Hey guys I've been having some trouble lately with my XJ. It's a 98 with the 4.0. Every few weeks my CEL would come on and it was always coming up as P0122 which is throttle position sensor. It always went off the next morning though. I replaced the TPS twice in February 2015 thinking I had gotten a faulty unit.
This has been happening for a few months, but was hard to diagnose since the CEL always cleared itself. Last week it came on and stayed on though. Checked my code and it was the same thing. Went to NAPA and swapped it out for a new one. Jeep was running fine till the next afternoon when my CEL came back on. At this point I'm thinking there must be an electrical issue. So I checked it again and these are the codes that came up.
At this point I am lost. Electrical issues are not my strong suit. I am going to be adding an additional ground strap tomorrow, but other than that I don't know what else to try. Any advice would be greatly appreciated.
