Hi I have a 2012 xtl 5 l, I’m currently having issues saying that tps sensor 2 has low voltage. It has put the truck into limp mode and showing traction control has been disabled, terrible fuel mileage, and running really crappy… I’ve changed the throttle body thinking that would fix the problem… still have the same issue does anyone know where tps sensor 2 is or anything that’s could resolve this issue.
Thanks Luigi

 

What specific codes are you reading? If you hook up Forscan or Torque or another live data reader, what do you see from the throttle position sensor?

Have you done the throttle relearn procedure?

 

im getting the code p0222 and po2122… I have not do the relearn yet but would that cause the low circuit voltage?

 

The sensor is built into the TB. If you changed it already with no DTC change, it may be the wiring to it that's damaged. All 6 wires are direct from the PCM.

 

that’s what I’m thinking. It says sensor 2 do you know what wire sensor two is?

 

I think with these 2 codes I'd be looking at the accelerator pedal with attached sensor.

 

Ford doesn't help us with the multiple names everything has. The manual calls that Accelerator Pedal Position sensor.

 

I did the diagnostics with the snap on tool and the pedal seems to be working correctly. I did find that the wire to the tps is a little kinked thinking it might be the issue gotta go buy some connectors and try to splice it see if it fixes the problem🤞🏻
