STEP 8. Check the harness between A/T control
solenoid valve assembly connector B-34 terminal
No.1 and engine-A/T-ECU connector C-142
terminal No.119.
Check the output line for short-circuited or open
circuit.
Q: Is the check result normal?
YES :
Go to Step 5.
NO :
Repair the wiring harness.

TROUBLESHOOTING <A/T>
AUTOMATIC TRANSMISSION (FF)

OPERATION
The input shaft speed sensor detects the speed of
the underdrive clutch retainer, and sends the
information to the engine-A/T-ECU as a pulse signal.
diagnosis code set conditions
The diagnosis code No. 22 will be set if the input
shaft speed sensor does not send a pulse signal for
one second or more while the 3rd gears are engaged
and the vehicle speed is 40 km/h or more (the output
shaft speed sensor speed is 1000 r/min or more).
If the code No. 22 is set four times, the transmission
will be fixed in 3rd gear as a fail-safe measure.
However, the transmission can be downshifted to
2nd gear by operating the selector lever.
Possible causes
•
Malfunction of input shaft speed sensor
•
Malfunction of underdrive clutch retainer
•
Damaged harness wires and connectors
•
Malfunction of the engine-A/T-ECU
DIAGNOSIS
STEP 1. MUT-II/III data list
Item 22: Input shaft speed sensor (Refer to data list
reference table
Q: Is the check result normal?
YES :
Intermittent malfunction (Refer to GROUP

−
How to Cope with Intermittent
Malfunction
NO :
Go to Step 2.
STEP 2. Connector check: B-36 input shaft speed
sensor connector
Check for the contact with terminals.
Q: Is the check result normal?
YES :
Go to Step 3.
NO :
Repair the defective connector.
STEP 3. Measure the resistance at input shaft
speed sensor connector B-36.
Disconnect the connector, and measure the
resistance between terminal 1 and earth at the wiring
harness side.
OK: 2
Ω
or less
Q: Is the check result normal?
YES :
Go to Step 9.
NO :
Go to Step 4.
STEP 4. Measure the voltage at engine-A/T-ECU
connector C-141.
(1) Connect input shaft speed sensor connector
B-36.
(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between engine-A/T-ECU
connector C-141 terminal No.88 and earth.
OK: 0.5 V or less
