3. Place ignition switch in OFF
position. Disconnect harness
from throttle position sensor
690 connector (X690).
a. With
accelerator
pedal
released, measure resistance
from pin 2 to pin 3 of 690
connector (X690) at switch
side of connector. Resistance
should be greater than 100k
ohms.
If resistance is not as specified,
replace throttle position sensor
(WP 0061 00).
b. With
accelerator
pedal
released, measure resistance
from pin 2 to pin 1 of 690
connector (X690) at switch
side of connector. Resistance
should be greater than 100k
ohms.
If resistance is not as specified,
replace throttle position sensor
(WP 0061 00).
c. With
accelerator
pedal
depressed,
measure
resistance from pin 3 to pin 1
of 690 connector (X690) at
switch side of connector.
Resistance should be greater
than 100k ohms.
If resistance is not as specified,
replace throttle position sensor
(WP 0061 00).
