Raptor700 TPS Throttle Position Sensor Test, Replace, Install and Calibrate. Will it run now? Is it finally fixed?
Thiscould be from a faulty throttle position sensor or an unclean throttle plate or body. Clean the throttle plate and body and have the sensor tested to confirm the actual fault. If this fails to resolve the issue, a bad IAC valve, a failed EGR valve or an exhaust restriction could be the other reasons to cause this. TheTPS sensor is adjusted via the allen head screws on the side of the unit. As you rotate it you change the values and even a 1mm difference is huge at low RPM. I personally suspect that the reasoning you need or feel you need a setting of 9 vs let's say a 5-6 is where your's is at.Thethrottle position sensor (TPS) on your 3.3L equipped Nissan Pathfinder (Frontier, Xterra or QX4) is located on the side of the throttle body. As you can see in photo 2 of 2 (in the image viewer) the TP sensor has 2 connectors for a total of 6 wires coming out of both. This is due to the fact that the throttle position sensor is two sensors2 Locate the sensor as per the diagram above (thanks, sontakke!) 3. Disconnect car battery. 4. Disconnect old TPS. Press the plug to do this. 5. If you have the original TPS, use a Dremel or similar tool to make notches to unscrew the sensor. Those are screws, not rivets. 6. Remove the old TPS and put the new one.
First test the throttle position sensor. Most often, a bad TPS will cause the car to backfire and stall. To troubleshoot the problem, use a digital multimeter to test the signal. Then, test the connector, wires, and the connector of the sensor. If the signals sweep between zero and five volts, the TPS is bad.oMPu4fE.
