Dodge Nitro 2.8 CRD 2007 - P0262, P0265, P0268, P0271 Fault Codes & Engine Cutout Fix

Model: Dodge Nitro 2.8 crd 2007 Fault Code: P0262 Posted: 2017-03-08 09:53

Hi everyone, new to the forum and in need of urgent help. I own a 2007 Dodge Nitro 2.8L CRD diesel engine, which is currently throwing out multiple OBD-II fault codes: P0262 (Cylinder 1 Injector Circuit High), along with P0265, P0268, and P0271 — each corresponding to the injector circuit pressure being too high in cylinders 2, 3, and 4 respectively. The car runs fine when idling or in 'N' (neutral) mode but cuts out completely after just 100 yards while driving. This happens intermittently, suggesting a wiring or electrical fault rather than mechanical failure. I’ve already consulted an auto electrician, and the diagnosis points to potential issues with injector circuit wiring. The root cause appears to be physical damage to critical wiring harnesses due to rubbing against engine components over time. Any insights into common wiring paths for these codes in 2007 Dodge Nitro CRD models would be greatly appreciated — especially whether the affected wires run near the radiator (front top) or firewall (rear top) of the engine.

The P0262, P0265, P0268, and P0271 codes typically indicate wiring issues between the ECU and fuel injectors. While I don’t currently have a detailed wiring diagram available, I’ve compiled supplementary information for 2.5L and 2.8L CRD models that may help with troubleshooting.

The issue is most likely related to damaged or frayed wiring in the injector circuit harnesses — especially where they run along engine components.

Thanks for the input. The vehicle has now been taken to a professional auto electrician for inspection and repair. I’ll update with the final diagnosis once it’s complete.

Update: The issue was resolved by identifying a main wiring harness from the ECU to the injectors that had been rubbing against an air conditioning pipe. This caused intermittent grounding, leading to all four cylinder injector circuit faults. Additionally, the main live wire from the alternator to the battery also rubbed against the same pipe, resulting in battery drain — fortunately no engine fire occurred.

Hi — I hope you're still monitoring this thread. I experienced exactly the same issue yesterday on my 2007 Dodge Nitro CRD while driving on the autobahn in Germany. All four cylinders showed high injector pressure (P0262, P0265, P0268, P0271) and I was able to keep moving at a maximum speed of 110 km/h by resetting the codes multiple times. I’d like to know which wiring bundle caused your issue — is it the one running along the radiator side (front top) or near the firewall (rear top) of the engine? After returning home, I inspected the harness and found significant wear on black insulating tape and plastic sheathing at several spots after 11 years and 207k km of use. No immediate failure points were visible, but I suspect wire chaffing is a common cause. I’ve also been seeing P0069 codes post-startup, sometimes leading to sputtering and engine cutouts — could this be related to the same wiring degradation? Thanks for any insights — Marco
