GM (CTS) Throttle pedal wiring

We want to use an electronic throttle pedal for a CTS on our driving simulators at work (they are pretty inexpensive). However I can't seem to track down a wiring diagram for the pins at the pedal sensor. It's a six pin male connector in a single row if that helps.

Thanks!

Year make model please

2004- 2007 Cadillac CTS

Thanks!

Accelerator Pedal Position (APP) Sensor

Pin - Wire Color - Circuit No. - Function

A - PU - 1272 - Low Reference

B - L-BU - 1162 - APP Sensor 2 Signal

C - TN - 1274 - 5-Volt Reference

D - BN - 1271 - Low Reference

E - D-BU - 1161 - APP Sensor 1 Signal

F - WH/BK - 1164 - 5-Volt Reference

Awesome! Thank you!

The funny part is I went into work to clean up my office and take some classes instead of sitting on the couch today, I clicked on the GRMs and ACTUALLY helped someone...

Can we get a picture of your simulator rig?

That's me driving :)

That's the prototype. We've sold one and have a couple more under construction. We mainly sell software, but this is an extension of the software and used for engineering vs. entertainment.

OK, I have another question about the throttle pedal I hope someone can help with. We have the throttle pedal out of the 2004-2007 Cadillac CTS. What kind of sensor is used? Is it a hall effect, or a potentiometer? How can I tell? I've put +5V in and only get resistance differences out, no voltage out of the Signal or Low Reference wires. Are all throttle pedals the same type of sensor?

Thanks!

I barely know something here-

Answering the last question- no, they are not all the same.

There's contacting, just a basic potentiometer, and non contacting- which I don't know how it works. On the latter, many of the smarter pedals have circuits in them to use the info.

Based on the wiring that JB posted, I would guess this is a former, but instead of looking for a resistance, you need to use the voltage bridge work, and all 3 pins- that's how they work, just like TPS's. The ECU's use the voltage information (since they are the ones generating the 5V anyway), not resistance.

Thanks, alfa,

Is there any way I can measure this with a voltmeter? Nuts and bolts I'm good with. Electrons I'm still learning.

Only if you have the 5V in.

I'm not good at electrons, either. But just know that these things work as voltage bridges. If it's a non contacting sensor, you'll never see resistance, but will see a signal if Vref, signal return, and signal line are all hooked up- you'll get a voltage signal that is correct relative to Vref.
