Fault Code | Possible cause | Action |
P0222 | 2nd throttle position sensor low voltage, (short circuit to ground or open circuit) | View & note "freeze frame" data if available. View & note "sensor" data. Ensure sensor connector is secure. Disconnect ECM and proceed to pinpoint test 1 |
P0223 | 2nd throttle position sensor high voltage, (short circuit to sensor supply) |
Pinpoint tests
Test | Result | Action |
1 Check cable and terminal integrity: - ECM pin A01 - ECM pin A07 - ECM pin A02 | OK | Disconnect sensor and proceed to test 2 |
Faulty | Rectify fault, proceed to test 5 | |
2 Check cable for short circuit: - ECM pin A02 to ground | OK | Proceed to test 3 |
Short circuit | Locate and rectify wiring fault, proceed to test 5 | |
3 Check cable continuity: - ECM pin A01 to sensor pin 1 - ECM pin A07 to sensor pin 2 - ECM pin A02 to sensor pin 3 | OK | Proceed to test 4 |
Open circuit | Locate and rectify wiring fault, proceed to test 5 | |
4 Check cable for short circuit: - ECM pin A02 to ECM pin A01 - ECM pin A02 to ECM pin A07 | OK | Renew 2nd throttle position sensor and proceed to test 5 |
Short circuit | Locate and rectify wiring fault, proceed to test 5 | |
5 Reconnect harness, clear fault code. | OK | Action complete, quit test |
