P0236 and P0116 Fault Codes on 2007 Dodge 2500 Diesel: Power Loss and Coolant Sensor Issues
2007 Dodge 2500 4x4 Diesel (5.9L, Extended Cab, Automatic), 101,000 miles: Recently purchased this vehicle and today it triggered two diagnostic trouble codes—P0236 (Turbo Charger Boost Pressure Sensor Performance) and P0116 (Engine Coolant Temperature Sensor Performance). I noticed a significant loss of power when climbing hills. The engine temperature gauge reads normally, all fluids are at proper levels, and the battery charging system is functioning correctly. The day was cold but not below freezing. Despite these conditions, the issue persists. Any insights or troubleshooting steps for these specific codes on this model would be greatly appreciated.
This is strange—everything ran normally initially with no engine light or warning signs. It was performing as expected until today. Now what? Any ideas?
