code 51

[ben1be]

I`ve had problems with the cruiser cutting out and not starting. Thought it was a fuel problem, but when I ran the diagnostics I got code 51. Throttle position sensor, neutral start switch or ECU. This is a 62. Has anyone had any experience with this code?
Thanks in advance.

TPS sensor is the likely culprit. If you have an FSM they give a correct voltage reading at idle for the sensor. That is a good place to start.

thanks,
I`ve got the FSM and I`ll start there.

Sounds like the nuetral safety switch....does jiggling the shifter do anything? If not, ignore me.

Sometimes a quick cleaning on the backside of the TPS will cure a code 51 such as where the spring is located ,but you will need the FSM(such as you got) to know how to adjust it
