Thank you for your response, First, advance auto hooked their device to the car's computer to read out the "engine needs service soon lite" thats where I got the TPS, and the IAT numbers I referenced. I already checked the IAT and it was left unplugged at the last servicing, thats when the lite came on and would not go off. I plugged it back in and the lite has not gone off yet. I have not driven the car tho since i plugged it back in, only started it up and lite still was shown. what does BTW stand for? what about the TPS sensor, should I replace it?(if i can find it) Thanks Joel
