P1170, P0130, P0171... what would you do?

[greenrover666]

P1170 Downstream fuel trim malfunction (bank 1) Front sensor aged - rear HO2S adaption too lean/too rich LH bank.

P0130 O2 sensor circuit malfunction (bank 1, sensor 1) Front sensor LH bank stoichiometric ratio outside operating band.

P0171 System too rich (bank 1) Multiplication injector adaptive fuelling - rich limit exceeded LH bank.

All four O2 sensors, Cats, MAF, and air filter all about a year old... maybe driven about 5mos total.

Yesterday I replaced the water pump and the plug wires.

Not really sure what she needs though.

Thanks in advance,

Louis

Was the MAF replaced with an entire unit or just the sensor on the side? Was it new? Is the O-ring on the MAF?

 

[greenrover666]

Yeah, I believe I recall the O-ring present... and then MAF was from you as an entire unit.

Thanks!

What kind of air filter do you have on the truck? Has the truck been in any water since the new items were added? Lastly...when you clear the codes do they come back immediately....?? or under any special situation?

I would clear the codes, swap the front sensors to see if you get the error on Bank 2 afterwards.
