I have a 2010 Street glide, 96ci with andrews 48 cams, tts mastertune, seac and recored 2-1-2 stock exhaust.

My check engine light came on yesterday with the following codes

P1510 EFI Limited Performance Mode

P2127 TGS2 Low/Open

P2138 TGS Correlation Error (Twist grip sensor)

Now I am running 14" wild one chubbys and did all the wiring myself. Ran just fine for 2 years or more now.

I did have the bike go into limp mode several times couple of months back and think its time to replace that ecm plug. I have silver connectors and have heard harley updated to gold connectors for better connection?

Could this be from the ecm plug connector needing replacement or is it more than that?

Appreciate any help.

 

uugghh. searched before posting and nothing showed up. Search from google and plenty show up from this forum. That search feature is so hit or miss at times. Anyways, think I found it. Ill check the ecm connector to make sure there is no corrosion on the pins first and see how that goes.
