GM ACDelco Original Equipment 12681993 Intake Air Pressure and Temperature Sensor

Works as it should. I have been using this for a year and have had no issues. I keep one in the glove box as a spare

Learned on a forum that this part is a regular maintenance part to be cleaned as often as you change your oil on a 6.6l Duramax. This is due to the EPA requiring the truck to Crap in its own mouth. IE venting EGR gasses into the motor... Well when i pulled my sensor out of the 2022 model year truck with 26k miles on it, it was fully clogged with soot. Tried the $10 can of MAF sensor cleaner, didn't get it off. So decided to buy a new one, seeing they are cheap. Who what a difference! With changing it out, this morning my fuel economy increase by 1.0 MPG. No joke! I have a 100 mile round trip drive, and use Cruse Control every morning, so variables are the same other than temp/humidly by minimal amounts. I would recommend ordering one if you have the same truck and swap them out every oil change. I plan on it. Note: if you are trying to clean it, don't use a brush, as you will break the small little sensor.... Update: 1 year later... Repurchased this thinking I would receive the same product. I received instead a counterfeit/non-GM part in a clear plastic bag. original cam in a GM Delco box, with GM logo molded in part. The new one did not have the molding GM logo and part number. This is required by GM of all GM authorized parts. How do i know, I am a GM parts supplier. Do not buy from this supplier. You are not getting what you are paying for.

Works as intended for a 2022 Chevy duramax.

2021 chevy 3500hd duramax. truck has 20,000 miles on it and this little sensor was caked with soot. thanks to our wonderful government mandated regulations. just disconnect your batteries, one bolt holding in the sensor and swap, reconnect batteries. super easy install. will replace every 20k miles.

Bought to replace original sensor. GM and their infinite wisdom to follow federal guidelines of stupid diesel emissions, put an EGR on their engine. Th exhaust gas soot gets on the sensor and makes the truck run funny. Replaced sensor, problem solved. Thanks GM!
