Step 2: Disconnect the negative battery cable. Disconnect the negative battery cable and set it aside. Step 3: Remove the sensor electrical connector.
What is a TPS sensor?
The throttle position sensor (TPS) is used to inform the powertrain control module (PCM) of throttle position. The PCM uses this information to determine control of various output devices, such as the fuel injectors, transmission shift solenoids, etc. Basically, the throttle position sensor is a variable resistor. Its internal resistance and output signal voltage change in relation to throttle position. Some common symptoms of a failed throttle position sensor include hesitation, poor acceleration, rough idle, increased emissions and an illuminated Check Engine Light.
What is the function of the throttle position sensor?
When you press down on the gas pedal, your throttle body unit's valve opens. This causes your throttle position sensor to adjust the engine intake manifold accordingly .
Where should the throttle sensor be mounted?
It should be mounted to your throttle body, which is on top of your engine. You should disconnect your negative battery cable before removing the sensor. This helps you avoid the risk of electrical shock or causing an error code on your engine control module.
Why is my throttle position sensor not working?
Code errors can cause your throttle position sensor to work erratically or incorrectly. Otherwise, you’ll need professional software to reprogram your sensor. This job is best done by a professional mechanic. If your sensor just needs repairs, it could be the result of faulty or loose wiring.
How to install a new sensor?
Install your new sensor by working backward through the removal steps. Start by installing the sensor using the mounting screws. Next, connect your sensor to your vehicle's electrical system using a convenient electrical connector. You should be able to easily push it together and hear a distinct click. Check to ensure a firm connection.
Why does my engine keep idling?
Similarly, if your engine struggles to idle efficiently, it could also be a result of a damaged throttle position sensor. Stalling, surging, or hesitating while idling all can be caused by this unassuming sensor.
Can you replace a sensor?
Completely replacing your sensor may be the best way to avoid future issues, but some issues can be easily fixed by reprogramming or repairing your sensor. Reprogramming or resetting your sensor can sometimes solve these issues. This step can also be necessary when you install a new sensor.
Is throttle position sensor a corrosion sensor?
Just like any other electrical wiring, your throttle position sensor is susceptible to corrosion and faulty connections. Once you’ve established the issue is with your sensor and that it isn’t a programming fault, check the wiring and connection points before purchasing a new one.

Why is my throttle position sensor bad?
As mentioned above, due to the engine’s inefficiency, poor fuel economy will be one of the inevitable bad throttle position sensor symptoms. The throttle position sensor works alongside other sensors to ensure the engine gets everything it needs to run smoothly.
Why does my throttle light turn on?
The throttle position sensor can gradually fail or all at once. It can be faulty due to many causes. In most situations, when there is an issue with the throttle position sensor, the Check Engine Light will turn on.
Can a bad throttle position sensor cause a slow idle?
However, do note that a bad throttle position sensor can cause inability to shift up, rough or slow idle and lack of power when accelerating. Driving with these symptoms will put you and other drivers around you in danger, so you should bring your car to a mechanic as soon as possible.
What does the accelerator pedal position sensor do?
Since the accelerator pedal position sensor is an electrical component monitored by the car computer, it will trigger a fault code on the computer when something goes wrong. You’ll be able to notice there’s a registered fault when the check engine light comes on.
What happens if the accelerator pedal position sensor is working inappropriately?
If the accelerator pedal position sensor is working inappropriately, it will have problems with fuel efficiency. Aside from sending the driver’s input to the throttle body, it stabilizes the throttle control.
What happens when you depress the gas pedal?
But if the accelerator pedal position sensor fails, the car’s ability to instantly accelerate or decelerate as the driver depresses the gas pedal will drastically reduce. This can cause road hazards as the driver does not have complete control of the vehicle.
What is an app sensor?
APP sensor serves as a determiner and connector between the driver and the ECU – basically the brain of a vehicle.
Why is my car not running on idle?
If your vehicle doesn’t run consistently on idle, there are chances that you have a faulty accelerator pedal position (APP) sensor. A perfect working APP sensor is necessary for good fuel delivery and consistent or smooth idling.
What does a failing APP sensor mean?
Like most electrical and mechanical vehicle components, a failing or faulty APP sensor will showcase a series of signs that will alert the driver that a problem exists in the system. “Accelerator pedal position sensor problems” are as follows;
What happens if you push a gas pedal with a bad sensor?
Depressing a gas pedal with a bad sensor will give delayed signals or burst varying signals, leading to poor gear shifting.
What happens if one sensor fails?
If one sensor fails the algorithms in the PCM or module are written to prevent accidents due to uncontrolled throttle events. If one sensor doesn’t work or doesn’t agree with the other sensor as it should, fail-safe mode kicks in, reducing or eliminating throttle response for safety purposes.
What does P2135 mean?
A decrease in your car’s engine performance can be a sign of a logged P2135 code. Don’t ever open the throttle body with your fingers, even with the engine switched off or with the throttle body removed. On some vehicles, this can ruin the throttle body mechanism so that it has to be replaced.
Can you clean a throttle body with your fingers?
NEVER clean the throttle body with your fingers or put your fingers into the throttle body for ANY REASON. Always use a brush, because if the throttle body plate is driven closed (like if the assistant releases the pedal) the throttle body will seriously injure your fingers.
