Engine General Information and Diagnosis: Bi-Fuel LPG model 1A-80
Wiring Diagram
Circuit Description
When the ignition switch is turned to ON position, the main relay turns ON (the contact point closes) and the main
power is supplied to ECM. And then ECM supplies 5 V power to each sensor (A/C refrigerant pressure sensor, MAP
sensor and TP sensor).
