My CEL came on today. Checking the codes, I get:

P2197 -- O2 Sensor Succk Lean, Bank 2 Sensor 1.

OK, where is bank 2, sensor 1?

2003 Accord, V6

Thanks

 

For your 03 Accord V6, I believe there is a Technical Service Bulletin (TSB) to reflash the ECM, which would be covered under the 8year/80,000 miles extended emission warranty. Has to do with tolerance range of the O2 sensors.

TSB #604 -- DIAGNOSTIC TROUBLE CODE P2195 OR P2197, LAF SIGNAL STUCK LEAN, V6 ONLY. *NM (NHTSA ID #10014139, JUNE 16 2004)

You may want to check with the dealer first. Even if you are over 80,000 miles, they may still possibly do it under goodwill.

BTW: Bank 1 is the side of cylinder 1, Bank 2 is the side of cylinder 2. Sensor 1 is the sensor closest to the engine.
