Recently I've been having problems with my TPS on the LF and both rears. RF always comes on fairly quickly, but often the LF and both rear sensors/senders are not working. Even when they do, they will sometimes "drop out" after a short period of time.

Thankfully no codes yet, ECU has been reset, could it be the batteries in the senders?

 

About Kansas, the TPS started reporting correctly.

Perhaps the batteries needed shaking up (anyone who hasn't driven mid-west highways probably won't understand).
