DTC P0130 - Front Oxygen (O2) Sensor
- Check Input Signal Circuit (California Only)
Turn ignition switch to OFF position. Disconnect front heated O2 sensor harness connector and ECM harness connector. See Figure and Figure . Using an ohmmeter, check continuity between ECM harness connector terminal No. 46 and front heated O2 sensor harness connector terminal No. 2 (White wire). See Figure. If no continuity exists, repair open White wire. If continuity exists, check continuity between ECM terminal No. 46 (White wire) and ground. If continuity exists, repair short in White wire. If no continuity exists, go to next step. - Clear Self-Learning Data (California Only)
Turn ignition switch to OFF position. Loosen and retighten engine ground screws. Disconnect MAF sensor harness connector. See Figure. Restart and run engine for at least 3 seconds at idle. Stop engine and reconnect MAF sensor harness connector. Verify DTC P0100 is displayed. Erase memory and verify DTC P0000 is displayed. Restart engine and run for at least 10 minutes at idle. If DTCs P0171 or P0172 are detected and engine is difficult to start, see:- DTC P0171 - FUEL INJECTION SYSTEM FUNCTION - LEAN SIDE (CALIF. ONLY) or
- DTC P0172 - FUEL INJECTION SYSTEM FUNCTION - RICH SIDE (CALIFORNIA ONLY).
If DTCs P0171 or P0172 are not detected and it is not difficult to start engine, go to next step.
- Check Component (California Only)
Inspect front heated O2 sensor. See procedures in the SYSTEM/COMPONENT TESTS article. Replace front heated O2 sensor as required. Disconnect and reconnect harness connectors in circuit and perform FINAL CHECK . - Check Input Signal Circuit (Non-California)
Turn ignition switch to OFF position. Disconnect front O2 sensor harness connector and ECM harness connector. See Figure and Fig 1 . Using an ohmmeter, check continuity between ECM harness connector terminal No. 46 and front O2 sensor harness connector terminal No. 1 (White wire). See Figure. If no continuity exists, repair open White wire. If continuity exists, check continuity between ECM terminal No. 46 (White wire) and ground. If continuity exists, repair short in White wire. If no continuity exists, go to next step. - Clear Self-Learning Data (Non-California)
Turn ignition switch to OFF position. Loosen and retighten engine ground screws. Disconnect MAF sensor harness connector. See Figure. Restart and run engine for at least 3 seconds at idle. Stop engine and reconnect MAF sensor harness connector. Verify DTC P0100 is displayed. Erase memory and verify DTC P0000 is displayed. Restart engine and run for at least 10 minutes at idle. If DTC P0170 is detected and engine is difficult to start, see DTC P0170 - FUEL INJECTION SYSTEM . If DTC P0170 is not detected and it is not difficult to start engine, go to next step. - Check Component (Non-California)
Inspect front O2 sensor. See SYSTEM/COMPONENT TESTS article. Replace front O2 sensor as required. Disconnect and reconnect harness connectors in circuit and perform FINAL CHECK .
