    Have a 2014 FFV CM platinum and I am not having a hard start issue like others have had with the same code but am curious if any of y’all have had the check engine light come on and at the same time got the traction control off message on your dash? If so, what was the fix? I have the aftermarket 46 gallon tank so I don’t want to add any gas in case the fuel pump needs to be replaced

    I’m going to clean the MAF sensor first and hope one of y’all knows what to do next

    the code said “system too lean (A/F lean, bank 2)”

    thanks in advance!

    Cleaned the MAF sensor yesterday. Does anybody know how many times the truck needs to cycle or how many miles it needs to be drives to see if 5)3 CEL clears itself?

    When I had MAF issues it was triggering both banks. I suspect you are having another issue.

    Unhooking the battery for 20 mins reset everything after reinstalling/replacing a MAF.

    Never been a fan of not concluding a thread that began with a problem.

    As previously stated, I cleaned the MAF sensor and disconnected the battery. This cleared the code momentarily and after about 200 miles the CEL was back.

    This time I had a P0171 and P0174 codes. I was pretty sure I had a vacuum leak as the truck started and ran find but was running lean. I found a hose on my aftermarket CAI that didn’t have a clamp on it and the hose was loosely on there. Put a clamp on it and have driven 800 miles and it the CEL light hasn’t come back. I appreciate the help and hope this helps somebody down the line
