Throttle Position Sensor: Adjustments

If throttle position sensor, closed throttle position switch and/or wide open throttle position switch is replaced or removed, it is necessary to install in proper position, by following the procedure.




1. Install throttle position sensor body in throttle body. Do not tighten bolts. Leave bolts loose.
2. Connect throttle position sensor and closed throttle position switch harness connector.
3. Start engine and warm it up sufficiently.
4. Disconnect IACV-AAC valve sub-harness connector.
5. Disconnect closed throttle position switch harness connector.
6. Check closed throttle position switch OFF - ON speed with circuit tester, closing throttle valve manually.

M/T: Idle speed +250 ±150 rpm
A/T: Engine speed (at idle in "N" position) +250 ±150 rpm




7. If NG, set closed throttle position switch OFF - ON speed to the specified value by turning throttle position sensor body. Connect circuit tester with terminals (a) and (b) on closed throttle position switch side and find out OFF - ON point.
8. Tighten throttle position sensor installing bolts carefully after setting so that throttle position sensor does not move.
