CCV and Air Inlet Line Check. (Except ECHO)
A) Disconnect the air inlet line from the charcoal canister.
B) Using the supplied step±down brass adapter (or equivalent) connect the Pressure Supply Hose to
the air inlet line.
C) Using the Scan Tool Active Test, turn on the CCV. This will close the CCV.
D) Pressurize the line. Once pressurized, turn off the pump and seal the line (Pressure Hold Switch to
ªClosedº and Vent Switch to ªClosedº). Pressure should hold. If not, check CCV and connections.
E) Next, using the Scan Tool, turn off the CCV. This will open the CCV. The pressure should decrease.
If not, check the CCV and connections.
F) After completing the test, reconnect air inlet line to charcoal canister. Diagnostic Process Flow Chart (Continued)

Disconnect
EVAP Hose Here
A. Using the supplied brass step±down adapter, disconnect the EVAP hose from
the charcoal canister side as indicated above. Connect Pressure Supply hose
from Pressure Test Kit to the EVAP hose and pressurize the fuel tank to
30 mmHg (4 kPa / 0.58 psi).
B. Check that the internal pressure of the tank will hold for 1 minute. Check shaded
areas for leaks (soapy water can be used for leak detection). If pressure holds, then
perform the Canister Leak Check.
C. When done, reconnect the EVAP line hose to the charcoal canister. Fuel Tank Leak Check (Except ECHO)
Canister Leak Check (Except ECHO)
A. Connect the Pressure Supply hose from the Pressure Test Kit to the Green EVAP
System Service Port located on the EVAP Purge VSV line in the engine compartment.
B. Using the directions on the inside of the EVAP System Pressure Test Kit lid,
pressurize the EVAP system. Once pressurized, turn off the pump and seal the system
(Pressure Hold Switch to ªClosedº and Vent Switch to ªClosedº)
C. With system pressurized at EVAP Service Port, check shaded areas for leaks (soapy
water can be used for leak detection). Diagnostic

Technical Service
BULLETIN
March 22, 2002
To help prevent unnecessary complications during the oil fill process, no undue load
should be placed on the oil baffle attached to the inside of the valve cover (see
illustration). This baffle is designed to deflect oil and should not be used to support
the weight of heavy oil fill devices. These devices can place stress on the baffle, and
bend or break it during the oil fill process.
All 1993 ± 2003 model year Toyota vehicles.
Please take measures to ensure that the baffle is not damaged during the oil fill process.
If it does become damaged, repair it before any collateral damage occurs.

Under certain driving conditions, some 1998 ± 1999 model year Camry and Solara
vehicles may exhibit a M.I.L. ªONº with DTCs P0440, P0441 and P0446 stored due to an
inoperative Vapor Pressure Sensor 3 way Vacuum Switching Valve (VSV). An improved
Vapor Pressure Sensor VSV has been developed to correct this condition.
1998 ± 1999 model year Camry & Solara vehicles.
