2002 Honda CR-V LX with engine code P0171

Question

I have a 2002 Honda CR-V (LX) with engine code P0171, what is the meaning of the code?

Answer 1

Hi there,

This code can be caused by a few different things. The code is for a lean fuel mixture. Vaccum leaks, low fuel pressure, a faulty mass air flow sensor or a bad front O2 sensor can all lead to the lean fuel mixture code. Each will need to be tested to determine which is the cause.
