DETECTED FAILURE CONDITION
The signal does not reach ECU for more than 2 sec. after
receiving the IAP signal.
Pick-up coil wiring and mechanical parts.
(Pick-up coil, lead wire coupler connection)
The sensor should produce following voltage.
0.2 V � sensor voltage � 4.8 V
Without the above range for 5 sec. and more, C14 is indicated.
Throttle position sensor, lead wire / coupler connection.
The sensor voltage should be the following.
0.2 V � sensor voltage � 4.6 V
Without the above range for 5 sec. and more, C15 is indicated.
Water temperature sensor, lead wire / coupler connection.
The sensor should produce following voltage.
0.2 V � sensor voltage � 4.8 V
Without the above range for 5 sec. and more, C17 or C18 is
indicated.
Intake air pressure sensor, lead wire / coupler connection.
The sensor voltage should be the following.
0.2 V � sensor voltage � 4.6 V
