Checking the main pressure (Mazda CX-5KE)

1. Perform mechanical check as described above.

2. Remove the air filter.

3. Remove the wiring bracket.





4. Unscrew the square plug of the pressure test port.

Original version of the article on the website [MAZBOOK]

Caution: Do not remove the square plug when the automatic transmission fluid temperature is high. Otherwise, the automatic transmission fluid may splash out and cause serious burns. Remove the square plug of the pressure test port only after the transmission has cooled down sufficiently.

Note: Use a suitable oil pressure gauge with the appropriate measuring range.

Note: replace the part with a new one after each removal.

5. Install special equipment (49 0019 908, 49 0019 909, 49 0019 910, 49 0019 911, 49 0019 913) to the pressure test port as shown in the figure.





6. Install the engine air filter.

7. Start the engine.

8. Warm up the gearbox to a working fluid temperature of 60-70°C.

9. Move the selector lever to position D.

10. Measure the main pressure at idle speed in position D.

11. Similarly, measure the main pressure at idle speed in positions M (first gear) and R.

12. Stop the engine.

13. Replace the low pressure gauge (49 0019 908) on the high pressure gauge (49 0019 907).

14. Start the engine.

15. Measure the line pressure in stop mode in position D of the transmission:

• Press the brake pedal firmly with your left foot.
• Move the selector lever to position D.

Caution: To prevent damage to the gearbox, measure the line pressure in stop mode for no longer than five seconds.

• With your right foot, slowly press the accelerator pedal all the way down.
• Quickly read the value of the main pressure in stop mode and remove your right foot from the accelerator pedal.
• Move the selector lever to position N and reduce the engine speed to idle for one minute or more.

16. Similarly, measure the main pressure in the stop mode for all other positions except D.

17. If any malfunctions are detected, search for the cause and troubleshoot.

Note: Line pressure values are given in the table at the beginning of this chapter.

18. Stop the engine.

19. Remove the air filter.

20. Remove special equipment.

Caution: If the special equipment is removed when the automatic transmission fluid temperature is high, the automatic transmission fluid may splash out and cause serious burns. Remove the special equipment only after the transmission has cooled down sufficiently.

21. Install a new square plug onto the pressure test port and tighten to 7.2-9.8 Nm.

Note: Do not reuse the square plug as it has a sealing coating that is damaged during installation.

22. Install the wiring bracket and tighten the mounting bolts to a torque of 10 Nm.

23. Install the engine air filter.
