Where is thetps located?

P1296 CHRYSLER - 5 Volt Reference Voltage Missing At Throttle Position Sensor

Hey DonAld, these are not hard to replace..( I do not know which engine you have..it makes a difference!! ).. take a PICTURE of where the current TPS os positioned and located... the radial (adjustment) location IS critical!!..
here is a link to Autozone, ...O'Reilly's, and Advance Auto should have one too..

The 2004 nissan titan is drive by wire, meaning there is no cable to control the gas pedal to throttle.
This system is computer controlled with a motor at throttle body and pedal sensors.

the TPS throttle position sensor is located inside the throttlebody . on most of these the complete throttle body must be replaced as there is no sperate tps sensor it is complete,
i would check and make sure this is the problem . GM started making TPS replacement sensors for there throttle bodies.

yes that is why it smoke and yes for theTPS

"TPS" stands for Throttle Position Sensor. It is located in the same place that all TPS sensors are located - on the throttle body.

A THROTTLE POSITION SENSOR (TPS) is usually located on the butterfly spindle so that it can directly monitor the position of the throttle valve butterfly.
Throttle actuator control(TAC), that code comes from that part of the system too.

The Throttle Position Sensor, or TPS is connected to the throttle shaft on the throttle body.

According with the Grand Cherokee Repair Manual, check this removal & installation procedure...
(see Figures 5 and 6)

1. Remove the air intake tube at the throttle body.
   
2. Disengage the TPS wiring connector and remove the two mounting screws.
   
3. Carefully remove the TPS from the throttle body.

To install:

1. The throttle shaft end has a tang that can be fitted into the TPS two different ways. Only one of the installed positions is correct. When correctly positioned, the TPS can be rotated a few degrees. To determine correct positioning, place the TPS onto the throttle body with the throttle shaft tang on one side of the TPS socket. Verify that the TPS can be rotated. If the TPS cannot be rotated, place the TPS on the throttle body with the throttle shaft tang on the other side.
   
2. Tighten the two TPS mounting bolts to 60 inch lbs. (7 Nm) and engage the wiring connector.
   
3. Manually operate the throttle and check for any binding.
   
4. Install the air intake tube.

Hope this helps; just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment. Thank you for using FixYa.

i change the tps sensor but stell do the same

The Throttle Position sensor (TPS) is a potentiometer that provides a voltage signal to the PCM that is directly proportional to the throttle plate position. The sensor is mounted on the side of the throttle body and is connected to the throttle plate shaft. The TPS monitors throttle plate movement and position, and transmits an appropriate electrical signal to the PCM. These signals are used by the PCM to adjust the air/fuel mixture, spark timing and EGR operation according to engine load at idle, part throttle, or full throttle. The TPS is not adjustable.

Hope thios helps (remember rated this).

did you check for vacoum leaks?
