Question

1999 Toyota Camry LE 2.2L with engine code P0171 and the check engine light is ON. What is the meaning of the code?

Answer 1

Hi there,

The P0171 code means there is a lean fuel mixture on bank 1. This can be the result of of an exhaust leak before the front O2 sensor, a weak fuel pump, leak in the intake manifold gasket or a problem with the front O2 sensor itself.
