Fault Code | Possible cause | Action |
P0113 | Open circuit, or short circuit to battery+ | View & note diagnostic software 'freeze frame' data if available. View & note diagnostic software '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 A11 ECM pin B20 | OK | Proceed to test 2 |
Faulty | Rectify fault, proceed to test 7 | |
2. Check resistance value: - ECM pin A 11 to ECM pin B20 (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 A 11 to sensor pin 1 ECM pin B20 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 A 11 to ECM pin B20 | 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 A 11 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 |
Fault still present | Contact Triumph service |
Circuit Diagram
If engine is warm, remove sensor and allow time to cool to ambient prior to test.
