Thank you for sharing this info. Definitely seems like the easy way to go until one is ready to dig into the motor.Its a plug in that shuts down the AFM.
Almost as easy as unplugging the MAP sensor on the brake booster. Not quite as free though.
Theyve been around for a few years already. I was thinking about getting one for my last truck but never got around to it. I bought that one new. A 2011 GMC 1500 crew. Pretty much the same truck as the '13. At 19K the #7 plug fouled and the truck started running like crap. It happened again a few thousand miles later. I think it was 29 or 39K miles they pulled the motor apart and replaced pistons and rings. It was using a ton of oil. It was better after that but the truck was probably the worst GM truck I ever owned. Hub bearings went bad, the side of the seat blew out before 20K, dash cracked in two places a year after I bought it. I kept it for quite a few years but after things started to fall apart I didnt really take care of it. Bascally I beat it like a rental. In the end I traded it in down in MD for the '13. Up until this oil pressure issue started I had no issues with this one except for a starter and the left hub bearing and both of those happened over the last 20 months. Truck rides nice. If they get this long block in without any crap I might keep this for at least another 2-3 years.
True.
I didn't know if there were any concerns w/just unplugging the MAP sensor @ the brake booster. Just trying to learn about the potential end arounds for this system.
I unplugged mine years ago. I just have to remember to pull codes every now and again as the CEL is constantly on. No other downsides that I've seen.
I guess for those that don't have a scanner to pull codes & don't want the CEL on, the disabler is a good alternative.
