Set Condition

WARNING: This page is about a different car, the 2025 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

During a slight acceleration condition, the Powertrain Control Module (PCM) turns on the Exhaust Gas Recirculation (EGR) Valve and monitors the reaction of the fuel trim. A fault will set if the expected reaction is not detected.
