Ive had this part replaced 2 times in one yr....now again the slow engine light is on....this time I called gmc.....what a night mare.....I've researched this and apparently it's been a problem since day one.....has anyone come up with a solution cuz the 2 chevy dealerships I've been dealing with can't figure it out....
Twice I've been going 75 mph and it slows down. Almost got hit by a truck...scared to drive it...
Thank for any info on a solution...

 

Welcome to the site.

I see the trouble code you listed, but exactly which part are you saying has been replaced?
If you are refering to the Accelerator Pedal Position Sensor, I don't recall that there has been much mention of those on this forum.

 

Maybe this will help

Yes it's the app sensor...when I researched I put in app sensor in google and I found lots of people have had the prob with all makes of cars....

 

That sorta helps...but my reg machanic checked that...he even reset the code and took a hose and let it run to see if water was coming in at every angle..didn't find any thing...I drove it for about a week and it happened again...he reset it...didn't happen for 7 months...now it's on again....thanks for your help...
