DIAGNOSIS CODE NO. 13
CAM ANGLE SENSOR & CIRCUIT
When no cam angle sensor signal is inputted within 2 sec-
onds while the engine is being cranked by the starter
motor.
1. Check of cam angle sensor
(1) Disconnect the connector of the cam angle sensor.
(2) Check that there is the specified resistance between
the respective terminals of the cam angle sensor.
Specified Value:
NOTE:
•
If the resistance will not conform to the specification,
replace the signal generator. Refer to the IG section.
(3) Temporarily remove the EFI main relay at the relay box.
(4) Check that there is a voltage between the terminals of
the cam angle sensor when the engine is being
cranked.
Specified Value:
NOTE:
•
The generating voltage should be measured, using the
AC range of a volt meter.
•
If the measured value does not conform to the specifi-
cation, adjust the gap. See the IG section.
