what year, i just looked up the 95 celica 7AFE engine control BGB wiring diagram at celicatech and there is no short pin shown. the ecm may be different, shorting a circuit grounded or controled by the ecm could cause damage to it...

That is because all ST's are CA spec like Dustin mentioned above.
See the second post, the resistance of the temp sensor is exponentially approaching zero when the temp. goes up.
And normal exhaust temp is much higher than that.
But if you don't feel comfortable with this, don't do it.
