OBD II Codes

[lucho24]

Hi Everyone:

Can anybody tell me what these codes mean, I don't know if these means some sensors need to be replaced.

P1259 Manufacturer air metering
P0171 System too lean Bank 1

Thank you

P1259: Check the vtec solenoid. It is located in the rear passenger side of the engine. Pull it out, check it, clean it, plug it back in.

P0171: I would start off by replacing the fuel filter and the pressure regulator.


Sorry, I meant to post something for your old post but I never got around to it. I would look around online and see if you can find a copy of the service manual floating around for some detailed instructions because I dont feel like replacing my fuel filter right now!

I'm going to try it this weekend.
