Hey guys quick question for you all in regards to some error codes I have on my bike, I am currently at work so I cant look into them all to much at this time, just trying to trouble shoot some stuff so I am ready when I get home. first off let me say that I have a 2010 road king with a modified stock pipe that is set up as a 2 into 1, with a stage one air cleaner with a PCV, I am currently running map M15-011-029, that dynojet recommended based on that same info I just told you. this morning when I pulled in to work I noticed that the check engine light came on on the bike so I checked the diagnostic codes and came back with
P0134 Front oxygen sensor inactive
P0154 Rear oxygen sensor inactive
P1003 System relay contacts open
P1510 EFI limited performance mode
P2138 TGS correlation error ( twist grip sensor)
P0031 front HO2S low/open
The first 2 codes I know why those are there since with the PCV they tell you to unplug the connectors on the sensors, the other ones I have no idea the reason why they came about, bike is running fine with no issues on it. any help or advice would be appreciated on what my next step should be. thanks gents

 

Have you cleared all the codes and then checked them again? If not, do it. Some might go away. I had a whole bunch. Cleared them and the only ones that came back were lighting related - due to the LEDs.

 

I have not done that just yet, as I said I was coming in to work and looked at them before walking in, haven't had the chance to go out and look at it yet, as soon as I am able to though I will and see if they go away.

 

P1510 EFI limited performance mode
P2138 TGS correlation error ( twist grip sensor)
These 2 are probably related. Pull the connector off the throttle body clean and lube with dielectric grease and clear the code.

The other p0031 is an 02 sensor problem, may need replacing.
If you do a search there's plenty of info out there about these codes.
Good luck

 

i dont have the green connector anymore. Been out for a few years with the wires soldered together

 

Wires on 02 sensor? Or EFI connector? The EFI connector is the one just behind the AC in the picture

 

This^^^

 

just an update. The codes cleared except the P0031 that one had come back. The bike ran great on the way home. This morning I started it up for ready to ride in to work and it was jerking pretty bad in first as though it was going to stall out. Check engine light came back on, haven't had a chance to look and see what code/codes came up with it as I was already running late for work. Will check when I get home. You guys think these issues could be coming with the PCV?

 

I have the p0031 code and p0134 after fitting forward front pegs , is this a major fault or easy to fix , thanks
