IAT Sensor: High Current

Hey, as you can guess... I have put a CAI on the car ('97 Eclipse RS)... the other day, leaving work... my CEL light came on... I panicked and got the code checked... it said IAT: High Current...

I'm almost certain that's the intake's fault... What can I do to correct this issue... b/c I can't get it inspected with the CEL on...

The CAI really has nothing to do with that. People put them on everyday and run them for the life of the car with no problems.

Try putting on the stock airbox and reset the code and see if it comes up. The sensor could be bad, but only shows when the CAI is installed

Is there a MAS on the 420 (DOHC, NT) Eclipses?

I don't see one... I had one on my Stealth... but don't see one on my Eclipse... the CEL is on, says high current (IAT sensor)... I have installed a short-ram and disconnected the valve cover hose for now (til I buy a crank case breather filter)... would that cause the sensor to show bad?

anything else... I'm going to the beach tomorrow, but I want this fixed... the car idles really high now... when I left off gas, it stays at 2k for a few seconds, then drops down slowly

Try adjusting the throttle cable and make sure it's on right. Disconnect the battery for a couple minutes to erase the codes and then reconnect it. Drive the car and see if the CEL comes back.

ok, will do

ok... I finally found the time to play around with the car... turns out, sure enough the IAT is fried... the wire harness (from the car) is broken (the clip)... but it still fits onto the sensor... I took the sensor out of the car... and there's some internal pieces hanging... so I'm certain that the sensor is busted... I have put a resistor into the harness (like an e-bay speed chip)... right now I have a 3100 ohm resistor... what would be the best hp gain/safe resistor rating... I'm still gonna get a new IAT, just want a couple extra hp out of the car...

hah, that chip works wonders... my car now blows black smoke (under hard acceleration, and before shifts) but it's faster

Wait, so you put a resistor in place of the IAT? That can't be good, can it? Your're going to see problems with that I believe.

Actually, that's the "ebay-speed chip"... the resistor sends a certain signal (based on resistance) to the ECU... the different readings trick the ECU to make it think the air outside is colder than it actually is... therefore giving the car more gas and advancing the timing 3°... that means extra hp and faster 1/4 times.... it is also a lot faster off the line... It actually takes the IAT out of the loop(since mine broke anyway)...

you will notice black smoke under hard acceleration(runs a little richer), and a slight decrease in MPG... but I have noted less than a 3 MPG loss...
