WARNING: This page is about a different car, the 1991 Acura Legend. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition off. Remove ACG fuse in underdash fuse box for 10 seconds to reset ECU. Start engine, and connect jumper wire to diagnostic connector. Observe CHECK ENGINE light. If light does not flash, problem is intermittent. Test drive, and check again.
- If CHECK ENGINE light flashes Code 13, substitute a known good ECU, and recheck. If condition goes away, replace ECU (PA sensor is built into ECU).
