Vehicle check
Engine 2L-T, 3L, 2L:
1. Check the refrigerant pressure.
A) Connect a gauge block to the compressor service valves.
b) The reading must be greater than 206 kPa at an ambient temperature above 0°C.
When the pressure is less than 206 kPa, charge the system with refrigerant.
2. Check the pressure switch.
A) Remove the glove box.
b) Disconnect the wire connector.
V) Check continuity between switch terminals. The device should show 0 ohms. If there is no continuity, replace the switch.
3. Install the removed parts in reverse order.
Engine 1KZ-T:
1. Install the gauge block.
2. Turn away two screws and remove a door of a glove box.
3. Disconnect the pressure sensor connector.
4. Set the speed to about 2000 rpm.
5. Check sensor operation. Check the continuity between the terminals as the pressure changes, as shown in the figure.
6. Stop the engine and disconnect the block of manometers.
7. Connect the switch connector.
