Inspection
If you have trouble code related to the pressure sensor (P1825, P1826, P1827, P1828), check pressure sensor according to the inspection process.
Pressure Sensor Inspection Procedure

Measure the resistance of pressure sensor
1.
Turn ignition switch OFF.
2.
Disconnect the pressure sensor connector.
3.
Measure resistance between sensor terminal and terminal.
4.
Check the measured resistance. (Refer to table)
Terminal
Resistance
PIN 2 – PIN 3
2.755 ~ 4.133 kΩ
PIN 1 – PIN 3
1.892 ~ 2.838 kΩ
PIN 1 – PIN 2
1.714 ~ 2.838 kΩ

Removal
1.
Remove the coupling assembly.
(Refer to "coupling assembly" in 4WD group)
2.
Remove the extension Cable (A).

3.
Remove the pressure sensor (A) with 24mm socket.
Keep going horizontal state to prevent leaks during remove the pressure sensor.

Tightening torque:
7.8 ~ 9.8 N.m (0.8 ~ 1.0kgf.m, 5.8 ~ 7.2 lb-ft)

Installation
Check the cleanliness of the pressure sensor before installation.
Check the pressure sensor O-ring (A).

1.
Installation is the reverse of removal.
