Corvette Performance - TPS Signal = WHERE???

2001 C5

I've been searching on here and on corvetteforum, but cant find any posts that indicate where the tps signal is on this car? I guess I could take it right off the wire that hooks into the TB, but I would prefer to take it right off the PCM or under the dash like the tach signal.

Does anyone out there have a clue? Im really surprised I cant find this info.

Hmmm, I could try to tap into the APP (Accelerator Pedal Position) Sensor down at the pedal but it only reads from just under 1 volt at 0% tps to about just over 2 volts at 100% tps.

Hmmmm

You need to find a 5 volt reference. I think that the purple wire on the TB does that. I do not know where the signal wire is at on the PCM. I am waiting on someone to post as well.

On the 99 here is where I am running the WOT wire for my window switch. Not sure if that is what your looking for.

Nice wiring job. :lol: :lol:

Well all i can find as far as wires going to the computer on the blue connector are pins # 14 and 15 are both throttle actuator control circuit data. They are tan and 15 is orange/black. Maybe that helps ?

Are u looking for the tach output wire ? Or are u trying to find it like for a wot switch ?

Beer99C5 has it the TPS wire.

He also suggests using the light blue wire on the pass. coil pack for coil #6 for a Tach lead. I did that and got nothing but misfire codes and all sorts of problems. It was alot easier to get the white wire on pin 10 for a tach signal off the PCM.

Beer...yeah that is my last resort...to actually have to run it from the throttle body. Also, I appreciate the post anyway, but let me suggest that you rewire your setup and ditch the electrical tape. Go to the auto parts store and get one of the connectors that clip right on to the wire. It will come with another connector that you simply plug in to that wire.

DoesSpeed...there is a great location under the driver dash that has a rpm signal. For pics, do a search on corvetteforum. No need to go take the wheel off to get to the PCM and run a wire from the outside

Tried that too, you're referring to the group of 4 white wires? Yea, i never got a signal on any of those, the skip shift light never came on and the tach needle never pulsed. I probed all three of them, and nothing ever happened. I'll stick to going to the PCM, it was pretty easy.

The connection (as are all the connections in my Nitrous setup) are soldered, yes in the pic the tape is sticking up, this was easily trimmed after the photo was taken, and recovered with the plastic conduit when I put everything back together.

The connections I have shown work for me.

I am quite happy with them.

beer is awsome. His pics and knowedge helped me when installing my nitrous system.
