P0208 Injector Circuit Malfunction – Cylinder 8

OBD-II Trouble Code Technical Description

Cylinder 8 Injector Circuit Malfunction

What does that mean?

This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model.

P0208 means that the PCM detected a fault in the injector or the wiring to the injector. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled "low" or close to zero.

When the injector is switched off, the PCM expects to see a voltage that is close to battery voltage or "high". If it doesn’t see the expected voltage the PCM will set this code. The PCM also monitors resitance in the circuit. If the resistance is excessively low or high it will set this code.

Potential Symptoms

The symptoms for this code will likely be a misfire and a rough running engine. Poor acceleration. The MIL will also be illuminated.

Causes

The causes of a P0208 engine light code could be any of the following:

  • Bad injector. This is usually the cause of this code but doesn’t rule out the possibility of one of the other causes
  • Open in the wiring to the injector
  • Short in the wiring to the injector
  • Bad PCM

    • Possible Solutions

  • First, using a DVOM check the resistance of the injector. If it isn’t within specs, then replace the injector.
  • Check for voltage at the fuel injector connector. It should have 10 volts or more.
  • Visually check the connector for damage or broken wires.
  • Visually check the injector for damage.
  • If you have access to an injector tester, activate the injector and see if it operates. If the injector operates, then you likely have either an open in the wiring, or a blocked injector. If you do not have access to a tester, swap the injector with another one and see if the code changes. If the code changes, then change the injector.
  • At the PCM, remove the driver wire from the PCM connector and Ground the wire. (Make sure you have the correct wire. If you’re not sure, do not attempt) The injector should activate
  • Replace the injector

    "Delete Error Code Permanently, Disable DTC Error Code Function for p0208 in the ECU"

    In extreme cases, we even have the option to permanently remove the specific DTC p0208 and disable the function of the specific error code in the ECU. All other fault code functions will then continue to work to protect the engine. This is different from clearing an error code with a diagnostic device. We have the option to permanently remove the function of the specific error code, so that it never comes back. Also emergency running that occurs on the specific error code can be solved in most cases.

    Of course we prefer to first try to solve the cause of the error code, but sometimes the only solution is to permanently disable the DTC function of p0208.
