Fix code P0171

Fix code P0171 on Chevrolet Malibu, Pontiac Pursuit, and Saturn Aura, TSB PIP3310E

GM has issued a technical service bulletin (TSB) PIP3310E to address a check engine light and trouble codes P0171 on the following vehicles:

2005-2006 Chevrolet Cobalt
2006 Chevrolet HHR
2004-2006 Chevrolet Malibu
2005-2006 Pontiac Pursuit (Canada Only)
2005-2006 Saturn Ion with 2.2L Engine

GM has traced one possible source of trouble code P0171 to an unseated oil dipstick or air intake snorkel. When the dipstick is replaced in the tube but not seated fully, or the snorkel is not fully attached, the engine can suck in unmetered air, resulting in trouble code P0171. Ensure the dipstick is fully seated and the snorkel is properly attached before proceeding with any other diagnostics.
