P1129 Chrysler - Closed Loop Fueling Not Achieved Bank 2
- Engine Coolant Temperature (ECT) sensor or wiring connectors
- MAP sensor or wiring connectors
- O2 sensor wiring or connectors
- Engine mechanical system
The Powertrain Control Module (PCM) detects a condition where the vehicle has remained in open loop fuel control ,from a start-up condition ,longer than a calibrated amount of time ,when conditions would have otherwise closed loop operation.
Any information is appreciated. Thanks
