NOTICE:

After the power switch is turned off, the radio receiver assembly records various types of memory and settings. As a result, after turning the power switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal. (for Audio and Visual System)

3. REMOVE FUEL TANK PRESSURE SENSOR (VAPOR PRESSURE SENSOR)

(a) Remove the tube joint clip and pull off the fuel tank pressure sensor (vapor pressure sensor) from the fuel tank assembly.

NOTICE:

Remove any dirt or foreign matter on the fuel tank pressure sensor (vapor pressure sensor) before performing this work.
Do not allow any scratches or foreign matter to get on the parts when disconnecting them as the fuel tank pressure sensor (vapor pressure sensor) has an O-ring that seals the fuel suction plate sub-assembly.
Perform this work by hand. Do not use any tools.
If the fuel suction plate sub-assembly and fuel tank pressure sensor (vapor pressure sensor) are stuck, carefully wiggle or push and pull the fuel tank pressure sensor (vapor pressure sensor) to release it. Pull the fuel tank pressure sensor (vapor pressure sensor) off the fuel suction plate sub-assembly carefully.
