Circuit Description
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.
