Test | Result | Action | |
|---|---|---|---|
1 | Check cable and terminal integrity: - Engine ECM pin B23 - Engine ECM pin A5 - Engine ECM pin B18 - Sensor pin 1, 2, 3 | OK | Disconnect ambient pressure sensor and proceed to test 2 |
Faulty | Rectify fault, proceed to test 5 | ||
2 | Check cable for short circuit to ground: - Engine ECM pin B23 to Engine ECM pin A5 - Engine ECM pin B23 to Engine ECM pin B18 | OK | Proceed to test 3 |
Faulty | Locate and rectify wiring fault, proceed to test 5 | ||
3 | Check cable for short circuit to supply: - Engine ECM pin B18 to Engine ECM pin A5 | OK | Proceed to test 4 |
Short circuit | Locate and rectify wiring fault, proceed to test 5 | ||
4 | Check cable for continuity: - Engine ECM pin B23 to sensor pin 1 - Engine ECM pin A5 to sensor pin 2 - Engine ECM pin B18 to sensor pin 3 | OK | Renew ambient pressure sensor and proceed to test 5 |
Open circuit | Locate and rectify wiring fault, proceed to test 5 | ||
5 | Reconnect harness, clear fault code and run engine. | OK | Action complete - quit test |
