I want to say that that tube is the vacuum tube that goes into the cabin. Its this tube that feeds vacuum to the HVAC controls to work the actuators that open and close duct valves. I think the EGR valve might also get its vacuum feed from this tube. If its leaking the vacuum pressure in the system will be less than otherwise. If thats the case the EGR won't work properly. The EGR has a sensor on it to tell the computer its position and therefore the ammount of exhast gas its allowing into the intake stream. If the computer thinks its getting an incorrect reading from the EGR valve sensor it will turn on the check engine light.

If it is the case then I think that resetting the ECU will eliminate the check engine light, but it will come back on after a little while.

I'll try to fix that ASAP. Do you think that might be causing my revving problem?

Thanks!

And if that is the problem, what code will it be throwing? I didn't get a chance to get the codes pulled today, but will tomorrow.

Thanks!

I don't know much about what codes correspond with which faults. You'll find out when you get the codes checked.

Its possible that it is casuing a reving problem.

I have the same code upon installing a new TPS

Stick some multi meter probes in the terminals and see if the voltage is moving or get some one with a OBD scanner and check it. If you have a SVT tb on your car they probably gave you the wrong TPS. You could also take it off and try twisting it with your fingers you can feel it if it is broken it should go nice in smooth in what ever direction your tb twists it.

all it says is low input, I'm going to guess that it means low input voltage going into the sensor, or low input signal comming into the computer from the sensor.

the simplest thing that could be wrong is that there is a dirty connection at the sensor.

Take the plug off the sensor. I believe that the side of the plug with the wires is the side of the connector with the sockets and the prongs are on the sensor.

Get some electrical contact cleaner and spray both sides of the plug to flush out and disolve any junk thats in there. Don't be shy with the cleaner and make sure you get the cleaner sprayed into the sockets real well. Then take the plug and plug it in and pull it out, do that a few times. This way as the pins go into the sockets they'll rub each other clean. Then spray it out again. If you have some bulb grease, (I call it di-electric grease) with your finger, or something, with a dab of the grease on it, fill in the sockets with the grease and then wipe a little on the rubber seal but use only enough grease to make the rubber shiny (it will help it go together easier and help keep out moisture.

Then reset the conputer to clear the code and see what happens.
