CIRCUIT DESCRIPTION
The fuel injector is a solenoid operated device. The fuel injectors receive 12 volts from the ignition switch through a fuse. The PCM provides the ground path for each injector through individual driver circuits. The PCM monitors the circuits for proper voltage levels. When an improper voltage level occurs, the driver signals the PCM. If the PCM detects an improper voltage level in the fuel injector circuit for cylinder #8, DTC P0208 will set.

CONDITIONS FOR RUNNING THE DTC
^ No system voltage DTCs are set.
^ System voltage between 11-16 volts.

CONDITIONS FOR SETTING THE DTC
The PCM detects an improper voltage level in the fuel injector circuit for cylinder #8.

ACTION TAKEN WHEN THE DTC SETS
^ The PCM will illuminate the Malfunction Indicator Lamp (MIL) the first time the malfunction is detected.
^ The PCM will store conditions which were present when the DTC set as Freeze Frame and Fail Records data.

CONDITIONS FOR CLEARING THE MIL/DTC
^ The PCM will turn the MIL OFF during the third consecutive trip in which the diagnostic has been run and passed.
^ The History DTC will clear after 40 consecutive warm-up cycles have occurred without a malfunction.
^ The DTC can be cleared by using the scan tool Clear DTC Information function.

DIAGNOSTIC AIDS
If the condition is intermittent, refer to Intermittent Conditions in Symptoms. Intermittent Conditions

TEST DESCRIPTION
The numbers below refer to the step numbers on the diagnostic table.
4. This step tests for voltage at the fuel injector harness connector. The INJ fuse supplies power to the coil side of the fuel injector harness connector. If the fuse is open, a short to ground on the fuel injector B+ supply circuit is indicated.
5. This step verifies that the PCM is able to control the fuel injector. If the test lamp blinks, then the PCM and wiring are OK.
6. This step tests if a ground is constantly being applied to the fuel injector.
