DANGER:

Since hybrid vehicles and electric vehicles contain a high voltage battery, there is the risk of

electric shock, electric leakage, or similar accidents if the high voltage component and vehicle are

handled incorrectly. Be sure to follow the correct work procedures when performing inspection and

maintenance.

WARNING:

• Be sure to remove the service plug in order to disconnect the high voltage circuits before perform-

ing inspection or maintenance of high voltage system harnesses and parts.

• The removed service plug must always be carried in a pocket of the responsible worker or placed in

the tool box during the procedure to prevent the plug from being connected by mistake.

• Be sure to wear insulating protective equipment consisting of glove, shoes, face shield and glasses

before beginning work on the high voltage system.

• Never allow workers other than the responsible person to touch the vehicle containing high voltage

parts. To keep others from touching the high voltage parts, these parts must be covered with an insu-

lating sheet except when using them. Refer to 

GI-34, "High Voltage Precautions"

.

REFRIGERANT PRESSURE SENSOR

Never bring the vehicle into the READY status with the service plug removed unless otherwise

instructed in the Service Manual. A malfunction may occur if this is not observed.

REMOVAL

1. Remove liquid tank. Refer to 

HA-110, "LIQUID TANK : Removal and Installation"

.

2. Use a vise (A) to fasten the liquid tank (1) in place, then use a

spanner wrench (B) and remove refrigerant pressure sensor (2).

CAUTION:

• Wrap the liquid tank with shop cloth to prevent scratches.

• To prevent the inclusion of foreign matter, use a cap or

vinyl tape to seal off the refrigerant pressure sensor

mounting point on the liquid tank from the atmosphere.

INSTALLATION

Note the following items, and then install in the reverse order of removal.

CAUTION:

• To prevent leakage of refrigerant, replace the O-ring with a new one. Apply a coat of compressor oil

to the O-ring prior to installation.

• Perform a check for refrigerant leakage when charging with refrigerant. Refer to 

HA-84, "Check

Refrigerant Leakage"

.
