2000 Dodge Durango P0204 Code: Diagnosis and Fix
The P0204 diagnostic trouble code in a 2000 Dodge Durango indicates a fuel injector circuit fault on cylinder 4. This issue can lead to poor engine performance, misfires, or difficulty starting. After consulting with a technician, the root cause was identified as a damaged Powertrain Control Module (PCM). The PCM required replacement, which resolved the P0204 code and restored normal engine operation.
I returned to the dealer this morning and the vehicle is running smoothly now. Thanks for your help—this fixed the issue.
