Monitor Operation
The monitor sequence begins with a cold
engine start. The IAT and ECT sensors
must have approximately the same
temperature reading.
The ECM is constantly monitoring fuel
tank pressure. As the temperature of the
fuel increases, pressure slowly rises.
The ECM will purge the charcoal canister
at the appropriate time (see Figure 1).
With bypass VSV closed, pressure will
continue to rise in fuel tank.

PRELIMINARY CHECK
Fuel level should be between
1/4 and 3/4
Visually inspect for presence
of Fuel/Gas Cap
DO NOT TIGHTEN OR REMOVE!
PRESSURIZE EVAP SYSTEM (System Integrity Check)
This test checks for leaks in the canister and fuel tank sides. The CCV and Air Inlet Lines will be checked
separately.
A) Clamp the air drain hose on the charcoal canister with the supplied hose pliers from the EVAP System
Pressure Test Kit.
B) Locate the vapor pressure sensor. If the vapor pressure sensor has two hoses connected to it,
disconnect the hose between the air drain hose fitting at the vapor pressure sensor and plug the hose.
C) 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.
D) 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 ªClosed).
E) After 30 seconds, note the pump pressure gauge reading and the Scan Tool vapor pressure
sensor reading.
F) Compare the readings to one of the four conditions listed below and proceed as directed.
DO NOT PROCEED! NG
OK
SCAN TOOL SETUP
A) Connect Scan Tool to DLC3 on vehicle.
B) Go to the SETUP menu and select UNIT CONVERSION.
C) Under VAPOR PRESSURE, Select ABS for absolute pressure, and mmHg for millimeters of mercury.
This is to match the Repair Manual specifications.
D) Go back to FUNCTION SELECT menu and select ENHANCED OBD II.
E) Select NORMAL MODE. Then select CURRENT DATA and USER SELECT.
F) Using the arrow key, select VAPOR PRESS from the DATA LIST and select YES.
G) Press ENTER. You will now be able to monitor the Vapor Pressure Sensor reading.

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

Under certain driving conditions, some 5S±FE equipped 1997±1999 Camry and 1999
Solara California emission specification vehicles may exhibit a M.I.L. ªONº DTC P1133.
An improved Air Fuel Ratio Sensor has been developed to correct this condition.

Should a M.I.L. ªONº condition with DTC P1133 be encountered, perform diagnostic
procedures as described in the Repair Manual.
If the problem source cannot be identified after checking all affected areas according
to the Repair Manual, the cause may be an Air/Fuel Ratio Sensor malfunction. In this
case, replace the Air/Fuel Ratio Sensor with the updated part.
If the Exhaust Manifold threads are damaged by removal of the sensor, they can be
repaired by the proper use of a M18 x 1.5 tap.

1. Confirm if vehicle is currently misfiring, running rough or hesitating.
If YES ± Go to Step 2.
If NO ± Review Freeze Frame Data and attempt to operate vehicle under similar
driving conditions ± see notes below for information that makes it more likely to
duplicate misfire.
NOTE:
The following activities will turn off misfire detection:
Changing engine RPM greater than 150 RPM.
Changing throttle position quickly.
Misfire duplication can be duplicated most readily when the engine speed and throttle
angle are held nearly constant for at least 2 minutes.

Is the cylinder(s) identified by the DTC(s) misfiring?
If YES ± Go to Step 3.
If NO ± Follow normal diagnostics for applicable DTC in Technical Information System
(TIS) in applicable Repair Manual:
Diagnostics: SFI: P030#.
3. Swap suspect ignition coil(s) from cylinder that is misfiring to cylinder that is
not misfiring.
4. Using Diagnostic Tester, confirm that misfire is now occurring in cylinder that has
suspect ignition coil(s). Has misfire followed swapped ignition coil(s)?
If YES ± Replace ignition coil(s) and go to Step 5.
If NO ± Follow normal diagnostics in Technical Information System (TIS) for
applicable Repair Manual:
Diagnostics: SFI: P030#.
5. Confirm misfire has been eliminated (0% at all times) using Diagnostic Tester while
engine is idling.
NOTE:
If misfire percent is any value other than 0% at any time, then that cylinder is misfiring. Repair
