BULLETIN
December 17, 2003
This Service Bulletin contains Oxygen Sensor (O2S) Monitor threshold values for all
models from 1996 to 2003 and some 2004 models. Starting in 2004, the O2S Monitor
threshold values can be found in the repair manual. These values are used when
analyzing the O2S test results to determine the O2S condition.
All 1996 ± 2003 model year Toyota vehicles.
2004 model year Corolla, ECHO, Matrix and Sienna vehicles.
2004 model year Scion xA and xB vehicles.
Checking O2S Test Results
To view O2S test results, the O2S Monitor must be completed and the test results must
be checked within the same key cycle. If the ignition key is cycled OFF, the O2S test
results will be set to the minimum or maximum limits, and all test results will be erased.
The O2S test results are stored in the ECU (SAE term: Powertrain Control Module/PCM)
when the monitor is completed. The test results are static and will not change once the
monitor is complete.
The process for checking O2S test results is described in the following three basic steps:
1. Completing the O2S Readiness Monitor (page 2).
2. Accessing O2S Test Results (page 3).
3. Comparing O2S Test Results to Failure Thresholds (page 4).

HINT:
The O2S Monitor is completed when the following conditions are met:
Two (2) minutes or more passed after the engine start.
The Engine Coolant Temperature (ECT) is 167F (75C) or more.
Cumulative running time at 30 mph (48 km/h) or more exceeds 6 minutes.
Vehicle is in closed loop.
The fuel±cut is operated for 8 seconds or more (for Rear O2S Monitor).
A. Allow the engine to idle for two minutes.
B. Warm up the engine until the Engine Coolant Temperature (ECT) reaches 167F
(75C).
C. Drive the vehicle over 30 mph (48 km/h) for more than 40 seconds.
D. Stop the vehicle and allow the engine to idle for more than 20 seconds.
E. Repeat steps C and D at least 8 times in one driving cycle.
(Do not cycle the ignition key.)
In addition, perform the following steps for the Rear O2S Readiness Monitor:
A. Select second gear.
B. Allow the vehicle to run at 30 mph (48 km/h) or more.
C. Keep the accelerator pedal ªoff±idleº for more than 10 seconds.
D. Immediately after step C, release the accelerator pedal for at least 10 seconds
without depressing the brake pedal (to execute the fuel±cut).
E. Decelerate the vehicle until the vehicle speed reaches less than 6 mph (10 km/h).
F. Repeat steps B ± E at least twice in one driving cycle.
