Fault Code | Possible cause | Action |
P0201102/03 | Injection system fault - injector 112/3 Misfire indicates open circuit Flooding indicates short circuit | View & note diagnostic software 'freeze frame' data if available. Ensure relevant injector connector is secure. Disconnect ECM and proceed to pinpoint test 1: |
Pinpoint Tests
Test | Result | Action |
1. Check cable and terminal integrity: ECM pin A15 ECM pin A14 ECM pin A13 | OK | Proceed to test 2 |
Faulty | Rectify fault, proceed to test 7 | |
2. Check resistance value: ECM pin A06 to ECM pin A15 (injector 1) ECM pin A06 to ECM pin A14 (injector 2) ECM pin A06 to ECM pin A13 (injector 3) | 11.0 Ω to 12.5 Ω | Proceed to test 3 |
Open circuit | Disconnect relevant injector and proceed to test 4 | |
Short circuit | Disconnect relevant injector and proceed to test 5 | |
3. Check cable for short circuit to ground: ECM pin A 15 to earth ECM pin A 14 to earth ECM pin A 13 to earth | OK | Proceed to test 7 |
Short circuit | Locate and rectify wiring fault, proceed to test 7 | |
4. Check cable continuity: ECM pin A06 to relevant injector pin 2 ECM pin A15 to injector 1 pin 1 ECM pin A 14 to injector 2 pin 1 ECM pin A13 to injector 3 pin 1 | OK | Proceed to test 6 |
Open circuit | Locate and rectify wiring fault, proceed to test 7 | |
5. Check cable for short circuit to supply box: ECM pin A06 to ECM pin A 15 (inj 1) ECM pin A06 to ECM pin A14 (inj 2) ECM pin A06 to ECM pin A13 (inj 3) | OK | Proceed to test 6 |
Short circuit | Locate and rectify wiring fault, proceed to test 7 | |
6. Check relevant injector resistance: Injector pin 1 to injector pin 2 | 11.0 Ω to 12.5 Ω | Proceed to test 7 |
Faulty | Renew relevant injector, proceed to test 7 | |
7. Reconnect harness, clear fault code and run engine to verify fault cleared | OK | Action complete - quit test |
