It's been a long time since my last post, but I could use some advise on this topic. On the way to work this morning, my Road Glide went into limp-home mode as I was leaving a red light. The last five miles of my o-dark thirty commute was on the shoulder with my emergency flashers going. I down loaded the codes and this is what I got. 0445-Purge Solenoid High: 1511-Power Management Mode: 2135-TPS Correlation Error. First off, I believe that the 0445 is only related to a California bike with a catalyst and I have a 50 state bike; so I'm not worried about that one. The 1511 seems to be telling me that the bike went into Power Management Mode (limp home). The problem code, if I'm thinking correctly, is 2135 which is telling me that something in the system is not jiving with the throttle position sensor. I cleared codes when the bike cooled and the sun came up and after running it for a few minutes there are no more codes popping. (for the time being) Whenever I try to research these codes, it seems that everybody is interpreting the 1511 as the problem. I can't find much info on the 2135 code. I know that these bikes have these problems regularly, and I'm not unique in the universe, so I was wandering if anybody could offer any sage advise that may keep me away from the mechanic. BTW the bike is a 2008 Road Glide with a 103 kit and 255 cams. Thanks in advance for any replies.

 

Check the connector that plugs into the throttle body. Mine came loose once and caused the exact same problem. Check the pins for corrosion or anything abnormal....if you have a bit of dielectic grease, put some on the pins and plug 'er back up. It worked for me.

 

I had the same problem,same solution as gearhead.

 

2135 is one of the codes referred to in this SB.

My street glide has limped home twice. The first time the dealer said it was a loose conection on the ecm pins. It went 10 months before it did it again. This time they said it was the twist control sensor but after they replaced it the bike was still stuck in limp home mode. Now they are saying its the pins on the ecm again and Harley is sending a set of silver pins to replace the stock ones. It seems that Harley replaced the pins to silver in 2011 cause of all the problems. Still waiting on the pins to come in.

 

Have had this problem a few times over the past 3 years. Typically clearing the code did the trick. Yesterday, the code wouldn't clear and I came here to HDF and unplugged the ECM and plugged it back in. Problem went away. Thanks HDF!! I didn't have dielectric grease handy but will get some. The silver pins should have been a bulletin so anyone could get them replaced. Sometimes HD wants to keep the bike and let it run through it's courses before they just cut to the chase of what the historical problem has been. Go figure
