I'm having ABS & Traction Control trouble.

I've hooked up a OBD ll Reader.

I'm getting:

IAT Sensor 1-curcuit High Input and

EGR Pintle Position.

any help?

Doesn't quite add up, Intake Air Temp sensor and EGR should not affect ABS/TC. Try pulling your own codes without the scanner:

First off, you do not need a code reader. See the sticky in the Tech Tips section for pulling the DTC via the onboard diagnostics.

Neither of those two things have anything to do with ABS/TC. Clean the EGR valve. Again see the Tech Tips section for a tutorial. IAC sensor may need to be replaced.
