I recently installed a set of glowshift gauges in my 2002 F-350 and after i installed them I went to try them out, truck started great but SES light came on and no throttle response.
Steps taken - Checked all the fuses - everything seems okay and all gauges still work.
- Plugged in a computer and got code P0122 = low input voltage to TPS
- Un hooked the connector to the TPS and tested the wires individually,
all wires test out okay besides
the 5 -volt reference wire. i have no reference signal to the TPS from the PCM.
- Any ideas before i go and take apart the connections and try to test the wires from the PCM or the PCM itself???
Hopefully im missing something simple
