Hi. I am have a problem with tps the signal wire has a steady 5 volt going to computer. Which in turn is making jeep rev high. It started with. Check engine light coming on then it would stall when took foot of gas. One week later started to rev at 2500 rpm and would not drop. I have replaced computer and I am in the process of trying to see if something with wiring. I was also told it may be acceletor switch by gas pedal. Any thoughts would be much appreciated.
