Greetings viewers. In this video I dove into a 2014 Chevy Express with the 5.3L engine having a check engine light illuminated and stored codes P0172 and P0175. Flow along for a quick refresher on diagnosing these common fuel control faults and find the cause and make the repair.

Hey Dr.
What are the numbers that we need for the mass air and trim I heard you say zero on the trend what about the mass air flow sensor what's the number thanks good video
I'm also having the P0172 problem. Hope your video can help me to solve the problem. Thank You. don't forget to watch my channel too. and subscribe. thank you very much.
Great video my truck is acting up but has code p0172 and p0175 and running odd sounds like this is my problem
nice job but i would have rinsed the air box off with water on outside and inside od air box and dried off before installing back in. it takes a little extra time but shows you go above and beyond and makes your work look clean and good but thats just me.
Would the 2010 4.8 Silverado motor fall in this category, keep getting po175 172 codes
Thank you for sharing this video. I'm going to try it out. Since I have the same problem.
I have a problem with my 1997 k1500 when I hit 80 and up it will feel like my transmission slips and then selinder 3 misfires and when I let of the gas it goes back to normal know what that could be?
Nice job as always,thank you.
Hi Do you need some great lighting upgrade for your car to help you better driving, off-road and adventure.We're the pro auto lighting manufacturer for nearly 20 year and we're looking for sponsorship!
Good fix good to see you posting again god bless .
"With reindeer"! Not Rudolph!!
MAf reading was 6.2 after replacement which wasn't a whole lot lower than the 6.7 reading on the old one. Do you think just clearing the alcohol calculation would have fixed it?
Thanks for the video. That air cleaner assembly looks similar to my 2002 Express 5.0L. Most of the local auto parts stores don't carry that cylindrical filter anymore.
Good diagnosis! Thanks for sharing.
Thank you!!
Thxs Tim good info and repair…..
Another great video. Glad to see you posting again.
hate to see what happens when all that plastic gets really brittle. sure not the best way to secure that sensor for ease of service
Hi Doc greetings from Puerto Rico have a ? Got a 2004 trailblazer which doesn’t like gasoline every time I put gas has to be 10 to 15 cents at a time u have any idea what’s up Thanks
That airbox sensor assembly put up a good fight 😀
i'm sure there is a person payed to come up with stupid designs on purpose.
What was wrong with an airbox to throttle body tube with the sensor in the side.
Anyway, did you get some sausages?, nice in a sandwich 😀
Geebuz they don't make it easy to get apart do they ! Did the black water valve on our RV 4 week ago ended up cutting the grey water pipe just to get the friggin thing off and used a 2" rubber pluming gasket to reassemble , 4 friggin hours in 90+ heat outside no shade . Good thing was at the farm no one could hear me ….. lol …..
good vid doc
thankz
