Can anyone help me with the P/N for the Cummins Throttle Positioning Sensor. I have had mine off afew times and cleaned it with electrical contact cleaner. It helps for a while, but it seens when it gets damp or cold like it is in MN. right now it acts up. I have no trouble with the shifting. I called Cumming today and they could not find the P/n. Any other thought. I have never taken it completely apart.
