TP Sensor Adjustment
NOTE:
Ensure basic idle speed is set to specification before adjusting TP sensor. See BASIC IDLE SPEED
under IDLE SPEED & MIXTURE. Perform all adjustments with engine at normal operating temperature, front wheels in straight-ahead position, cooling fan and all accessories off, and transmission in Park or Neutral.
- TP sensor is not adjustable. Disconnect TP sensor connector. Using external ohmmeter, measure resistance between TP sensor terminals No. 1 and 3. See Fig 1 . If resistance is not 3500-6500 ohms, replace TP sensor.
- While slowly rotating throttle valve from idle to full open, measure resistance between TP sensor terminals No. 2 and 3. If resistance does not change smoothly in proportion to throttle opening, replace TP sensor.
