Throttle position sensor not getting signal.

[ksoto033]

Hi there. I own an M1151a1, it wont shift out of first/second gear. Limp mode. I got it this way from Govplanet. Its giving me transmission code #22, ( low tps) when i test the sensor( wire 350c should read 5 volts. It there is nothing, and wire 355b should be ground but nothing either, when i go to the TCM the same wire 350a it does reed the needed 5 volt.
question? Whats in between the TPS and The TCM? Just the wire harmess?

You need to back up on that wire #350 to the TCM, as you stated there should be a 5V reference on that lead, check pin d (with underscore) wire # 350A at J1 at the TCM case, if you do not have 5V there then bust open the case and inspect the TCM and connections for water intrusion.

Thank you so much for your fast response, i do have 5v at 350a wire on the TCM, but nothing on TPS. Then it should be somewhere in its way to the TPS that this 350 wire its broken ? Shoot……, i dont know how am i gonna find where the wire its bad. Thanks again
