Circuit Description

WARNING: This page is about a different variant/trim than selected.

PCM operates a Pulse Width Modulated (PWM) solenoid to control EGR valve. This is a normally open solenoid. During normal operation, PCM compares desired MAF signal with the measured MAF signal and makes corrections in the duty cycle accordingly.

DTC will set when the following conditions are present:

The 5 Adaptive Learn Matrix (ALM) cells are less than 0.5.
