Re: Throttle position sensor 850 1995

The TPS on my ’95 850 failed at about 50k miles. The failure mode manifested as sporadic shifting at constant freeway speeds and loads. Removal and probing with a DVM indicated a discontinuous voltage (resistance) reading that got worse with temperature soak. Replacement solved the problem. Interestingly there were NO OBDII codes. The resistance readings were always within spec; the computer was interpreting the faulty readings as an erratic right foot and tried to compensate as best it could.

Kind of reminded me of HAL in 2001…
