TROUBLESHOOTING <A/T>

AUTOMATIC TRANSMISSION (FF)

23A-86

Code No.41 (1st),  42 (2nd), 43 (3rd), 44 (4th), 46 (reverse): Gear incorrect ratio

OPERATION
The engine-A/T-ECU detects the current gear/speed 
according to the output signals from the input and 
output shaft speed sensor.

diagnosis code set conditions
If the output from the output shaft speed sensor 
multiplied by the gear ratio is not the same as the 
output from the input shaft speed sensor after 
completing of shifting, the corresponding diagnosis 
code is output.
If each diagnosis code is output 4 times, the 
transmission is fixed in 3rd as a fail-safe measure.

Possible causes

Malfunction of input shaft speed sensor

Malfunction of output shaft speed sensor

Damaged harness wires and connectors

Malfunction of the engine-A/T-ECU

Malfunction of solenoid valve

Malfunction of underdrive clutch retainer

Malfunction of valve body

Malfunction of transfer drive gear or driven gear

Malfunction of low-reverse brake system (for 
diagnosis codes 41, 46)

Malfunction of underdrive clutch system (for 
diagnosis codes 41, 42, 43)

Malfunction of second brake system (for 
diagnosis codes 42, 44)

Malfunction of overdrive clutch system (for 
diagnosis codes 43, 44)

Malfunction of reverse clutch system (for 
diagnosis code 46)

Malfunction of one-way clutch system (for 
diagnosis code 41)

DIAGNOSIS

STEP 1. MUT-II/III diagnosis code

Either of diagnosis codes 41, 42, 43, 44 or 46 is 
output, the input shaft speed sensor or output shaft 
speed sensor is defective.

Q: Are diagnosis codes 22 or 23 output?

YES <diagnosis code 22 is output> : 

Refer to 

diagnosis code 22 input shaft speed sensor 
system

.

YES <diagnosis code 23 is output> : 

Refer to 

diagnosis code 23 output shaft speed 
sensor system 

P.23A-37

.

NO : 

Go to Step 2.

STEP 2. MUT-II/III diagnosis code

Either of diagnosis codes 41, 42, 43, 44 or 46 is 
output, the corresponding solenoid valve is defective.

Q: Is either of diagnosis code 31, 32, 33, 34 output?

YES <diagnosis code 31 is output> : 

Refer to 

diagnosis code 31: Low-reverse solenoid 
valve system 

P.23A-65

.

YES <diagnosis code 32 is output> : 

Refer to 

diagnosis code 32: Underdrive solenoid 
valve system 

P.23A-70

.

YES <diagnosis code 33 is output> : 

Refer to 

diagnosis code 33: Second solenoid valve 
system 

P.23A-74

.

YES <diagnosis code 34 is output> : 

Refer to 

diagnosis code 34: Overdrive solenoid valve 
system 

P.23A-78

.
