CEL code P0171
I have a 2009 Sante Fe V-6 with 32000 miles on it. At the recommendation of my dealer I had the tranny serviced and now I keep getting a P0171 trouble code. The CEL will come on and stay on for a couple of days then it goes out. The dealer says it's dirty injectors but I have my doubts. Are there any vacuum lines on the tranny that may be causing this? I'd appreciate any thoughts on this. Thanks!

P0171 is a lean condition in bank one (firewall side of the engine). It could be the injectors but it usually is something more simple like a dirty MAF or a vacuum leak (possibly the PCV). I'd first start looking for a vacuum leak or a leak in the intake tube between the MAF and the throttle body. Then I would clean the MAF.

Good point. Let Hyundai cover it under the 5y/60k warranty. Back in October (2010) my 2006 Kia Sedona with 53,000+ miles had a P0174 code (lean condition bank 2) and a P2187 code (lean condition at idle bank 1). The problem was a torn intake tube between the MAF and the throttle body. Kia replaced it for free under warranty.
