Trouble code p1640 and p0171
Had a mishap with the AC compressor clutch over the weekend that left me with a SES lite on. Pulled the codes and got two
P1640 - QDM1 - Failure
P0171 Bank 1 - System too Lean.
Can Anybody Translate these for me????
Thanks
Steve

p1640 = Controls low speed fans and something else....don't remember what right off hand.
p0171 = Lean code...just what it says.....test your o2 sensor or replace it per the hayes manual.
You can also look in tech info also for tips and pointers with these codes....pretty common ones around here I think.. I know I've had both, I still have the QDM 1 once in a while.....

Bill is right, P0171 can be a lot of things. In my case I keep getting that code because I have a vacuum leak somewhere. So check all your lines for cracks.
