where is the IAT sensor and should I install a chip to jumper out this sensor
I purchased a DTPC chip for my car it says to install it where the IAT sensor plugs into and I am wondering should I and where is it, and which two sensor wires should it hook up to.
Your chip is telling you to jumper out the Intake Air Temperature Sensor, ostensibly in order to send a pre-programmed air temperature to the ECM and force a fixed fuel-air mixture for "more power." I would suggest NOT doing this, as this will adversely affect your fuel economy, possibly your emissions test results, and quite frankly, may not even provide THAT much of a power gain. The IAT sensor is usually located in the bottom of the air box, to measure the temperature of the air after it passes through the air filter but before it enters the throttle body.
it should be somewere between the air filter and the TB should be a two wire plug I duno how this chip works but I wouldn't touch it it works with your MAF or Baro sensor to tell the comp how much fuel to throw in does this module plug in between the pcm and harness if so it probably is telling the computer different info so it will put more fuel in if it says to do it go ahead i'm sure its been tested and tuned to do that or and BTW this will affect your warranty if you care
