System Operation
WARNING: This page is about a different car, the 1997 Mazda B2300. However, it is still accessible from the selected car via links, so may be relevant.
To improve idle and driveability performance, PCM cancels air conditioning operation momentarily immediately after starting engine, during wide open throttle or if engine overheats. Faults in A/C cutoff system or circuit should set a diagnostic trouble code. See TESTS W/CODES article.
