P0201 on Chrysler by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Rough idle
- Misfires
- Fuel smell from engine bay
- Poor fuel economy
How to Fix
Clean or replace fuel injectors. Professional ultrasonic cleaning restores most clogged injectors. Replace all injector O-rings with Viton (fuel-resistant) O-rings. Use fuel injector cleaner additive periodically as preventive maintenance.

Frequently asked questions
What does P0201 mean on a Chrysler?
P0201 stands for "Injector Circuit/Open - Cylinder 1." P0201 means the engine computer detected an electrical problem in the wiring or control circuit for the fuel injector on cylinder 1. The PCM pulses each injector open and back ground, and when it sees an open circuit, a short, or abnormal resistance on cylinder 1's injector circuit, it sets this code. In practice it means cylinder 1 may not be getting fuel injected properly, which can cause a misfire, rough running, or a no-start on that cylinder. It points to the injector itself or its wiring, not to a fuel-pressure problem affecting the whole engine. On Chrysler it is documented across 1 model: LeBaron.
What are the most common causes of P0201?
The most common causes of P0201 are: Damaged or corroded injector connector or terminals at cylinder 1, Broken, chafed, or shorted injector wiring harness, Failed (open or shorted) fuel injector on cylinder 1, Loose or poor ground/power feed to the injector circuit, Blown injector fuse or relay feeding the bank, Failed injector driver inside the PCM/ECM. The specific cause varies by vehicle.
How much does it cost to fix P0201 on a Chrysler?
Published repair estimates on Chrysler range from $100 to $400 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
