How to replace the IAC valve on a Mazda 6?
1. Disconnect the negative battery cable. 2. Disconnect the IAC valve connector. 3. Measure the resistance between the IAC valve terminals using an ohmmeter. If not as specified, replace the IAC valve. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION.) If as specified but the Operation Test is failed, carry out the Circuit Open/Short Inspection. 1.
How to check idle air control in Mazda 6?
Perform the following inspection only when directed. Carry out the Idle Air Control Inspection. (See Idle Air Control System Inspection.) If not as specified, perform the further inspection for the IAC valve. 1. Disconnect the negative battery cable. 2. Disconnect the IAC valve connector. 3.
What’s the best way to remove a IACV valve?
WRX03 has also found success with this screw removal technique: Attach a small pair of vise grips to the heads of the screws, just enough pressure to slightly indent the metal. Turn the vise grips along with turning a phillips-head screwdriver at the same time.
Where is the IACV located on a 2002 My?
Irregular idle conditions may be the result of a dirty IACV sensor. Limited discussion of the IACV is covered on page 36 of the DOHC Engine service manual (at least for the 2002 MY). Where Is The IACV? The IACV sits directly above the throttle body, and is affixed to the throttle body with two screws.

What are the symptoms of an idle air control valve ( IAC )?
Another symptom of a potential issue with the idle air control valve (IAC) is; an illuminated Check Engine Light. If the engine control module detects an issue with the idle air control valve circuit or signal; it will set off the Check Engine Light to notify the driver that there’s an issue.
What should the resistance be on an IAC valve?
Using an ohmmeter, measure the resistance between pins 3 and 2 on the (IAC) valve. Resistance should be 10-14 ohms. If resistance is ok, proceed to the next step. Finally, if resistance is out of range, replace the (IAC) and retest. Using an ohmmeter, measure the resistance between pins 1 and 2 on the (IAC) valve.
