<From 1990 m$ek>-
(5) If there is a deviation from the standard value, loosen the
throttle-position sensor installation bolt and then turn the
throttle-position sensor itself to make the adjustment. Be
sure to securely retighten the bolt after making the
adjustment.
NOTE
The output voltage becomes higher when the throttle-
l
position sensor is turned clockwise.
A diagnostic trouble code for idle speed control motor
l
position sensor may be output when adjusting the
throttle position sensor. The reason is that, when the
throttle position sensor is turned, the throttle position
sensor voltage may differ from the normal voltage dur-
ing idling, but this is no malfunction of the idle speed
control motor position sensor.
(6) Switch OFF the ignition switch.
(7) If a diagnostic trouble code is output when adjusting the
throttle position sensor, use the scan tool and erase the di-
agnostic trouble code or first disconnect the battery (-)
cable from the battery terminal for IO seconds or more and
then reconnect it. (This will erase the memory for the diag-
nostic trouble code due to adjustment of the throttle posi-
tion sensor.)
