P0735

DTC P0735 GEAR 5 INCORRECT RATIO

COMPONENT LOCATION:

GENERAL DESCRIPTION
The value of the input shaft speed should be equal to the value of the output shaft speed, when multiplied by the 5th gear ratio, while the transaxle is engaged in the 5th gear. For example, if the output speed is 1,000 rpm and the 5th gear ratio is 0.868, then the input speed is 868 rpm.

DTC DESCRIPTION
This code is set if the value of input shaft speed is not equal to the value of the output shaft, when multiplied by the 5th gear ratio, while the transaxle is engaged in 5th gear. This malfunction is mainly caused by mechanical troubles such as control valve sticking or solenoid valve malfunctioning rather than an electrical issue.

DTC DETECTING CONDITION:

SIGNAL WAVEFORM:

MONITOR SCANTOOL DATA
- Go to "Signal circuit Inspection" procedure

OPERATING ELEMENT OF EACH SHIFTING RANGE:

Low & Reverse Brake is released When the vehicle speed over the 5MPH (7km/h)

SIGNAL CIRCUIT INSPECTION
1. Connect Scan tool.
2. Engine "ON".
3. Monitor the "INPUT & OUTPUT SPEED SENSOR" parameter on the scan tool.
4. Accelerate the Engine speed until about 2000 rpm in. the 5th gear.
Specification: INPUT SPEED - (OUTPUT SPEED x GEAR RATIO) less than or equal to 200 RPM





5. Does "INPUT & OUTPUT SPEED SENSOR" follow the reference data?
YES
- Go to "Component Inspection" procedure.

NO
- Check for electrical noise of circuit in INPUT & OUTPUT SPEED SENSOR or Replace INPUT & OUTPUT SPEED SENSOR. Repair as necessary and Go to "Verification of Vehicle Repair" procedure.

COMPONENT INSPECTION





1. Connect oil pressure gauge to "OD" and "2nd" and "DIR" port.
2. Engine "ON".
3. Drive a car with gear position "5".
4. Compare it with reference data as below.
Specification: refer to Standard Oil Pressure Table (DTC P0731)
5. Is oil pressure value within specification?
YES
- Repair AUTO TRANSAXLE (Clutch or Brake) as necessary and Go to "Verification of Vehicle Repair" procedure.

NO
- Replace AUTO TRANSAXLE (BODY CONTROL VALVE faulty) as necessary and Go to "Verification of Vehicle Repair" procedure.

VERIFICATION OF VEHICLE REPAIR
Refer to DTC P0731. P0731
