DESCRIPTION
- Throttle position sensor
The throttle position sensor detects the throttle valve position and sends a signal to the TCM.
- Throttle position switch
Consists of a wide open throttle position switch and a closed throttle position switch.
The wide open throttle position switch sends a signal to the TCM when the throttle valve is open at least 1/2 of the full throttle position. The closed throttle position switch sends a signal to the TCM when the throttle valve is fully closed.

ON BOARD DIAGNOSIS LOGIC

DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE

CAUTION: Always drive vehicle at a safe speed.

NOTE: If "DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.













With Consult
1. Turn ignition switch "ON" and select "DATA MONITOR" mode for "A/T" .




2. Check the following.
If the check result is NG, go to "DIAGNOSTIC PROCEDURE".
If the check result is OK, go to following step.
3. Turn ignition switch "ON" and select "DATA MONITOR" mode for "ENGINE".
4. Start engine and maintain the following conditions for at least 3 consecutive seconds. Then release accelerator pedal completely.
VHCL SPEED SE: 10 KPH (6 MPH) or more
THRTL POS SEN: Approximately 3 V or less
Selector lever: D position (OD "ON")
If the check result is NG, go to "DIAGNOSTIC PROCEDURE".
If the check result is OK, go to following step.
5. Maintain the following conditions for at least 3 consecutive seconds. Then release accelerator pedal completely.
VHCL SPEED SE: 10 KPH (6 MPH) or more
Accelerator pedal: Wide open throttle
Selector lever: D position (OD "ON")

OR

With Generic Scan Tool
