Where is the iat sensor located on a 1999 chevy cavalier 4cyl


The Intake Air Temperature (IAT) sensor determines the air temperature inside the intake manifold. Resistance changes in response to the ambient air temperature. The sensor has a negative temperature coefficient. As the temperature of the sensor rises the resistance across the sensor decreases. This provides a signal to the PCM indicating the temperature of the incoming air charge. This sensor helps the PCM to determine spark timing and air/fuel ratio. Information from this sensor is added to the pressure sensor information to calculate the air mass being sent to the cylinders. The IAT is a two wire sensor, a 5-volt reference signal is sent to the sensor and the signal return is based upon the change in the measured resistance due to temperature.

Hope helped.

Motor mount on 95 Cavalier


Depends on which one you are replacing? If you are replacing the upper one on the belt end of the engine, yes it's on the passenger side and it is fairly easy to change. You need to jack up the engine with a floor jack and a woodblock to change it.

95 cavalier Computer


I have a 95 cavalier and am currently replacing the pcm. It isn't located under the dash. It is in front of the right wheel. You have to jack it up remove the right front wheel, and splash guard. I also suggest removing the bumper for easier access. You may have the remove the horn assembly to remove the pcm. I ended up bending my because well I'm lazy and my horn was going to be a pain in the **** to remove plus it didn't work. You should see 2 or 3 wire connectors coming out of it. Make sure you label them before removing them. They should be label anyhow but just incase.
