DTC P1705 THROTTLE POSITION SENSORDescription
- Throttle position sensor
The throttle position sensor detects the throttle valve position Q] 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 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.

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-II
1) Turn ignition switch ON and select "DATA MONITOR" mode for "A/T" with CONSULT-II.
2) Apply vacuum to the throttle opener, then check the following. Refer to step 1 and step 2 of "Preparation", "TCM SELF-DIAGNOSIS PROCEDURE (NO TOOLS)".
If the check result is NG, go to "DIAGNOSTIC PROCEDURE", AT-183.
If the check result is OK, go to following step.
3) Turn ignition switch ON and select "DATA MONITOR" mode for "ENGINE" with CONSULT-II.
4) Start engine and maintain the following conditions for at least 3 consecutive seconds. Then release accelerator pedal completely.
VHCL SPEED SE: 10 km/h (6 MPH) or more
THRTL POS SEN: Approximately 3 Volts or less
Selector lever: D position (O/D ON)
If the check result is NO, go to "DIAGNOSTIC PROCEDURE AT-1 83.
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.
