Fault Code | Possible cause | Action |
|---|---|---|
P0120 | Throttle position sensor 1 short circuit to battery positive or open circuit | View and note diagnostic software 'freeze-frame' data if available. View and note diagnostic software 'sensor' data. Make sure the throttle position sensor connector is secure. Disconnect engine ECM and proceed to pinpoint test 1: |
P0121 | Throttle position sensor 1 signal out of range | |
P0122 | Throttle position sensor 1 short circuit to ground | |
P0220 | Throttle position sensor 2 short circuit to battery positive or open circuit | |
P0221 | Throttle position sensor 2 signal out of range | |
P0222 | Throttle position sensor 2 short circuit to ground | |
P2135 | Throttle position sensor 1 correlation error with throttle position sensor 2 |

Test | Result | Action | |
|---|---|---|---|
1 | Check cable and terminal integrity: - Engine ECM pin A20 - Engine ECM pin A38 - Engine ECM pin A26 - Engine ECM pin A32 | OK | Disconnect sensor and proceed to test 2 |
Faulty | Rectify fault, proceed to test 5 | ||
2 | Check cable for short circuit: - Engine ECM pin A26 to ground - Engine ECM pin A38 to ground | OK | Proceed to test 3 |
Short circuit | Locate and rectify wiring fault, proceed to test 5 | ||
3 | Check cable continuity: - Engine ECM pin A32 to throttle position sensor connector pin 5 - Engine ECM pin A38 to throttle position sensor connector pin 4 - Engine ECM pin A20 to throttle position sensor connector pin 3 - Engine ECM pin A26 to throttle position sensor connector pin 6 | OK | Proceed to test 4 |
Open circuit | Locate and rectify wiring fault, proceed to test 5 | ||
4 | Check cable for short circuit: - Engine ECM pin A26 to Engine ECM pin A32 - Engine ECM pin A26 to Engine ECM pin A38 - Engine ECM pin A32 to Engine ECM pin A38 | OK | Renew throttle position sensor, proceed to test 5 |
Short circuit | Locate and rectify wiring fault, proceed to test 5 | ||
5 | Reconnect harness, clear fault code and run engine to verify fault cleared. | OK | Action complete - quit test |
Fault still present | Contact Triumph service | ||
