Hi I'm brand new here but I've been a frequent snooper but I've finally come to a problem I can't find discussed before. The other day while driving my check airbag light came on it comes and goes but never stays for more than a minute. So thinking it had to be a sensor I went to oriellys and had my error codes checked only to reveal much more problems than I expected. The codes were: p0237(which I have had sinse I replaced my fuel pump so I think it's just faulty especially because the fuel gauge hasn't been right either i got another replacment I haven't had the time to install though),P0480,P0463,P0455,P0332,P0327,C0040,C0035,U1041, I think it pulled up 14 total codes but many were duplicates I think he said. my truck a SCSB 4.8 with the work trim 2005 model and just under 145,000 miles The oriellys guy suggested it may be a failing ECU and after a little research I'm thinking he may be right but I'd just like to see if any of y'all might have some ideas. Also the lights flicker like they did before I replaced my alternator and the voltage jumps around on the needle like crazy but I think I may have just picked up another faulty part butluckily that can be replaced under warranty. Other than the flickering lights the truck doesnt show any obvious signs of problems. Any and all help will be greatly appreciated needless to say it ruined my evening yesterday hah
I have a 2006 GMC 1500 Sierra 4x4 5.3 gas engine.
Okay, to my knowledge i have done everything that i could think of. I need some help. I am having a ABS problem that I cant figure out. I am getting my ABS light on my dash. I found out that I have codes popping up that is pointing towards both of my front left and front right speed sensors. About 3 months before, i replaced both of my front hubs with the same brand speed sensors. When the light started to come on and I found out that the codes were pointing at them. I took both of the speed sensors to exchange. that didn't fix it. I have disconnected the battery and unplug them waited for 5 minutes plugged everything back up. No fix! I replaced on of my hubs just to see if that would work, in which it didn't. Now that I have been deployed for a couple of months now, I am starting to think of other things. I know my ABS still works so my ABS is not disabled once so ever. Everthing on my truck is working just fine. I don't know how many times i have cleared the code myself. It still pops up.
I just don't know if the EBCM, ECU, or any other control modules on my truck that could be causing this code to pop up. I kinda don't want to replace them> ($$$$$$$$)
I was also wondering on a GMC is there another place on my truck that the code could be coming from?
I have read plenty of other problems that others are having. I even helped others. Either way none of them have helped me.
