Removal and InstallationEBS00KP5
REMOVAL
1. Disconnect accelerator pedal position sensor harness connector.
2. Loosen nuts, and remove accelerator pedal assembly.
CAUTION:

Do not disassemble accelerator pedal assembly. Do not remove accelerator pedal position sen-
sor from accelerator pedal assembly.

Avoid impact from dropping etc. during handling.

Be careful to keep accelerator pedal assembly away from water.

Do not adjust adjusting screw (painted white).
INSTALLATION
Installation is the reverse order of removal.
INSPECTION AFTER INSTALLATION

Make sure that accelerator pedal moves smoothly within the whole operation range.

Make sure that accelerator pedal securely returns to the original position.

For the electrical inspection of accelerator pedal position sensor, refer to EC-409, "DTC P2122, P2123
APP SENSOR" (QR20DE and QR25DE) or EC-1099, "DTC P0122, P0123 APP SENSOR" (YD22DDTi).
CAUTION:
When the harness connector of the accelerator pedal position sensor is disconnected, perform
“Accelerator Pedal Released Position Learning”. (QR20DE and QR25DE) Refer to EC-46, "
Acceler-
ator Pedal Released Position Learning" (WITH EURO-OBD) or EC-559, "Accelerator Pedal
Released Position Learning" (WITHOUT EURO-OBD).
NOTE:
In the case of YD22DDTi, it is unnecessary to perform “Accelerator Pedal Released Position Learning”
even when disconnecting the harness connector of the accelerator pedal position sensor.

STALL TEST PROCEDURE
1. Check A/T fluid and engine oil levels. If necessary, add.
2. Drive vehicle for approx. 10 minutes or until fluid and oil reach
operating temperature. Refer to AT- 1 6 , "
Checking A/T Fluid" .
3. Set parking brake and block wheels.
4. Install a tachometer where it can be seen by driver during test.

It is good practice to mark the point of specified engine
rpm on indicator.
5. Start engine, apply foot brake, and place selector lever in D
position.
6. Accelerate to wide open throttle gradually while applying foot
brake.
7. Quickly note the engine stall revolution and immediately release
throttle.

During test, never hold throttle wide open for more than 5
seconds.

INSPECTION
Installation and inspection of torque converter

After inserting a torque converter to a transaxle, be sure to
check distance “A” to ensure it is within the reference value limit.
InstallationECS004ND
Install the removed parts in the reverse order of the removal, while paying attention to the following work.

When installing transaxle to the engine, attach the fixing bolts in
accordance with the following standard.

Align the positions of tightening bolts for drive plate with those of
the torque converter, and temporarily tighten the bolts. Then,
tighten the bolts to the specified torque. Refer to AT- 4 1 6 , "
Com-
ponents" .
CAUTION:

When turning crankshaft, turn it clockwise as viewed from
the front of the engine.

When tightening the tightening bolts for the torque con-
verter after fixing the crankshaft pulley bolts, be sure to
confirm the tightening torque of the crankshaft pulley
mounting bolts.

After converter is installed to drive plate, rotate crankshaft
several turns and check to be sure that transaxle rotates freely without binding.

After completing installation, check for fluid leakage, fluid level, and the positions of A/T. Refer to AT- 1 6 ,
"Checking A/T Fluid" , AT- 4 0 9 , "CONTROL CABLE ADJUSTMENT" .
