Diagnostic Procedure

  1. If I/M system check has been performed, go to next step. If I/M system check has not been performed, go to INSPECTION/MAINTENANCE SYSTEM CHECK .
  2. Ensure vehicle is operating with conditions for running this procedure. See ENABLE CRITERIA . Turn off all accessories, including A/C and blower fan. Start engine and allow it to idle. Accelerate at part throttle to 45-55 MPH and maintain speed for 6 minutes or until I/M system status updates to YES. Using scan tool, observe I/M system status. If HO2S/O2S system status updated to YES, go to step  5. If HO2S/O2S system status did not update to YES, go to next step.
  3. Using scan tool, observe DTC information. If scan tool indicates any failed DTCs, perform appropriate diagnostic test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS . If scan tool does not indicate any failed DTCs, go to next step.
  4. Using scan tool, observe NOT RAN SINCE CODE CLEARED display to determine if DTCs P0133, P0140, P1133 and P1134 have run. For those DTCs that have not run, operate vehicle under conditions to meet code enable criteria until DTC(s) runs. See CODE ENABLE CRITERIA under appropriate DTC under DIAGNOSTIC TESTS. Using scan tool, observe I/M system status display. If HO2S/O2S system status updated to YES, go to next step. If HO2S/O2S system status did not update to YES, see DIAGNOSTIC AIDS .
