Ignition Control (IC) Timing Advance System

WARNING: This page is about a different car, the 1997 Pontiac Sunfire and 1997 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.

A malfunction in the IC circuit (formerly referred to as the EST circuit) will cause PCM to turn on Malfunction Indicator Light (MIL) and confirm fault by setting a related diagnostic trouble code. Refer to the TESTS W/CODES - 2.4L article.
