Description
The ecm uses signals from the vehicle speed sensor to detect the actual gear position (1st, 2nd, 3rd or o/d gear).
Then the ecm compares the actual gear with the shift schedule in the ecm memory to detect mechanical problems of the shift solenoid valves, valve body or automatic transaxle (clutch, brake, gear, etc.).
Monitor description
The ecm commands gear shifts by turning the shift solenoid valves on/off. According to the input shaft revolution, intermediate (counter) shaft revolution and output shaft revolution, the ecm detects the actual gear position (1st, 2nd, 3rd or o/d gear position). When the gear position commanded by the ecm and the actual gear position are not the same, the ecm illuminates the mil.
Example: when either condition (a) or (b) is met, the ecm detects a malfunction.
Monitor strategy
Typical enabling conditions
Typical malfunction thresholds
Either of the following conditions is met: off malfunction, or on malfunction (a) and (b) 2 detections are necessary per driving cycle: 1st detection: temporary flag on
2Nd detection: pending fault code on
Inspection procedure
Hint:
Performing the intelligent tester's active test allows relay, vsv, actuator and other items to be operated without removing any parts. Performing the active test early in troubleshooting is one way to save time.
The data list can be displayed during the active test.
Hint:
While driving, the shift position can be forcibly changed with the tester. Comparing the shift position commanded by the active test with the actual shift position enables you to confirm the problem (see page ax-31).
Hint:
Result
Hint:
If any other codes besides p0746 are output, perform the troubleshooting for those dtcs first.
Standard resistance: 5.0 To 5.6 Ùat 20°c (68°f)
Ok: valve moves and makes operating noise.
Ok: there are no foreign objects on each valve.
Ok: the torque converter clutch operates normally.
Repair or replace automatic transaxle assembly
Installation
Hint:
Use the same procedures for the rh side and lh side.
The procedures listed below are for the rh side.
Install front seat assembly
Place the seat in the cabin.

Manual shifting test
Hint:
Through this test, it can be determined whether the
trouble occurs in the electrical circuit or if it is a
mechanical problem in the transaxle.
If any abnormalities are found in the following test, the
problem is in the transaxle itself.
