input.
- Switch ignition off.
Note:
The values displayed in display field 3 depend on
the calibration of the Throttle Position (TP)
sensor and do not correspond with the actual
throttle valve opening in degrees. The maximum
displayed value is 90.0 . If the throttle angle value does not increase
uniformly:
- Replace throttle valve control module -J338-.
