Common defects:

Failure in the stepper motor drive – L9122;

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
