2003 Dodge Durango 4.7L Engine P0123, P0113, and P0108 Fault Codes - Causes and Fixes

Model: 2003 dodge durango Fault Code: P0108 Posted: 2012-01-11 01:05

My 2003 Dodge Durango with a 4.7L engine has reached 110,000 miles. After picking it up from the dealership, I noticed the vehicle was running roughly, as if only three cylinders were firing. The OBD2 scanner initially showed only one code: P0123. I replaced the throttle position sensor (TPS), but after installation, the engine still ran poorly with no power. When I reconnected the scanner, it now displays three codes: P0123, P0113, and P0108. Is it normal for all three of these fault codes to appear simultaneously? Or is there another underlying issue causing this? The fact that the same code (P0123) persists after replacing the TPS suggests a deeper problem—could it be related to wiring or sensor interference? I'm looking for expert insight on what might be causing these errors and how to resolve them. Any help would be greatly appreciated. Thanks, Mike
