Westwildcat posted a topic in 2014 - 2018 Chevy Silverado & GMC SierraI have heard that GM can tell of I have been speeding with my truck when they hook up their computer to it. Is that true? That's not really my issue, but somewhat related topic is can they tell i tried a burnout with my new truck? I did one for 5-10 seconds and am just wondering if that information can be read with their diagnostics system? Thanks!
Westwildcat posted a topic in 2014-2018 Silverado & Sierra TroubleshootingI have a question I hope someone can help me with. I decided to try doing a burnout with my truck today for the first time. I did one for about 5-10 seconds, or tried to with some success. Now I have a check engine light and the truck runs like $h!t. Wont get up to highway speed and transmission doesnt shift properly. When at an idle it runs rough. I tried hooking the obd2 test tool to the truck under the dash, and two codes come up. P228c - fuel pressure regulator P0089 - fuel pressure regulator. I tried the erase button and it did nothing. I attached 3 notifications I received when this happened. I'm going to take the truck to dealership tomorrow. Any ideas on what this is? Will warranty be void since I was trying to do a burnout? Any help or thoughts on my situation is appreciated. Thanks
that modern carpenter posted a topic in 1999-2013 Silverado & Sierra 1500Hey guys, I'm having a real tough time with my 2013 chevrolet silverado 4.8L V8 the engine is an L20 Vortec. I'm getting all these nasty fault codes and they are intermittent and usually start acting up when I'm driving in the city. When the engine is warm and I stop in traffic, or hit a crawl speed. The truck normally kicks into "limp mode" and all these fault codes start up ex. P2544 ( regularly) P150C, P069E, and recently P0700. now there is a list of communication codes, but normally its U0073, U0100, and U0109. I've gone to a few auto shops and they kinda said god luck, The dealer had no idea what i was talking about, started with cleaning all my grounds, as well as my fuses, everything seems to be in order. My brother (who is a mechanic) seems to think my TCM is at fault and not working, but I'm hesitant to call that the problem because Im pretty sure its in my transmission which seems like a fairly big job. Everything else runs fine and there is no problems at all when the truck isn't acting up. Any thoughts or suggestions? I'm pretty desperate to fix this as I plan on taking it to Alaska in july
Tyler_bland38 posted a topic in Hybrids, XFE, & Active Fuel ManagementI have a 2012 silverado and my check engine light keeps coming off and on. The codes read are c0900- device 1 voltage high(history) c0899- device 1 voltage low(history) p0300- multiple misfire detected (History Mil) p0301- cylinder 1 misfire detected (confirmed) there is a slight rough idle on the truck, and I think that my gas mileage has decreased slightly Does anyone have any idea what my problem could be before I take it to a shop, or start replacing parts
