No. 6 Low Maximum Speed And Poor Acceleration [Aw6A-El]: Notes

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

DESCRIPTION AND POSSIBLE CAUSE

6	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 4GR, malfunction is in engine circuit. Clutch slippage, burnt (C1 clutch, C2 clutch, C3 clutch, B1 brake) Line pressure low Incorrect accelerator opening signal VSS malfunction Input/turbine speed sensor malfunction Sensor ground malfunction Shift solenoid C malfunction Shift solenoid D malfunction Shift solenoid E malfunction Line pressure control solenoid malfunction Shift solenoid F malfunction Body ground malfunction Control valve body malfunction Transaxle fixed in 3GR or 5GR* (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 Insufficient starting torque (Suspected when in-gear, shift control and engine circuit are normal) Torque converter malfunction (Poor operation, stuck) NOTE: Before following the troubleshooting steps, make sure that the Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted. (See BASIC INSPECTION [AW6A-EL] .)

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 4GR, malfunction is in engine circuit.
- Clutch slippage, burnt (C1 clutch, C2 clutch, C3 clutch, B1 brake)
  - Line pressure low
  - Incorrect accelerator opening signal
  - VSS malfunction
  - Input/turbine speed sensor malfunction
  - Sensor ground malfunction
  - Shift solenoid C malfunction
  - Shift solenoid D malfunction
  - Shift solenoid E malfunction
  - Line pressure control solenoid malfunction
  - Shift solenoid F malfunction
  - Body ground malfunction
  - Control valve body malfunction
- Transaxle fixed in 3GR or 5GR* (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
- Insufficient starting torque (Suspected when in-gear, shift control and engine circuit are normal)
  - Torque converter malfunction (Poor operation, stuck)
    NOTE:
    Before following the troubleshooting steps, make sure that the Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted. (See BASIC INSPECTION [AW6A-EL] .)
