Description
Park Mechanism
The park mechanism locks the transmission by engaging the park pawl with the park gear which is integral with the sec-ondary drive gear' The secondary drive gear engages with the secondary driven gear which engages wit-h the final drivengear.
shifting to E position causes the park cone (installed at the end of the park rod) to press the park pawl onto the park gear.Even if the end of the park pawl rides on the top of the park gear teeth, slight movement of the vehicle will cause the parkpawl and the park gear to mesh with each other completely because the park cone receives the tension from the park rodspring The park pawl receives the tension (which acts to separate the park pawl from the park gear) from the park pawlspring.

Troubleshooting Procedures
l. How To Begin Troubleshooting
When the E indicator light has been reported on, use the appropriate procedure below to diagnose and repatr theproDlem.
A. When the @ indicator light has come on:
l connect the Honda PGM Tester or an oBD ll Scan Tool to the 16P Data Link Connector (DLc) located near the leftkick panel.
Turn the ignition switch ON (ll).
Check the DTC and note it. Also check and notethe freeze frame data.
Refer to the Diagnostic Trouble Code Chart andbegin troubleshooting.
INOICATORLIGHT
NOTE: SeetheOBDll Scan Tool or Honda PGM Tester user's manuals for specific operating instructions.
Some PGM-FI problems will also make the E indicator light come on. After repairing the pGM-Fl system, disconnect theBACK UP fuse (7.5 Al in the under-hood fuse/relay box for more than l0 seconds to reset the TCM or PCM memory, rnenrecheck.
NOTE: Disconnecting the BACK UP fuse also cancels the radio preset stations and the clock setting. Make note of theradio presets before removing the fuse so you can reset them,

Replacement
CAUTION: While replacing the speed sensor, be sure not to allow dust and other foreign parliclos to enter into the trans-mission.
'1. Disconnect the connectors for the drive pulley, the driven pulley, and the secondary gear shaft speed sensor.
2. Remove the 6 mm bolt from the transmission housing, and remove the drive pulley. the driven pulley, and the sec-ondary gear shaft speed sensors.
3. Replace the O-rings before reinstalling the drive pulley, the driven pulley, and the secondary gear shaft sp€ed sen-sors.
