Poor acceleration
Probable cause (s)
- Traction motor defective: worn or damaged:
-
- Stator
- Rotor
- Position sensor
- Position sensor line
- Terminal plate
- Transmission fluid temperature sensor
- Sensor harness
- 3-phase wires
- Traction motor defective; faulty installations:
-
- Stator
- Position sensor
- Terminals
- 3-phase wire terminals
- Traction motor stator temperature high
- Traction motor rotor temperature high
- Traction motor position sensor not learned
- Generator motor defective: worn or damaged:
-
- Stator
- Rotor
- Position sensor
- Position sensor line
- Terminal plate
- 3-phase wires
- Generator motor defective; faulty installations:
-
- Stator
- Position sensor
- Terminals
- 3-phase wire terminals
- Generator motor stator temperature high
- Generator motor position sensor not learned
- Engine output low
- Low ATF level
- ATF pump worn or binding
- Main regulator valve stuck or spring worn
- Foreign material in separator plate orifice
- Cooler relief valve defective
- ATF strainer clogged
- ATF cooler clogged
NOTE:
- Check the engine control system.
- Check the ATF level. If the level is below the lower level, check the ATF cooler lines for leaks and loose connections. If necessary, clean the ATF cooler lines.
- Inspect the motor shaft for wear and damage.
- Inspect the generator shaft for wear and damage.
- Check the ATF pump drive gears for wear and damage.
- Replace the valve body assembly .
- Check for a clogged orifice in the separator plate. If the orifice is clogged, remove it and clean the separator plate orifice.
- Check the ATF strainer for debris. If the strainer is clogged, find the damaged components that caused the debris.
- Check the ATF cooler.
- Replace the transmission (e-CVT) .
