What does the TP sensor do on a Jeep Cherokee?
The TP sensor provides the PCM with throttle plate angle info. This, in layman’s terms means that it tells the computer how much you’re stepping on (or off) the accelerator. The throttle angle info the throttle position sensor (TPS) provides is key to engine performance. So, when this bad boy fails, your Jeep is gonna’ resent it.
What do you need to know about the throttle position sensor?
The throttle position sensor (TPS) is used in fuel-injected and carbureted engines. The TPS is used to monitor the position of the throttle butterfly valve. When the car accelerates, the butterfly opens to allow air into the intake manifold. There are a few signs that could signal that the throttle position sensor is failing.
How to test the TPS code on a jeep?
Connect the black multimeter test lead on the battery negative (-) terminal. Turn the key to the ON position but don’t start the engine (this will power up the TP sensor). Your multimeter should report 0.4 to 0.9 Volts DC. If your multimeter doesn’t, don’t worry about it just yet, continue with the other steps.

What’s the problem with the throttle on a jeep?
I went back and they said that the throttle position sensor faulty and the entire throttle body needed to be replaced. So, they ordered one and installed it.

Why does my Jeep Wrangler splutter when I accelerate?
If your Jeep seems to run normally under low RPM,s however when you accelerate to pick up speed the vehicle starts spluttering and feels very under-powered, this section is for you. Before you run out and purchase a new fuel pump or throttle body, which can be quite pricy, start off by cleaning the throttle body thoroughly.
Why is my throttle position sensor not working?
The reason this happens is that the ECM doesn’t get correct information from the TPS as to how much to throttle the car. Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS.
What does it mean when your car throttles up while driving?
In these cases, the TPS isn’t providing the right input, the onboard computer cannot direct the engine to work properly. When the car accelerates while driving, it usually means the butterfly valve inside the throttle has closed up and pops open suddenly when the driver presses on the accelerator.
Why is the throttle not working on my Jeep Wrangler?
Checked the connection at the throttle and the cable/throttle body is not sticking. If you push in the clutch and hold it for a second while shifting the vehicles rpms increase with out hitting the accelerator. No power… Jeep seems to want to stall after put into drive.

Why is my Jeep Wrangler running so rich?
The only explanation I have is that one of the old O2 sensors was causing the jeep to run rich, dumping more fuel into the cylinders. Then, when I shut the jeep off, there ended up being left over fuel in the cylinders, basically a flooded condition.
Your Jeep Wrangler 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.
Why does my Jeep Wrangler keep stalling?
One of the most common issues your Jeep Wrangler is likely to develop is a stalling problem. The most challenging part of diagnosing a stalling problem is reproducing the conditions that led to the stall in the first place. Stalls can happen at any time, and it can be incredibly jarring when it does happen.

Why does my Jeep Wrangler make a bubbling sound when I hit the gas?
My Jeep sputters, loses accelation and makes a bubbling popping sound when I hit the gas (also my RPMs drop). Sometimes this is accompanied by my check engine light coming on. In the past year I have replaced my:
