Preconditions
The monitor will not run unless:

MIL is OFF.

ECT (Coolant Temp) is 176F (80C) or greater.

IAT (Intake Air) is 14F (±10C) or greater.*
* For 2002 MY and later vehicles: The readiness test can be completed in cold ambient conditions
(less than 14F / ±10C), if the drive pattern is repeated a second time after cycling the ignition OFF.
Drive Pattern Procedure
Connect the OBDII Scantool to DLC3 to check monitor status and preconditions.
Note the IAT (Intake Air) value during engine startup. The driving time must be adjusted
during step ªaº based upon IAT (Intake Air) value at startup.
a. Drive the vehicle at 40 ± 55 mph (64 ± 88 km/h) for the time described below:

If IAT (Intake Air) was less than 50F (10C) when the engine was started,
drive for 7 minutes.

If IAT (Intake Air) was greater than 50F (10C) when the engine was started,
drive for 3 minutes.
b. Drive the vehicle allowing speed to fluctuate between 35 ± 45 mph (56 ± 72 km/h)
for about 16 minutes.
NOTE:

Drive with smooth throttle operation.

Avoid sudden acceleration.

Avoid sudden deceleration as much as possible with the throttle fully closed.
If readiness status does not switch to ªcomplete,º ensure preconditions are met, turn the
ignition OFF, then repeat steps ªaº and ªb.º
NOTE:
The readiness status may not switch to ªcompleteº after the first drive pattern trip if a
Pending Code has been set (first trip for a two±trip DTC).

Pending Codes are available from the DTC Info Menu in Enhanced OBDII.

Pending Codes indicate a POTENTIAL problem was detected. A second trip is
needed to confirm the DTC prior to diagnosis.

Once a second trip is completed, a current DTC will be stored. Readiness

EG003-03Title:
SULFUR ODOR FROM EXHAUST
Models:
All Models
Technical Service
BULLETIN
February 24, 2003

Some owners of Toyota vehicles may experience a sulfur±like or ªrotten eggº odor from
the exhaust system. Sulfur is a natural component of crude oil from which gasoline is
refined and the amount of sulfur can be decreased through the refining process. The
amount of sulfur in fuel sold in California is regulated, however gasoline sold in other
states can have substantially higher sulfur content. Sulfur content also varies
considerably between gasoline brands and locations.
All Models.
A sulfur odor emitted from the vehicle's tailpipe does not necessarily indicate that there is
an issue with the engine's running condition, but is most likely directly related to the fuel.
If the vehicle is exhibiting an excessive sulfur odor, the following checks should be
performed:
If the MIL light is ON, check for DTCs and repair as necessary.
If no trouble is found after performing the above check, recommend the customer try a
different source of fuel.
Replacement of oxygen sensors, air/fuel ratio sensors or catalytic converters will not
reduce the odor and will therefore not
be considered warrantable.

Technical Service
BULLETIN
April 20, 2001

Under certain driving conditions, some 1997 ± 1999 5S±FE California emission
specification Camrys and 1999 5S±FE California emission specification Solaras may
exhibit a M.I.L. ªONº with DTC P1133 (Air Fuel Ratio Sensor Slow Response
Malfunction). An improved Air Fuel Ratio (A/F) Sensor was developed to correct this
condition (See TSB EG006±99).
In some rare cases, P1133 may still set after the improved A/F sensor is installed. The
Engine Control Module (ECM) logic has been modified to correct this condition.
1997 ± 1999 model year Camrys with 5S±FE California emission specification.
1999 model year Solaras with 5S±FE California emission specification.

1. Should a M.I.L. ªONº condition with P1133 be encountered, perform diagnostic
procedures as described in the Repair Manual.
2. If the problem source cannot be identified after checking all affected areas according
to the Repair Manual, the cause may be an A/F Sensor or ECM logic malfunction. In
this case, follow the procedure in the flowchart below to determine which part needs
to be replaced.
Replace the ECM only if the A/F Sensor in the vehicle was produced after
