That is if the ´91 EGR has a switch, or were you not referring to that. I have a ´91 and mine does not have the switch, the earlier model years had the switch. It´s ECM controlled. This is from my FSM. EGR circuit description, brief, With the ign. "ON" engine stopped, the EGR solenoid is de-energized and by grounding the diagnostic "test" terminal, the solenoid is energized. The ECM will check EGR operation when: *Vehicle speed is above 30 MPH, *Manifold absolute pressure is between 15 kPa and 70 kPa, *TPS is between 8% and 30%, *No more than .4% change in TPS. |
