Does anyone know if replacing the mass airflow sensor on my 2015 Sierra 2500 HD with a K&N air intake stop my check engine light come on? Or can someone recommend a replacement sensor for it?

Well you never said what the check engine light is coming on for.

 

Check engine light codes will have a number, so what is that code number you are getting?

 

And each code number has a diagnostic chart that can be gone through to make sure you are doing the proper repair and not just shot gunning parts at the truck.

 

Also K& N filters on MAF vehicles has always been stupid in my eyes. The versions that are oil filters are nothing but problems because over time the oil wicks off the filter and starts to cover the MAF sensor wires, thus leading to sensor failure and incorrect readings. There is a reason by OEM's use dry filters on all cars, because they work time and time again.

Did you google that code?

 

It's for a NOX sensor on a Duramax Diesel. Has nothing to do with a MAF sensor.

      Scan Tool Recommendation

      By AndrewF · Posted

      I am in the market for a bidirectional scan tool so was hoping someone can help point me in the right direction. There are so many options out there it is hard to narrow down which make/model to choose.   I have always done my own vehicle work so looking to maximize capability with the scanner. Ideal price is $1k or less but would be willing to exceed if it opens up significant benefits.  Currently my 24 2500 is the newest vehicle but also have a few mid to late 2010s Subarus as well.    It seems that the Autel MP900 has a decent amount of features at a reasonable price?

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      By C/K Man · Posted

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.
