APPS/TPS acting up

[Shadrach]

I took my Travel trailer out to the dump station last weekend to empty and flush the tanks out for the season. On the way there I felt the pedal go dead a couple of times and after I started it up again it went into limp mode, would only idle. I shut it off and read and cleared the codes. P2121 and P2122. It worked fine on the return trip home. I haven't driven it since.

What causes the voltage to be low? Is it just worn out and will give more problems in the future? Does anyone know about Wells Vehicle Electronics? https://www.youtube.com/watch?v=jdaRDZMDuMQ or should I go with Genos?
Thanks in advance David

I've had a couple of trucks where the TPS, throttle position sensor gave me fits.... I found in some cases that using brake clean and spraying out the TPS would help it... in a few of the cases you wouldn't imagine the amount of dirt that rolls out... and in some cases this doesn't work and we'd end up buying a new TPS...

I have ordered one from Genos. David
