MODEL IDENTIFICATION
Description
Several states require that a vehicle pass On-Board Diagnostic (OBD) system tests and I/M emission inspection in order to renew license plates. This is accomplished by viewing the I/M SYSTEM STATUS display on scan tool. Using a scan tool, the technician can observe the I/M System Status in order to verify that vehicle meets the criteria that complies with the local area requirements.
This procedure satisfies enable criteria necessary to execute all monitor diagnostics, and complete trips for those particular diagnostics. When all diagnostic tests have been completed, I/M system status indicators are set to YES. Perform this test when more than one or all I/M system status indicators are set to NO.
The following DTCs are required to set system status to YES
- P0130, P0131 or P0151 - HO2S 1 Circuit (Low Voltage)
- P0132 or P0152 - HO2S 1 Circuit (High Voltage)
- P0133 or P0153 - HO2S Slow Response
- P0134 or P0154 - HO2S 1 Insufficient Activity
- P0135 or P0155 - HO2S 1 Heater Performance
- P0136 - HO2S 2 Circuit
- P0141 - HO2S 2, Bank 1 Heater Performance
- P0161 - HO2S 2, Bank 1 Heater Performance
- P0400 or P0403 - EGR System (2.0L only)
- P0420 or P0430 - Catalyst System
- P0440, P0443 (2.0L only) or P0455 - EVAP System
Diagnose affected DTCs. See DIAGNOSTIC TROUBLE CODE DEFINITIONS .
The purpose of this test is to satisfy the enable criteria necessary to execute I/M readiness diagnostics for the catalyst system. Test may be used to set the I/M System Status indicators to YES.
The purpose of this test is to satisfy the enable criteria necessary to execute I/M readiness diagnostics for the EGR system. The test may be used to set I/M System Status indicators to YES. Ensure that vehicle meets the requirements in Conditions for Running DTC before performing this test. Failure to meet necessary requirements may produce inaccurate test results.
The purpose of this test is to satisfy the enable criteria necessary to execute I/M readiness diagnostics for the Evaporative Emission (EVAP) system. The test may be used to set the I/M System Status indicators to YES.
The purpose of this test is to satisfy the enable criteria necessary to execute I/M readiness diagnostics for the HO2S/O2S system. Test may be used to set the I/M System Status to YES. Ensure vehicle meets the requirements listed in Conditions For Running DTC before performing this test.
The purpose of this test is to satisfy the enable criteria necessary to execute I/M readiness diagnostics for Heated Oxygen Sensor (HO2S) system. The test may be used to set the I/M System Status to YES. Ensure vehicle meets the requirements listed in conditions for running DTC before performing this test.
