CONTROL SYSTEM — Throttle Position Sensor Adjustment / Replacement

F2-151prose procedure

Adjustment

NOTE

The throttle adjusting screw is set at the factory and must not be adjusted. Any adjustment will negatively effect the engine performance.

1
Turn the ignition switch to OFF and the throttle valve to the closed throttle position.
2
Disconnect the throttle position sensor connector.
3
Loosen the throttle position sensor screws.
4
Rotate the throttle position sensor and adjust continuity between the sensor terminals C and D as shown.
5
Tighten the throttle position sensor screws. Tightening torque: 1.6—2.3 N·m {16—24 kgf·cm, 14—20 in·lbf}

Clearance	Continuity
0.15 mm {0.006 in}	Yes
0.50 mm {0.020 in}	No

0.15 mm {0.006 in}

ContinuityYes

0.50 mm {0.020 in}

1
Remove the ECM. (Refer to page F2-141.)
2
Connect the SSTs to the ECM connector as shown.
3
Verify that the throttle valve is at the closed throttle position.
4
Loosen the attaching screws.
5
Turn the ignition switch to ON.
6
Measure the ECM terminal 2F voltage.
7
Adjust the voltage to the specification. Specification: Closed throttle position: 0.1—1.1V; Wide open throttle: 2.8—4.5V (Verify that the voltage increase is directly proportioned to the throttle valve opening angle.)
8
Tighten the attaching screws. Tightening torque: 1.6—2.3 N·m {16—24 kgf·cm, 14—20 in·lbf}
9
If not adjusted, replace the throttle position sensor.
