I have a 2021 trail boss 6.2 with 34k miles on it. The only aftermarket besides muffler delete is a pulsar lt. My truck went into limp mode and through a p2138 (throttle/position sensor) code. I cleared the code and it happend again a week later. Anyone have this issue before? Could this issue relate to the pulsar lt?
 
remove the pulsar for a few days. it very well could be the pulsar, so start by ruling that out.
 
Thank you. I removed it so we will see what happens. Anyone else have an issue like this when using the pulsar lt? I checked every forum that i could and i dont see anything.
 
Pulsar lt has been removed for about a month now and that appears to have fixed the issue. Now that its safe to assume the pulsar lt is the issue. How do we fix that? Is that something the manufacturer would diagnose and fix?
 
Thanks for letting us know what seems to be the solution to the issue you had. I’d suggest reaching out to Pulsar and seeing if they’ve had any other reports of a p2138 being thrown.
