Here you go: http://repairpal.com/OBD-II-Code-P0171-and-P0174
These codes refer to the following: P0171 system to lean bank 1
P0174 system to lean bank 2
Hope this helps.
Hi Katt,
What did this end up being? Was your engine running rough when the light was on?
Thanks!
Hi Katt,PO430 means Catalyst System Efficiency Below Threshold, PO340 means Camshaft Position Sensor "A" Circuit. And I know some DIY tool, maybe they can help u.
