P0204 on Chrysler
Injector Circuit/Open - Cylinder 4
P0204 on Chrysler vehicles indicates injector circuit/open - cylinder 4. Au7o has documented this code across 1 Chrysler model — most commonly on LeBaron. This code means the Engine Control Module detected an electrical problem (open circuit or out-of-range resistance) in the fuel injector control circuit for cylinder 4. The ECM controls each injector through its own circuit and monitors it to confirm proper operation. P0204 indicates the computer isn't seeing the expected electrical response from cylinder 4's injector, so that cylinder may not be getting the correct fuel. You'll often notice a misfire, rough running, and a loss of power tied to cylinder 4. Typical repair costs on Chrysler range from $100 to $400, depending on the specific model and root cause.
Common Causes of P0204
- •Damaged or corroded injector connector at cylinder 4
- •Open or shorted wiring in the injector control circuit
- •Failed (electrically open) fuel injector on cylinder 4
- •Loose or backed-out connector pin
- •Poor ground or power feed to the injector
- •Faulty injector driver inside the ECM/PCM
- •Chafed harness causing intermittent open
P0204 on Chrysler by Model
Chrysler LeBaron(1 issue)
- Fuel Injector Clogging and Leaking1990-1995
Fuel injectors develop clogs and O-ring leaks from age and fuel deposit buildup. Clogged injectors cause misfires and poor fuel economy. Leaking injector O-rings create a fire hazard from fuel dripping onto the hot engine.
