Need help code ERROR p0171 or code [51 in the haynes repair manual]
I just bought a [96 grand voyager 3.3L. V-6] and the check engine
light is on. the major error/code is 51 or P0171. indicating: "A lean air/fuel mixture has been indicated by an abnormally rich correction factor." what does that mean and how do I correct the malfunction? |

This could be caused by many things, such as a vacuum leak, low fuel pressure or a failed O2 sensor. It would be easily diagnosed with a scan tool ( not a code reader ) and fuel pressure guage. |

(P0171) There is only one upstream 02 sensor for that engine and it will not determine front and rear lean/rich condition. Assuming that the engine is running good, (maybe a slight hesitation) and you are looking for a repair without having it properly diagnosed.....Replace the upstream 02 sensor. its probably the original one anyhow.
