OK i started to get a tops sensor code. So went out and bought a brand new one and put it on calibrated it same problem. So then i got another oem one and it worked fine for a few months and again tps problem. What confused me is i got a chipped p28 and the other day my boy was throwing a bunch of wierd codes (not tps sensor) and i was like let me put my ecu in and see what happens, well he only throws one a damn tps sensor. So my question is could my ecu have a bad something causeing a tps code and is there any wiring i should check cause the guy before me hacked in a afc controller.
