P0732

DTC P0732: Gear 2 Incorrect Ratio

DESCRIPTIONS OF MONITOR METHODS
In 2nd gear, if a difference between turbine revolution and that value calculated from output revolution equals or exceeds specified value, TCM judges that step-out in 2nd gear has occurred.

MONITOR EXECUTION
Continuous

LOGIC FLOW CHARTS (Monitor Sequence):

DTC SET CONDITIONS (Entry Conditions and Malfunction Thresholds)

Check Conditions
- Engine speed: 450 r/min or more.
- Output speed: 500 r/min or more.
- Shift stage: 2nd gear.
- Input speed: more than 0 r/min.
- Transmission fluid temperature sensor voltage: 4.5 volts or less.
- Voltage of battery: 10 volts or more.
- Transmission range switch rationality: only one signal.
- Time after shift changing finish: 2 seconds or more.

Judgement Criteria
- Output speed: [(input speed + 200 r/min) / 2nd gear ratio] or more. (4 seconds)
- Output speed: [(input speed - 200 r/min) / 2nd gear ratio] or less. (4 seconds)

OBD-II DRIVE CYCLE PATTERN
Start the engine, and drive at 30 km/h (19 mph) or more for 10 seconds, with 2nd gear fixed (2 range or 2nd gear in sport mode).
