DETECTED FAILURE CONDITION
When no actuator control signal is supplied from the ECM or
communication signal does not reach ECM or operation voltage
does not reach STVA motor, C28 is indicated. STVA can not
STVA lead wire/coupler.
The sensor should produce following voltage.
sensor voltage < 4.85 V
Without the above value, C29 is indicated.
Secondary throttle position sensor, lead wire/coupler connec-
Gear position signal
Gear position signal voltage should be higher than the following
for 3 seconds and more.
(Gear position sensor voltage> 0.6 V)
Without the above value, C31 is indicated.
Gear position sensor, wiring/coupler connection. Gearshift cam
Crankshaft position sensor (pickup coil) signal is produced, but
fuel injector signal is interrupted continuous by 4 times or more.
In this case, the code C24, C25, C26 or C27 is indicated.
Injector, wiring/coupler connection, power supply to the injector.
Fuel pump relay
No voltage is applied to the fuel pump, although fuel pump relay
is turned ON, or voltage is applied to fuel pump although fuel
pump relay is turned OFF.
Fuel pump relay, connecting lead wire, power source to fuel
pump relay, fuel injectors.
Ignition switch signal is not input in ECM.
Ignition switch, lead wire/coupler.
Exhaust control valve
EXCVA position sensor produces following voltage.
Without the above value, C46 is indicated. EXCVA motor can
EXCVA, EXCVA adjustment, lead wire/coupler.
