33. Check the APP SENSOR in the Data List with theHDS. Do not press the accelerator.
Check the APP sensor (see page 11-268).
Reconnect all connectors, then update the
PCM if it does not have the latest software
(see page 11-227), or substitute a known- good PCM
(see page 11-7), then recheck. If the symptom goes
away with a known-good PCM, replace the original
PCM (see page 11-228). SRS components are located in this area. Review the
SRS component locations (see page 24-11) and the
precautions and procedures (see page 24-13) before
doing repair or service.
1. Turn the ignition switch to ACCESSORY (I). The shift lever must be in P.
2. Disconnect the steering lock assembly connector.
3. Check if the ignition switch can be turned to the LOCK (0) position.
Go to step 4.
Replace the ignition key cylinder/steering lock
assembly (see page 17-14).
4. Turn the ignition switch to LOCK (0).
5. Move the shift lever out of P.
6. Check for continuity between steering lock assembly connector terminal No. 3 and body
ground.
Repair short to body ground in the wire
between the key interlock solenoid and the
MICU.
Go to step 7.
7. Remove the shift lever assembly (see page 14-254).

14. Install the three dowel pins (A) and a new gasket (B)on the torque converter housing (C).
15. Align the spring pin (D) of the selector control shaft (E) with the transmission housing groove (F) by
turning the control shaft. Do not squeeze the end of
the control shaft tips together when turning the
shaft. If the tips are squeezed together, it will cause
a faulty shift position signal or position due to the
play between the control shaft and the
transmission range switch.
16. Place the transmission housing (G) on the torque converter housing. Do not install the input shaft
(mainshaft) speed sensor and the output shaft
(countershaft) speed sensor before insta lling the
transmission housing on the torque converter
housing. 17. Use snap ring pliers to expand the snap ring of the
secondary shaft bearing. Then push the
transmission housing down to start the secondary
shaft bearing through the snap ring. Then release
the pliers. While rotating the reverse idler gear with
a screwdriver, push down the housing until it
bottoms and snap ring snaps in place in the
secondary shaft bearing snap ring groove.
18. Check that the secondary shaft bearing snap ring (A) is seated in the bearing and the housing groove,
and that the ring end gap (B) is correct.
19. Install the transmission housing mounting bolts along with the transmission hanger and the
harness clamp brackets, and tighten the 19 bolts in
at least two steps in a crisscross pattern.
