1. Remove all six fuel injectors for
verification of production information.
Affected injectors will be labeled with
a vendor part number of
ª23250±0A010ª and have a
production date code number of ª828ª
or lower (see illustration for number
locations).
2. After determining that one or more of
the injectors are affected, replace all
six injectors with the above applicable
part number.
3. Clear the DTC, if present, and verify
that the vehicle now operates as
designed.

TSB Revision Notice:
The information updated in this TSB is red
and underlined.
Under certain driving conditions, some 1MZ±FE equipped 1997 ± 1999 Camry California
Emission specification vehicles can 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 current part number listed above.
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.

Applicable Warranty*:
This repair is covered under the Toyota Basic Warranty. This warranty is in effect for
36 months or 36,000 miles, whichever occurs first, from the vehicle's in±service date.
Coverage is extended to 36 months or 50,000 miles, whichever occurs first, in the
states of California and Massachusetts due to state emissions warranty legislation.
NOTE:
Please enter the DTC in the condition/Cause/Remedy section when applying for
warranty reimbursement.
* Warranty application is limited to correction of a problem based upon a customer's specific complaint.

During vehicle processing by Dealers, care must be taken to avoid applying undercoating in the
area surrounding the Oxygen Sensors. Application of undercoating on or near the Oxygen Sensors
can cause insufficient air to flow around the sensor, and inaccurate information storage by the ECM.
If this condition occurs, the Malfunction Indicator Light (MIL) may illuminate.

TSB REVISION NOTICE:
The information updated in this TSB is red
and underlined.
The On±Board Diagnostic (OBDII) system is designed to monitor the performance of
emission±related components and report any detected abnormalities in the form of
Diagnostic Trouble Codes (DTCs). Since the various components need to be monitored
during different driving conditions, the OBDII system is designed to run separate
monitoring programs called Readiness Monitors. Many state Inspection and
Maintenance (I/M) programs require that vehicles complete their Readiness Monitors
prior to beginning an emissions test.
The current status of the Readiness Monitors can be seen by using the Toyota Diagnostic
Tester with version 9.0 software (or newer), or a generic OBDII Scantool.
To view the Readiness Monitor status using the Toyota Diagnostic Tester, select ªMonitor
Statusº from the Enhanced OBDII Menu.
A status of ªcompleteº indicates that the necessary conditions have been met to run the
performance tests for the related Readiness Monitor.
The Readiness Monitor will be reset to ªincompleteº if:
ECU has lost power (battery or fuse).
DTCs have been cleared.
The conditions for running the Readiness Monitor have not been met.
In the event that any Readiness Monitor shows ªincomplete,º follow the appropriate
Readiness Monitor Drive Pattern to change the readiness status to ªcomplete.º
Refer to the Readiness Monitor Drive Pattern Application Table to determine which
drive pattern should be followed.

NOTE:
A generic OBDII Scantool can be used in place of the Toyota Diagnostic Tester.
CAUTION:
Strict observance of posted speed limits, traffic laws and road conditions are
required when performing these drive patterns.
NOTE:
These drive patterns represent the fastest method to satisfy all necessary
conditions which allow the specific Readiness Monitor to complete.
In the event that the drive pattern must be interrupted (possibly due to traffic
conditions or other factors) the drive pattern can be resumed and, in most cases,
the Readiness Monitor will still set to ªcomplete.º
To ensure rapid completion of Readiness Monitors, avoid sudden changes in
vehicle load and speed (driving up and down hills and/or sudden acceleration).
