P0171 P0174 P2195 P2197 – Toyota

Some 2005-06 Camry’s and Solaras may set any or all of these codes: P0171 P0174 P2195 P2197

P0171 (System Too Lean [Bank 1]), P0174 (System Too Lean [Bank 2]), P2195 (Oxygen [A/F] Sensor Signal Stuck Lean [Bank 1, Sensor 1]), P2197 (Oxygen [A/F] Sensor Signal Stuck Lean [Bank 2, Sensor 1]). The problem has been traced to a faulty Air Fuel (A/F) sensor.

If you have these codes, check your VIN code first because the problem covered by this TSB (#EG061-05)was corrected AFTER these VINS codes.

If you own a Camry with the 2AZ–FE engine, and your vehicle VIN is lower than JTDBE3#K#63048439, 4T1BE3#K#6U117608, or 4T1BE3#K#6U672386 then this TSB applies to you. If you own a Camry with the 1MZ FE engine and your VIN is lower than 4T1BF3#K#6U114144, or 4T1BF3#K#6U625167, then this TSB applies to you. If you own a Camry with the 3MZ FE engine and your VIN is lower than 4T1BA3#K#6U510428, or 4T1BA3#K#6U086954 then this TSB applies to you. If you own a Solara with the 2AZ—FE engine and your VIN is lower than 4T1CE3#P#6U671826 or 3MZ—FE engine and your VIN is lower than 4T1FA3#P#6U085959 then this TSB applies to you.

If you determine that your vehicle is included in this TSB, then replace the A/F sensor indicated by the trouble code with an updated part.

You need a professional shop manual to work on a late model vehicle. And you need access to the latest technical service bulletins so you don’t waste time and money replacing parts that may misbehave due to a manufacturer’s software glitch. Forget about those cheap manuals you find at the auto parts store. They will just lead you astray. Here are the two best online shop manuals around.

Eautorepair.net is really Mitchell On Demand with a consumer style interface.
Get a 1-Month subscription (31 Days) for $16.99, 1-Year (Best Value!) for $25.99, or a    4-Year (Best Value!) for $39.99. I like the wiring diagrams in Eautorepair.net better than the hard-to-read factory diagrams on Alldatadiy. However, Eautorepair.net doesn’t show how to remove trim or door panels. Alldata does.

AlldataDIY.com is simply Alldata with a consumer style interface. They have a different pricing model. But a 1-year subscription for $26.95. Add additional vehicles for $16.95 for a year. Or, buy their 5-year subscription for $44.95. Add additional vehicles for $29.95 for five years.
