Can a dirty throttle body cause a patriot to stall?
These were just some of the most common ones. A dirty throttle body can lead to stalling in your Patriot. If you let off of the gas coming to a stoplight and it stalls for a second or two and recovers itself, it very well could be a dirty throttle body that is causing the problem.
Where is the throttle position sensor on a Jeep Patriot?
Your Jeep Patriot uses a series of complex sensors to report what is going on to the ECU. The ECU then uses this information to adjust the timing, air fuel mixture, and more. When one of them goes wrong, it can lead to stalling for sure. Throttle Position Sensor – The throttle position sensor is typically located on the gas pedal.

How does the accelerator pedal work in a car?
Today’s modern cars, trucks, and SUVs are all equipped with an electronic throttle control system that contains an accelerator pedal position (APP) sensor. This sensor’s primary job is to monitor the position of the throttle pedal and send an electronic signal to open the throttle body as you depress the gas pedal.

Why is the right foot called the gas pedal?
When the light turns green, you don’t have to take off as quickly as possible. That pedal under your right foot is called the “gas pedal” for a good reason. The more you press down on it, the more gas you’re pumping into the engine. Press lightly on the gas pedal, and you’ll still accelerate, and you’ll still get where you’re going.
Although this device often lasts the entire lifespan of your vehicle, there are occasions when it will fail, wear out, and need to be replaced. The APP sensor essentially tells your engine how fast or slow to drive when you press the gas pedal.
How to troubleshoot the throttle position sensor ( TPS )?

Altima QR too. Good question…..if the motor was not revving up and the car won´t move, seems the TPS at the acc pedal assembly, is faulty..but the SES light should be on. This experience was with a friend’s car of mine…
What are the symptoms of a bad throttle position sensor?
This is another failure mode of the TPS, which indicates that it is falsely limiting the power being requested with your accelerator pedal foot. You may find that your car will accelerate, but not beyond a speed of 20 – 30 MPH. This symptom often goes hand in hand with loss-of-power behavior.
Can a bad TPS cause an engine to shut off?
Acceleration issues: A bad TPS may cause all sorts of power issues. Your engine may start up but it will have little to no power and it causes it to shut off. Unstable Engine Idle: Faulty position sensors can cause sporadic idle conditions due to fluctuating airflow.
Today’s modern cars, trucks, and SUVs are all equipped with an electronic throttle control system that contains an accelerator pedal position (APP) sensor. This sensor’s primary job is to monitor the position of the throttle pedal and send an electronic signal to open the throttle body as you depress the gas pedal.

Why does my Nissan Sentra not accelerate when I push the gas?
If your Nissan Sentra won’t accelerate, that is a serious cause for concern. There are a lot of different reasons that can cause this. Diagnosing the issue can be narrowed down by whether the engine is still revving when you push the gas or not. There is a section for each scenario with likely causes for each.
Why is the timing chain on my Nissan Sentra not working?
The timing chain (or belt) is responsible for keeping the upper valve train synced with the crankshaft. This is vital for spark timing. If the timing is off a little and the engine still runs, the timing belt may have skipped. If it has jumped too much the Sentra may not even fire.
