Circuit Description
WARNING: This page is about a different car, the 2002 Oldsmobile Intrigue and 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
Powertrain Control Module (PCM) monitors Exhaust Gas Recirculation (EGR) valve pintle position input to ensure valve responds properly to PCM commands. The PCM compares EGR position sensor with desired EGR position when valve is commanded open. If difference between EGR position sensor and desired EGR position is more than 20 percent, this DTC will set.
