Circuit Description
WARNING: This page is about a different variant/trim than selected.
EGR flow is controlled by vacuum actuated EGR valve. EGR pulse width modulated solenoid meters vacuum level at EGR valve actuator as commanded by PCM. PCM controls EGR solenoid by providing a ground path.
DTC will set when the following conditions are present:
- PCM requested EGR solenoid on.
- Voltage on EGR solenoid control circuit high (near battery voltage)
- Two consecutive faults detected.
- Conditions are met for 2 seconds.
Or
- PCM requested EGR solenoid off.
- Voltage on EGR solenoid control circuit low (near zero volts)
- Two consecutive faults detected.
- Conditions are met for 2 seconds.
