Failure in the coil drive – VB027;
Pump drive failure – CA3262;
Map power failure – Cl 33072 (8-pin tsop)
Note:Some vehicles may show oscillation idle speed due to voltage instability (battery or alternator) and suspect a plant defect.
Drive CA 3262 AE – Relay A / C – Relay Fuel pump
This component works similarly to NPN transistors , that is, the input (trip) is made by positive 5 volts and the output is negative.
Ignition coil drive – VB 027
Stepper motor drive – L 9122
