Accelerator Pedal Position Sensor: Customer Interest
A/T - Driveability Concerns

Number: 97-40-031

Group: TRANSAXLE

Date: SEPTEMBER, 1997

Subject: TRANSAXLE DRIVEABILITY (REFERENCE TO ACCELERATOR SWITCH, TPS AND IDLE SWITCH ADJUSTMENT PROCEDURE)

Model:
ALL

DESCRIPTION: 
Correct adjustment of the accelerator switch, throttle position sensor (TPS) and idle switch is essential for proper driveability. An accelerator sWitch, 
TPS or idle switch out of adjustment may cause one or more of the following driveability conditions:

^

Park to Reverse or Park to Drive engagement shock

^

Engine speed fluctuation between 1000-1700 rpm during slow cruise at light throttle opening or during deceleration

^

Harsh 4-3 downshift shock when decelerating to a stop

^

Harsh 1-2 and 2-3 upshift

^

Rough idle

It a vehicle has a driveability condition, verify the adjustment of the accelerator switch (if equipped), TPS and idle switch according to the procedures in
the appropriate Shop Manual. These components may be checked using the scan tool (select "4-Speed Trans" menu). Adjust these components if
necessary. 

For your convenience, the reference pages in each Shop Manual are listed in this TSB. 

Note: 

TPS is not adjustable on the OBD-II vehicles listed below. For these vehicles, check the operation of TPS and idle switch at idle and open throttle
using the scan tool (select "4-Speed Trans", "Codes and Data" and "Data" menus).
