REVISION NOTICE
August 8, 2013 Rev1:
• Title has been updated to include DTC P0606.
Any previous printed versions of this bulletin should be discarded.
Introduction
Some vehicles may exhibit a MIL “ON” Diagnostic Trouble Code (DTC) P0138 and/or P0158 (Oxygen
Sensor Circuit High Voltage Bank 1 or 2). In some instances a P2195 or P2197 (A/F Sensor
Signal Stuck Lean) DTC may also be present. This condition may be caused by incorrect Air Fuel
Ratio Sensor response. Additionally, a P0606 (ECM/PCM Processor) DTC may be present due to

incorrect Oxygen Sensor operation. The following repair procedures should be used to properly
diagnose and repair this condition.
NOTE
• Refer to Service Bulletin No. T-SB-0398-09, “Engine Bank 1 and Bank 2 A/F and O2
Identification” before proceeding to confirm diagnosis is performed on the correct engine bank.
• Before proceeding, check for any other applicable Service Bulletin(s). Do not apply this
diagnostic procedure if there is an existing Service Bulletin for A/F or O2 sensor DTC(s).

MIL "ON" DTC P0138, P0158 and/or P0606 Diagnostic Tips
Diagnostic Procedure (Continued)
1. Check all DTCs.
Are DTC(s) other than P0138 or P0158 present?
• YES —
• P2195 and/or P2197 DTC also present: Go to step 3.
• P0606 DTC also present: Go to step 4.
• NO — Go to step 2.
2. Check the A/F and O2 sensor values for the appropriate bank DTC Freeze Frame Data (FFD).
Is the AFS Voltage B#S1 = 3.35~3.70V AND the O2S B#S2 = 0.70∼0.90V?
• YES — Replace the appropriate bank Air Fuel Ratio Sensor ONLY (NOT O2 Sensor) to
correct the P0138 or P0158 DTC condition.
• NO — Inspect the O2 B#S2 circuit for open, short, or high resistance. If no trouble is found,
refer to TIS, applicable model and model year Repair Manual for P0138/P0158 diagnosis:
• 2005 Avalon:
Engine/Hybrid System – Engine Control – “SFI System: Diagnosis System”
• 2006 / 2007 / 2008 / 2009 / 2010 Avalon:

Diagnostic Procedure (Continued)
3. Inspect Air Fuel Ratio Sensor for the appropriate bank.
Does the Air Fuel Ratio Sensor have an open or short on the A1A+ or A1A– wires?
• YES — Repair the harness and revaluate the Air Fuel Ratio Sensor operation. Confirm
the previous DTC(s) do not reset.
• NO — Replace the applicable bank Air Fuel Ratio Sensor ONLY to correct the P2195/P0138
or P2197/P0158 DTC condition. Test drive the vehicle to confirm none of the previous
DTC(s) reset.
4. Inspect Oxygen Sensor 2 Freeze Frame Data (FFD) values.
Is the O2S B#S2 voltage more than 1.10v and/or the O2S Impedance B#S2 more than 300 ohms
when engine is at normal operating temperature?
• YES — Inspect O2 B#S2 circuit for open, short, or high resistance. If no harness issues are
found, replace the appropriate bank O2 Sensor ONLY to correct the P0606 DTC.
• NO — Follow the Repair Manual diagnostic procedure for P0138/P0158 DTC:
• 2005 Avalon:
