1991 Ford F150 V8 Four Wheel Drive Automatic 149000 miles
I am getting a code 122 and the automatic transmission in my truck is shifting hard. The truck has been recently shutting off while driving although it usually starts back up. I jumped the VREF and TP terminals on the TPS sensor wiring connector and received a code 123 so I replaced the throttle position sensor. I jumped the VREF and SIG RTN terminals and I have 5.06 Volts at the sensor connection. I am still having the hard shifting problem. When installing the new TPS sensor did I need to somehow adjust it before the installation? I am not sure what to do next?
