Can a bad throttle body cause an engine to die?
A not calibrated throttle body can also cause this. You can calibrate the throttle body with most diagnostic scanners. The throttle body can affect the RPM the other way also. It can cause the RPM to be so low at idle so that the engine will die.
What to do if your Jeep Cherokee turns off while driving?
Try changing the throttle position sensor located on the throttle body. Pull throttle body off 4 bolts disconnect the 3 wires clean throttle body with throttle body spray or carb spray. Spray the other sensor clean to a shine. My jeep was doing same thing no more problems.
What causes the throttle to be low at idle?
It can cause the RPM to be so low at idle so that the engine will die. This is often caused when there comes a lot of soot and dirt on the throttle body flap, which will cause less air entering the engine and therefore cause a low idle RPM.
Is the throttle body dependent on other parts?
This is carried out electronically in electronic fuel injection engine systems. In most vehicles, there is only one throttle body, with a rare exception of special, larger vehicles. The function of the throttle body is also dependent on other parts, such as the air filter.
Why does my Jeep Cherokee start then die?
The fuel pressure would shoot to ~31 psi and then as the engine ran for its 20-30 seconds the fuel pressure slowly dropped to 0psi First thought was fuel pump. At this point since I’ve owned my jeep never have done a fuel pump (bought the jeep in 06-07).
Why is my throttle body injection not working?
When this automotive part is not working correctly, or its electronic sensors begin firing off readings to the onboard diagnostic computer showing problems, it can create car problems.
What to do if your Jeep starts and dies?
Replace the “new” injectors back with the stock ones and still had same issue, just sputters and dies. After looking at the fuel pump wiring diagram via AllData. Found out that between the fuel pump wiring and fuel pump relay there lies a Fuel Pump Ballast Resistor.
How to diagnose a jeep throttle position sensor?
Locate the connector that goes from the ECM (engine control module) to the TPS and disconnect it from the TPS. There are usually three prongs; the center prong is normally the negative connector. Take the volt meter and connect the negative side (usually the black wire) to the ground terminal on the battery.
How much does it cost to replace a throttle body?
Regular maintenance can effectively prolong the life of the parts of the throttle body and you may not require a replacement for a long time. However, when the fixing of the problem requires a replacement, you will have to pay on average anywhere between $430 and as much as $550 for the parts only for most vehicles.
What are the symptoms of a bad throttle body valve?
A bad throttle body valve can cause a lot of different symptoms in your vehicle. Here is a more detailed list of the most common bad throttle body symptoms. The throttle body has some angle sensors and other sensors installed inside of it.
Can a bad throttle body cause high RPM idle?
High RPM Idle The throttle body controls the engine’s idle to make sure it is always holding a steady RPM. If there is a problem with the throttle body, it may cause the be way too high. A not calibrated throttle body can also cause this.

What causes a misfire on the throttle body?
Misfires are easiest recognized as small bumps when you are revving the engine. The throttle body controls the engine’s idle to make sure it is always holding a steady RPM. If there is a problem with the throttle body, it may cause the be way too high.
Why does my computer move the throttle plate?
Depending on what the desired idle speed is the computer will move the throttle plate until the engine reaches the desired RPM. In a lot of cases, if you recently cleaned out the throttle body and this occurred right after it is because there is still debris in the throttle bore causing the plate to not move smoothly.
Why do the Revs go up when the throttle is off?
As you slowly turn it out it should begin to idle smoother and the idle speed should come up. If you have the correct pilot jet then before you get to 3 turns out on the fuel screw the idle will go up, peak, then start to slow down again. Set the fuel screw near where it idles the best.
Why does the idle go up after cleaning the throttle body?
The idle is going to be high at first until the computer relearns the idle again. Cleaning the throttle body allowed more air to enter the engine, and the computer is compensating by adding more fuel.
