INTAKE SENSOR

Removal and Installation

REMOVAL




1. Set the temperature at 18 °C (60 °F), and then disconnect the battery negative cable.
2. Use a refrigerant collecting equipment (for HFC-134a) to discharge refrigerant.
3. Remove cowl top cover. Refer to "COWL TOP".
4. Remove high-pressure pipe 2 mounting clip.
5. Remove low-pressure flexible hose bracket mounting bolts.
6. Disconnect evaporator-side one-touch joints.
a. Set a disconnector (High-pressure side: 92530-89908, Low-pressure side: 92530-89916) on A/C piping.
b. Slide a disconnector toward vehicle front until it clicks.
c. Slide A/C piping toward vehicle front and disconnect it.

CAUTION: Seal connection opening of piping with a cap or vinyl tape to avoid exposure to atmosphere.


7. Remove blower unit. Refer to "BLOWER UNIT".

INSTALLATION
Installation is basically the reverse order of removal.

CAUTION:
- Replace O-rings for A/C piping with new ones. Before installing, apply compressor oil to them.
- Connection point for female-side piping is thin. So, when inserting male-side piping, take care not to deform female-side piping. Slowly insert in axial direction.
- Insert one-touch joint connection point securely until it clicks.
- After piping has been connected, pull male-side piping by hand to make sure piping does not come off.
