I turned on my car and received error code 12 and error code 25 today. 12 is not a big issue, as it just means the computer needs reset. But 25 means that Idle air control motor circuits, target idle not reached (+/- 200),vacuum leak found. How would I locate the Idle Air Control to inspect and/or replace it, and how do I look for a vacuum leak? Thank you!
Come on people ur going to confuse him. the iac and tps are on the same side of the throttle body. the tps is directly across from the throttle rotor assem. the IACis just up on the throttle body
the IAC is on the throttle body and you look for leaks by listening for it or putting water or gas on the hose and look for where it starts to disappear.
this is located on the throttle physique. word throttle place sensor is inline opposite the throttle cable, the idle administration motor is the different device bolted to physique casting.
The IAC motor is mounted on the side of the throttle body. There are 2 torx screws holding it on. Check for vacuum leaks by carefully looking at the rubber lines (about 4-5) running from the intake manifold. Look for split or cracked lines and replace them. You can also check Autozone's website for diagrams. Good luck.
The idle air control motor is on the throttle body. This where the throttle cable connects to the engine. The idle air control should be opposite the throttle cable. There will be a wire harness connected to it. You can replace it by unplugging it and removing a few screws. The idle air control is what adjusts the amount of air going into the engine at idle and controls idle speed. You may have a vacuum leak, but replacing the idle air control should fix it. You can check for a vacuum leak by spraying carburetor cleaner on vacuum hoses and around the throttle body and where the intake manifold bolts to the head. If the engine speed picks up where you are spraying, you have found the vacuum leak.
