2. Place ignition switch to OFF
position
and
disconnect
harness from throttle position
sensor. Perform the following
resistance checks.
a. Measure
resistance
between pin 4 and pin 5 of
throttle position sensor
connector
690
(X690)
when accelerator pedal is
depressed and released.
Resistance
should
be
greater
than
250-3000
ohms.
If resistance is not as specified,
replace throttle position sensor
(WP 0061 00).
b. Measure
resistance
between pin 5 and pin 6 of
throttle position sensor
connector
690
(X690)
when accelerator pedal is
depressed and released.
Resistance should be 250-
1500 ohms with pedal
depressed and 3000 ohms
with pedal released.
If resistance is not as specified,
replace throttle position sensor
(WP 0061 00).
NOTE
The difference between resistance readings
should be at least 1000 ohms.
