Is DTC P0201, P0202, P0203, or P0204 indicated?
YES : Check for poor connections or loose terminals at the injector and the PCM. If the PCM was updated,
substitute a known-good PCM See PCM UPDATE or PCM REMOVAL AND INSTALLATION , then
recheck. If the PCM was substituted, go to step 1.
NO : Troubleshooting is complete. If the PCM was substituted, replace the original PCM See PCM UPDATE
or PCM REMOVAL AND INSTALLATION . If any other Pending or Confirmed DTCs are indicated, go to
the indicated DTC's troubleshooting.
