There you go!

BTW, I have never bought anything off of GM Parts Direct. I tell the parts guy at dealership that GM Parts Direct has it for $XX.xx and they always match that price. So I get the GM Parts Direct price, without shipping, from the dealer. I've done this several times at two different dealerships and it's always worked.

 

Cool. And thats without GMPD's 15 to 25% shipping costs.

 

Get an update on OFN before I have to e-stalk you and resurrect the coolant flow debate!

 

Just as a follow up, I couldn't get any of the 4 dealers in my tri-city area to match GMPD's price but one of them did work with me to a point where I felt that their price would have equalled GMPD's price with shipping. I re-pinned my connector back to OEM config. and plugged the pedal in and it works flawlessly. Thanks for setting me straight, ya'll.

And there's nothing to update right now Bandit. The next update will be with paint and will be in the next few weeks.

Any chance if anyone could tell me if the 1997-2002 Corvette DBW pedal will work with a 2004 5.3 truck DBW set-up providing I am using the truck ecm, harness, throttle body, and tac?

The plugs look the same, didn't know if the wiring or actual function of the pedal was the same.

I really need some input on this if anyone can help me?

 

I do not believe that it will. I believe that one of the pot on the Corvette pedal sweeps 0 - 2.5 volts and the matching pot on the truck pedal sweeps 0-5v. Someone with Alldata could confirm this for you.

Ok Thanks,

I was looking at my truck pedal and it looks like it uses the same design of the pedal sensor as the corvette, I'm curious if this can be swapped over?

 

That I do not know. I think most of the sensors are built into the pedal and not easily taken off.

J. J.

 

ok thanks again,

Here is a comparison of the wiring , it looks like two wires at pin J and E need to be swapped around.

But now I need to know if the signals are correct for it to physically work

 

Those look like they came off of Alldata. If you have access go to the Electronic Throttle Control section and go to description. It will tell you the sweeps of the APP sensors. If they match you are good to go.

Or you can just switch those wires, plug it in and try it out. The computer will throw a code and not let the engine rev if they don't match. Then you'll know for sure.

I would do it for you but I only have Alldata DIY and I would have to pay for a subscription for both hose vehicles.

Edit: It looks to me as though you have more than just 2 wires to swap around.

J. J.

 

Thanks I don't have alldata, I got those off another site. Maybe someone could chime in later if they have it

Thanks again for you help

 

I have a friend with Alldata Pro. I'm getting him to look it up for me. Stand by ...

J. J.

 

cool thanks!

 

Had to step out. Get back with you in a few hours. Sorry.

J. J.

 

No Prob, thanks for your help

 

For the truck, keep in mind I don't know exactly what model you're pedal is from, I used 2004 2wd Silverado 1500 5.3L Vin T, non-hybrid:


THROTTLE ACTUATOR CONTROL (TAC) SYSTEM DESCRIPTION

The throttle actuator control (TAC) system delivers improved throttle response and greater reliability and eliminates the need for mechanical cable. The TAC system performs the following functions:
Accelerator pedal position (APP) sensing
Throttle positioning to meet driver and engine demands
Throttle position sensing
Internal diagnostics
Cruise control functions
Manage TAC electrical power consumption
The TAC system components include the following:
The APP sensors
The throttle body assembly
The TAC module
The powertrain control module (PCM)
Accelerator Pedal Position (APP) Sensor
The accelerator pedal assembly contains 2 individual APP sensors within the assembly. The APP sensors 1 and 2 are potentiometer type sensors, each with the following circuits:
A 5-volt reference circuit
A low reference circuit
A signal circuit
The APP sensors are used to determine the pedal angle. The control module provides each APP sensor a 5-volt reference circuit and a low reference circuit. The APP sensors then provide the control module with signal voltage proportional to pedal movement. Both APP sensor signal voltages are low at rest position and increase as the pedal is applied.

Throttle Body Assembly
The throttle body assembly consists of the throttle body, the throttle position (TP) sensors, and the throttle actuator motor. The throttle body functions similar to a similar to a conventional throttle body with the following exceptions:
An electric motor opens and closes the throttle valve.
The throttle blade is spring loaded in both directions and the default position is slightly open.
There are 2 individual TP sensors within the throttle body assembly.
The TP sensors 1 and 2 are potentiometer type sensors, each with the following circuits:
A 5-volt reference circuit
A low reference circuit
A signal circuit
The TP sensors are used to determine the throttle plate angle. The control module provides each TP sensor a 5-volt reference circuit and a low reference circuit. The TP sensors then provide the control module with signal voltage proportional to throttle plate movement. Both TP sensor signal voltages are low at closed throttle and increase as the throttle opens.

Throttle Actuator Control Module
The TAC module is the control center for the throttle actuator control system. The TAC system is self-diagnosing and provides diagnostic information to the PCM through a dedicated serial data line. The TAC achieves throttle positioning by providing a pulse width modulated voltage to the TAC, as directed by the PCM.

Powertrain Control Module
The PCM determines the driver's intent, then calculates the appropriate throttle response. This information is sent to the TAC module through a dedicated serial data line.

MODES OF OPERATION

Normal Mode
During the operation of the TAC system, several modes or functions are considered normal. The following modes may be entered during normal operation:
Minimum pedal value-At key-up the PCM updates the learned minimum pedal value.
Minimum TP values-At key-up the PCM updates the learned minimum TP value. In order to learn the minimum TP value, the throttle blade is moved to the closed position.
Ice break mode-If the throttle is not able to reach a predetermined minimum throttle position, the ice break mode is entered. During the ice break mode, the control module commands the maximum pulse width several times to the throttle actuator motor in the closing direction.
Battery saver mode-After a predetermined time without engine RPM, the control module commands the battery saver mode. During the battery saver mode, the TAC module removes the voltage from the motor control circuits, which removes the current draw used to maintain the idle position and allows the throttle to return to the spring loaded default position.
Reduced Engine Power Mode
When the PCM detects a condition with the TAC system, the PCM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
Acceleration limiting-The control module will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.
Limited throttle mode-The control module will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.
Throttle default mode-The control module will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.
Forced idle mode-The control module will perform the following actions:
Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned off.
Ignore accelerator pedal input.
Engine shutdown mode-The control module will disable fuel and de-energize the throttle actuator.


For the Vette, Vin G:


THROTTLE ACTUATOR CONTROL (TAC) SYSTEM





The throttle actuator control (TAC) system uses the vehicle electronics and components in order to calculate and control the position of the throttle blade. This system eliminates the need for a mechanical cable attachment from the accelerator pedal to the throttle body. This system also performs the cruise control functions.

The TAC system components include but is not limited to the following:
The accelerator pedal position (APP) sensor
The throttle body
The throttle actuator control (TAC) module
The powertrain control module (PCM)
Each of these components interface together in order to ensure accurate calculations, and in order to control the throttle position.

Accelerator Pedal Position (APP) Sensor





The accelerator pedal position (APP) sensor is mounted on the accelerator pedal assembly. The APP is actually 3 individual accelerator pedal position sensors within 1 housing. Three separate signal, low reference, and 5-volt reference circuits are used in order to connect the APP and the TAC module. The APP sensor 1 voltage should increase at the same time that the accelerator pedal is depressed, from below 1 volt at 0 percent pedal travel to above 2 volts at 100 percent pedal travel. APP sensor 2 voltage should decrease from above 4 volts at 0 pedal travel to below 2.9 volts at 100 percent pedal travel. APP sensor 3 voltage should decrease from above 3.8 volts at 0 pedal travel to below 3.1 volts at 100 percent pedal travel.

Throttle Body Assembly





The throttle body for the TAC system is similar to a conventional throttle body with some exceptions. One exception is the use of a motor to control the throttle position (TP) instead of a mechanical cable. The other exception is the new design TP sensor. The TP sensor mounts on the side of the throttle body opposite the throttle actuator motor. The TP sensor is actually 2 individual TP sensors within 1 housing. Separate low reference and 5-volt reference circuits are used in order to connect the TP sensors and the TAC module. The TP sensor 1 signal voltage increases at the same time that the throttle opens. The voltage increases, from approximately 1 volt at 0 throttle to above 3.5 volts at 100 percent throttle. TP sensor 2 signal voltage decreases at the same time that the throttle is opened. The voltage increases from approximately 3.8 volts at 0 throttle to below 1 voltat 100 percent throttle.

Throttle Actuator Control (TAC) Module





The TAC module is the control center for the electronic throttle system. The TAC module and the PCM communicate via a dedicated redundant serial data circuit. The TAC module and the PCM monitor the commanded throttle position and compare the commanded position to the actual throttle position. This is accomplished by monitoring the APP and the TP sensor. These 2 values must be within a calibrated value of each other. The TAC module also monitors each individual circuit of the TP sensor, and of the APP to verify proper operation.

Strangely, it does not list the sweep ranges for the sensors in the truck pedal like every other vehicle I've ever checked. But it does state that all sensors increase as the pedal is pushed. The 'Vette says that APP sensor 2 and 3 both DECREASE as pedal is pressed. Therefore, I am 100% certain the 'Vette pedal will not work for you no matter how you rewire it. Sorry.

well dang, that's cool...you save me a $100, I was getting ready to buy a corvette pedal.

I modded my stock pedal and it's ok, but the housing takes up more real estate than the vette so it would have been nice to swap out. But I'm ok either way.

Thanks again

 

NP. I have an '05 'Vette pedal I would sell very cheap if you know anyone it would help ...
