Drive Pattern Preconditions
The monitor will not run unless:

MIL is OFF.

Altitude is 7800 feet (2400 m) or less.

ECT (Coolant Temp) is between 40F and 95F (4.4C ± 35C).

IAT (Intake Air) is between 40F and 95F (4.4C ± 35C).*

Cold Soak Procedure has been completed.
NOTE:
Before starting the engine, the difference between ECT (Coolant Temp) and IAT (Intake
Air) must be less than 13F (7C). (Refer to Examples 1 and 2 on previous page.)
Drive Pattern Procedure

Connect the OBDII Scantool to DLC3 to check monitor status and preconditions.

Release the pressure in the fuel tank by removing and then reinstalling the fuel tank
cap.

Start the engine and as soon as safely possible begin driving as directed.
2a. Drive the vehicle at 50 ± 65 mph (80 ± 104 km/h) for about 15 minutes. (See
illustration on previous page.)
NOTE:

Do not turn the ignition off until the drive pattern is complete.

Drive on smooth roads to reduce excessive fuel sloshing.
If vehicle speed drops under 45 mph (72 km/h) repeat step ª2a.º

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.

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.
