What does P0208 mean?
Each fuel injector is an electric valve that the computer opens many times a second. This code means the computer saw an electrical problem in the circuit for the cylinder 8 injector.
The computer tried to control the part and saw an electrical fault, usually an open circuit.
Codes are a starting point. They tell you which test failed, not which part to replace. Check for other stored codes and fix those in a sensible order.
Symptoms
- Check engine light
- Misfire on that cylinder
- Rough idle
- Loss of power
Common causes
- Open circuit in the solenoid or its wiring
- Unplugged or corroded connector
- Blown fuse feeding the component
- Failed component
How to diagnose P0208
- Check the fuse that feeds the component.
- Measure the component's resistance and compare it with the service spec.
- Check for power at the connector with the key on, and for a broken control wire back to the computer.
- Measure the injector's resistance and compare with spec (many gasoline port injectors are about 11-18 ohms).
- Use a noid light to see if the computer is pulsing the injector.
How to fix it
- Repair wiring or connector
- Replace the injector
Estimated repair cost
Likely repairs for P0208 run from about $100 to $600, depending on the cause.
| Repair | Typical range (parts + labor) |
|---|---|
| Diagnostic fee (scan + testing) | $100 - $200 |
| Wiring/connector repair | $100 - $400 |
| Fuel injector replacement (gasoline, one) | $200 - $600 |
These are rough US estimates for an independent shop in 2026, based on typical parts prices and standard labor times. Dealers, big trucks, luxury brands and high-cost areas often run higher. They are not quotes. Use the repair cost estimator to adjust for your vehicle.
How serious is P0208?
High severity
Expect a misfire. Short trips are possible, but get it fixed soon to protect the catalytic converter.
