If N.G., replace throttle sensor.

If throttle sensor is replaced or removed, it is necessary to install in proper position, by following the procedure as shown below:

1
Install throttle sensor body in throttle chamber. Do not tighten bolts. Leave bolts loose.
2
Connect throttle sensor and idle switch harness connector.
3
Start engine and warm it up sufficiently.
4
Perform "THROTTLE SEN ADJ" in "WORK SUPPORT" mode. Measure output voltage of throttle sensor using voltmeter.
SEF561K
5
Adjust by rotating throttle sensor body so that output voltage is 0.45 to 0.55V.
SEF760K
6
Tighten mounting bolts.
7
Disconnect throttle sensor harness connector for a few seconds and then reconnect it.
