2003 Nissan Xterra Question: After tune up (TPS Removed and Reinstalled) Won't Shift Out of Second Gear

 

Question

I had to remove the TPS in order to change the cap and rotor, I also changed spark plugs, wires, air filter, and fuel filter. When I drove the vehicle afterwards, I got code P0122, and P0300 which I checked were TPS and Multiple Missfire, I adjusted TPS and cleared the code with my reader. The check engine light no longer comes on, but the car still wont shift out of 2nd, and drops into 1st out of the blue. There were no shifting problems at all prior. Help Please!

    On most Nissans, there are 2 TPS connectors, a brown one for the engine and a gray one for the transmission. Be sure that they are connected properly. If you reverse them, then the vehicle will not run or shift properly.

    To be clear do you know which one goes top and bottom?
