Diagnostic Procedures

  1. Connect scan tool. Start and operate engine for one minute. Using scan tool, check if DTC is active. If DTC is active, go to next step. If DTC is not active, problem is intermittent. See DIAGNOSTIC AIDS.
  2. If engine misfire is present, diagnose using misfire DTC(s) test, then retest for DTC P0341. If engine misfire is not present, go to next step.
  3. Turn ignition off. Disconnect PCM harness connector J3 and remove cylinder No. 4 signal circuit from PCM harness connector. Reconnect PCM harness connector. Start and operate engine for one minute. If DTC P0341 resets, replace PCM. If DTC P0341 does not reset, go to next step.
  4. Turn ignition off. Disconnect EI module harness connector. Check resistance between cylinder No. 4 signal circuit and ground. If circuit is not open, repair short to ground in circuit. If circuit is open, check for intermittent short to ground in circuit. If circuit is not shorted, replace EI module.
