2000 Toyota Avalon XL 3.0L MIL Lamp on
Posted to Asian Driveability on 9/21/2004 8 Replies

Code p0171 is reoccuring after clearing. No performance issues. have performed a/f sensor test and checked for vacuum leaks.

I suspect that a/f sensor is faulty but cannot prove it since light only seems to occur when customer is driving vehicle.
