Circuit Description
WARNING: This page is about a different car, the 1996 Cadillac Seville, 1996 Cadillac Eldorado, and 1996 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
This test monitors TP sensor, engine speed, MAP, EGR flow and A/C clutch status. Engine operation denotes that a large change in manifold pressure must be preceded by a change in engine load due to changes in throttle angle, engine speed, EGR flow or A/C clutch status. If these parameters remain constant and there is a rapid change in MAP value, DTC will set.
