Hydraulic Pressure Tests
WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Do not let anyone stand in front of or behind the vehicle while this test is performed.
CAUTION:
The transmission fluid temperature should be between 70 - 90°C (158 - 194°F) during the test.
- Check the transmission fluid level and temperature. Check engine coolant temperature.
- Transmission fluid level: "H" mark on the dipstick
- Transmission fluid temperature: 70 - 90°C (158 - 194°F)
- Engine coolant temperature: 80 - 100°C (176 - 212°F)
- Raise the vehicle so that the wheels are free to turn.
- Connect the special tools (3.0 MPa (427 psi) oil pressure gauge [MD998330] and adapters [MB992127]) to each pressure discharge port.
- Apply the parking brakes fully.
- Restart the engine.
- Check that there are no leaks around the special tool port adapters.
- At the "D" position, measure the hydraulic pressure during idling (engine speed: 650 ± 50 r/min).
Standard value: 0.385 - 0.525 MPa (56 - 76 psi)
CAUTION: The throttle should not be fully open for more than five seconds. - At the "D" position, fully depress the foot brake pedal. Then fully depress the accelerator pedal while checking the hydraulic pressure indicator, and quickly read the maximum hydraulic pressure.
Standard value: Approx. 1.53 MPa (222 psi)
- Stop the engine.
- Remove the O-ring from the port plug and replace it.
- Remove the special tool, and install the plugs to the hydraulic pressure ports.
- Start the engine and check that there are no leaks around the plugs.
