Exhaust Gas RECIRCULATION (C-7): Notes

There are 3 types of EGR systems used: pulse width modulated backpressure EGR (positive and negative) with a control solenoid, pulse width modulated backpressure (positive and negative) EGR without a control solenoid, and digital EGR. To determine EGR system usage, see EGR SYSTEM IDENTIFICATION table.
