SOURCE: Trouble codes P172 and P175 keep storing in

Check/replace air filter as well as the MAF sensor. The most likely cause is a dirty/bad MAF sensor often caused by a dirty air filter. Below is a list of possible solutions:

  • Inspect all vacuum and PCV hoses, replace if necessary
  • Cleanthe MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
  • Inspect fuel lines for cracks, leaks, or pinches
  • Check the fuel pressure at the fuel rail
  • Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced.
  • Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)

Trouble codes? If none, then check O2 sensor outputs and replace as needed. Could be a leaking intake manifold gasket if you get "lean banks" codes. This happens in cold winters, but fixes itself in Spring.

How do you reset the check engine light on a 2003 gmc yukon xl


the check engine light means you have a trouble code in your vehicles computer. After fixing the problem with the yukon the check engine light can be reset sometimes by disconnecting the battery and disconnecting the ECM fuse. Although some parts stores are known to check your codes for free they might also clear them with a scan tool.

I am not too aufait with these types of vehicles, but I can ssure youo that trouble codes can be found online. Go into Google.com and enter GMC trouble codes. I can't from where I am because the sites are currently blocked from viewing.

Despite that, what are the symptoms the vehicle is giving with these trouble codes?
