P0208 Fault Code

P0208 OBD-II Trouble Code Short Description

Cylinder 8 Injector Circuit Malfunction

What does trouble code P0208 mean?

The P0208 fault code indicates a problem with the fuel injector circuit in cylinder 8 of a car's engine. This could be caused by a malfunctioning fuel injector, a wiring issue, or a problem with the engine control module (ECM).

To fix this issue, the fuel injector in cylinder 8 should be inspected and replaced if necessary. The wiring in the fuel injector circuit should also be checked for any damage or connection issues. If the problem persists, the ECM may need to be replaced.

It is important to address this issue promptly, as a malfunctioning fuel injector can lead to poor engine performance, decreased fuel efficiency, and potential engine damage.


What are the symptoms of the P0208 code?

The P0208 fault code typically indicates an issue with the fuel injector circuit for cylinder 8 in a vehicle's engine. This can result in a variety of symptoms, including:

  • Rough idling: The engine may idle inconsistently, causing the vehicle to vibrate or shake.
  • Poor performance: The vehicle may accelerate slowly or struggle to maintain speed while driving.
  • Misfires: The engine may misfire or sputter, resulting in reduced power and efficiency.
  • Increased fuel consumption: If the injector is delivering too much fuel, the vehicle may burn through fuel more quickly than usual.
  • Check engine light: The P0208 code will trigger the check engine light, notifying the driver that there is an issue with the fuel injector circuit.

If left unresolved, the P0208 fault code can lead to more serious engine problems. It is recommended to have the vehicle


What causes the P0208 code?

P0208 is a fault code that indicates a problem in the fuel injector circuit of an engine's cylinder 8. This code is typically found in cars that have an electronic fuel injection system.

The possible causes of a P0208 fault code include a faulty fuel injector, a damaged or dirty wiring harness, a faulty fuel injector driver circuit in the engine control module (ECM), or a malfunctioning fuel injector driver circuit inside the ECM.

To diagnose and fix the problem, a technician will need to conduct a series of tests including a visual inspection of wiring connections and components, testing the fuel injector resistance, and checking for any fault codes stored in the engine control module. Once the cause of the problem is identified, repairs may involve repairing or replacing damaged wiring, replacing the fuel injector, or repairing or replacing the ECM.

Possible Solutions

How to fix P0208?

P0208 is a code that indicates an issue with cylinder 8 injector circuit. It can cause your car's engine to misfire, decrease fuel efficiency, and other performance problems. Here are the steps to fix the P0208 fault code:

  1. Check the Injector First, check the cylinder 8 injector for any clogs or damages that could be causing an issue. If the injector is damaged, replace it with a new one.

  2. Inspect Wiring Check for any damages or breaks in the cylinder 8 injector's wiring harness. If there are any damages, repair or replace the wiring.

  3. Test the Injector Circuit Check the circuit with a multimeter to see if there is a problem with the electrical connection. You should see resistance between the fuel injector and the Engine Control Module (ECM). If there's no resistance, there may be an issue with the wiring, or the injector circuit is open. In this case, repair or replace as necessary.

  4. Check ECM Check the ECM for any damages or problems that could be causing the P0208 code. If you have done all of the above steps and the fault code still appears, the ECM may be the problem. Have it scanned and diagnosed by a professional.

By following these steps, you can resolve the P0208 fault code issue and ensure that your car engine is running smoothly.


  • What is P0208?

    P0208 is a diagnostic trouble code (DTC) that indicates a malfunction in one of the fuel injector circuits in cylinder 8.

  • What are the symptoms of P0208?

    Symptoms of P0208 may include engine misfires, rough idling, decreased fuel efficiency, and the illumination of the check engine light.

  • What causes P0208?

    P0208 can be caused by a variety of factors, including faulty fuel injectors, wiring issues in the fuel injector circuit, or a malfunctioning engine control module (ECM).

  • How is P0208 diagnosed?

    P0208 can be diagnosed using a scan tool that reads DTCs and provides information about the specific malfunction. A mechanic will typically test each fuel injector and check the wiring and connectors to determine the root cause of the issue.

  • Can P0208 be fixed?

    Yes, P0208 can be fixed. Depending on the cause of the issue, a mechanic may replace the faulty fuel injector, repair wiring or connections, or replace the ECM.

  • Is it safe to drive with P0208?

    It is generally not recommended to drive with a P0208 DTC as it indicates a problem with one or more fuel injectors and can lead to further engine damage.

  • How much does it cost to fix P0208?

    The cost to fix P0208 will vary depending on the root cause of the issue. It could range from a simple wiring repair costing a few hundred dollars to replacing multiple fuel injectors and an ECM costing upwards of $1000.

  • Can I clear P0208 code by disconnecting the battery?

    While disconnecting the battery may temporarily clear the DTC, it will not fix the underlying issue causing the code. It is recommended to diagnose and repair the issue instead of simply clearing the code.
