The idle speed control solenoid step should be the following. Without the above range, C27 is indicated

Idle speed control solenoid, lead wire / coupler connection.

 

C32 / C33

Fuel injector, NO.1 / NO.2

The fuel injector not comes in voltage from the battery, C32 or C33 is indicated.

Injector, wiring / coupler connection, power supply to the injector.

 

C37

Secondary air valve solenoid (SAV solenoid)

When the secondary air valve solenoid voltage is not input in ECU, C37 is indicated

Secondary air valve solenoid, lead wire / coupler connection

 

C41

Fuel pump relay

No voltage is applied to the both injectors 3 for 3 sec. after the contact of fuel pump relay is turned “ON” position. Or voltage is applied to the both injectors, when the contact of fuel pump is “OFF” position

Fuel pump relay, connecting lead wire, power source to fuel pump relay, fuel injector.
