- ECM pin B01 to ECM pin B20
3
Disconnect the fol lowing sensors in turn :
- MAP sensor
- Ambient pressure sensor
- Throttle position switch

- ECM pin B01 to A06
- ECM pin B20 to A06
- ECM pin B01 to battery positive
- ECM pin B20 to battery positive
5 Reconnect harness, clear fault code and use OK
service software to check for correct sensor
outputs and 5V sensor supply voltage level
