Low maximum speed and poor acceleration

DESCRIPTION

Vehicle acceleration is poor at start.
Delayed acceleration when accelerator pedal is depressed while driving.

POSSIBLE CAUSE

If the clutch is stuck or does not stay in 3GR, the malfunction is in the engine circuit.
1. Clutch slippage, burnt
  - Line pressure low
  - Shift solenoid A malfunction
  - Shift solenoid B malfunction
  - Shift solenoid C malfunction
  - Shift solenoid D malfunction
  - Shift solenoid F malfunction
  - Pressure control solenoid A malfunction
  - Body GND malfunction
  - Control valve body malfunction
2. Signal malfunction
  - VSS malfunction
  - Sensor GND malfunction
  - APP sensor malfunction
  - Input/turbine speed sensor malfunction
  - MAF sensor malfunction
  - CKP sensor malfunction
3. Transaxle fixed in 3GR (Operation of fail-safe function)
  - Short or open circuit in wiring harness
  - Poor connection of connector
  - Malfunction of electronic parts of output and input system
4. Transaxle fixed in 4GR (Operation of fail-safe function)
  - Forward clutch slippage
  - VSS malfunction
  - Shift solenoid A malfunction (Stuck on)
  - Poor connection of connector
5. Insufficient starting torque (Suspected when in-gear condition, shift control and engine circuit are normal)
  - Torque converter malfunction (Poor operation, stuck)
6. Engagement of TCC operation position (Operation of fail-safe function)
  - TFT sensor malfunction (Short or open circuit)
7. Transaxle fixed in M position
  - M position switch (built-in selector lever component) malfunction
8. TR switch adjustment incorrect

NOTE:

Before following the troubleshooting steps, make sure that the Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION -- AUTOMATIC TRANSAXLE .) (See BASIC INSPECTION .)
