Where is the idle air control valve on a 2002 Saturn?

The idle air control (IAC) valve on a 2002 Saturn is typically located on the throttle body, which is found on the intake manifold. To access it, you may need to remove the air intake duct. The valve is usually mounted with screws and has an electrical connector attached. Always consult your vehicle's service manual for specific details and diagrams.


Your 1994 mercury topaz 2.3L 4-cylinder eng. has high idle all the time how can you adjust.Does it have an idler air control motor or an idle control valve going bad would appreciate some help Jerry H?

I had the exact same problem, with the same model car. You need to replace the idol air controller valve. I bought one at the local repair shop for 80$. It should not take more than a few minutes to fix. It is located on the backside of the intake manifold. It is a black box near the center,and in the back. It has an electical connection that clips on the side of the box. There will be two bolts that will require an 8mm wrench or socket to take off. This is important....the replacement part(if new from the part store) will have to be put on the Opposite of the one you take off. In other words, on the topaz model, you will be putting the new part on upside down.


1996mazda626lx rough idelling prolems high and low some times cut out?

The rough idling, high and low idle, and stalling issues with your 1996 Mazda 626 LX could be caused by several factors such as a dirty or faulty idle air control valve, a vacuum leak, a malfunctioning throttle position sensor, or a clogged fuel filter. It is recommended to have a professional mechanic diagnose the problem to properly identify and address the issue.


Why RPM fluctuates when air con is on?

There are a few things that can make the idle fluctuate. Normally the idle will drop, then rise slightly, and then return to steady when the compressor cycles on and off, or when the cooling fans turn on and off as well. The added draw on the engine causes it to compensate for the load. A problematic cause would be a faulty idle compensator. This piece activates when the AC is turned on and raises the engine rpm to compensate for the added load of the compressor. Newer vehicles are controlled by the ECM and will adjust the IAC valve as needed. Either way you will notice a momentary change in engine RPM. Anything more than momentary such as surging will need to be checked out and most likely involves the throttle body.
