Fault Code | Possible cause | Action |
P0113 | Open circuit, or short circuit to battery+ | View & note diagnostic tool "freeze frame" data if available. View & note diagnostic tool "sensor" data. Ensure sensor connector is secure. Disconnect ECM and proceed to pinpoint test 1 |
P0112 | Short circuit to ground | Disconnect sensor and proceed to pinpoint test 6 |
Pinpoint tests
Test | Result | Action |
1 Check cable and terminal integrity: - ECM pin A22 - ECM pin A07 | OK | Proceed to test 2 |
Faulty | Rectify fault, proceed to test 7 | |
2 Check resistance value: - ECM pin A22 to ECM pin A07 (Temperature dependent-see below) | OK | Disconnect temp sensor and proceed to test 6 |
Open circuit | Disconnect temp sensor and proceed to test 3 | |
Short circuit | Disconnect temp sensor and proceed to test 4 | |
3 Check cable continuity: - ECM pin A22 to sensor pin 1 - ECM pin A07 to sensor pin 2 | OK | Proceed to test 5 |
Open circuit | Locate and rectify wiring fault, proceed to test 7 | |
4 Check cable for short circuit: - ECM pin A22 to ECM pin A07 | OK | Proceed to test 5 |
Short circuit | Locate and rectify wiring fault, proceed to test 7 | |
5 Check sensor resistance: - Sensor pin 1 to sensor pin 2 (Temperature dependent-see below) | OK | Proceed to test 7 |
Faulty | Renew temp sensor, proceed to test 7 | |
6 Check cable for short circuit: - ECM pin A22 to ground | OK | Proceed to test 7 |
Short circuit | Locate and rectify wiring fault, proceed to test 7 | |
7 Reconnect harness, clear fault code and run engine to verify fault cleared | OK | Action complete - quit test |

Circuit diagram
If engine is warm, remove sensor and allow time to cool to ambient prior to test.
Resistance data:
Ambient temp | Resistance value |
80°C | 200 to 400Ω |
20°C | 2.35 to 2.65KΩ |
-10°C | 8.50 to 10.25KΩ |
