1992 Pt CheckTrans lite Detroit powers down

[Troy Tikalsky]

Has the throttle position sensor been checked/replaced? Sometimes computers can
be correct.

Thanks Rob for talking to Randy. I'll look for his number.

The problem is intermittent which seems to us to say it is not the
air filter. Since it was Allison Transmission specialist who did the
work I would think they would know where all the ground connections
are but we will have S & S check that one. Code 21 means throttle
position sensor error or fault. Everyone says it is not the sensor as
it is an on off switch in the translator between the transmission and
the engine.

We will be on the road at 7 but I will try and phone him around 8 our
time. We don't know if they will let us stay in the coach or if we
will have to find a motel.
