Guys I’m new to this,

      My truck (2000 ram Cummins) is throwing p0122 on the dash, and p0222 on the scam tool.  Just changed and cleaned the battery terminals, also changed the tps, now I’m lost.  I did the whole disconnected battery’s and when I turn it on the p0222 is still on.  When I drive it, the truck jerks when I’m just cruising, if I stomp on the fuel it drives fine. WhT do y’all think It could be?  
 

Anything helps

Could be the other grounds, and there are alot of them. Or the 5v supply from the ECM. I have had several apps codes thru the years and it never turned out to be the Apps. I suck at electrical issues but my bet is on anything but the APPS. 

 

Also, disconnecting the battaeries will NOT clear a trouble code. You need a code reader/scanner to do that.

I drove the truck yesterday morning.  It seems to run fine at first, but as the engine warms up it  starts to buck and jerk as if it is slipping in and out of fear, but the code still comes up as the p0222

If youngomtomthe articles section under 2nd gen 24v, obd error codes you will the diagnostics for the 222 code. Also if you the oe tps sensor that could be the culprit. A timbo apps is a much tps sensor. But I would check out the code diagnostics before just throwing the part at it.
