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 purpose of a throttle position sensor?
Throttle Position Sensors - The job of a TPS is to convert the throttle blade angle and throttle opening speed to an electrical signal that is sent to the PCM. The PCM then uses the electrical signal to determine engine load and adjust ignition timing.
How many volts should a throttle have?
Now open the throttle to the “wide open throttle” position, you should have less than 4.8 volts.
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.
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 .
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.
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.
How to tell if throttle position sensor is bad?
One of the most common signs of a defective throttle position sensor is delayed or poor acceleration. Delayed acceleration means that there is a considerable time difference between stepping on the accelerator and the actual acceleration of the vehicle.
How much does it cost to replace a throttle position sensor?

How long does it take to change a throttle body?
The price of the labor cost does vary heavily depending on the car model since, in some cars, you can change it within 5 minutes, and it can take several hours on others. Remember that after you replace a throttle position sensor or the throttle body, you need to reprogram/recalculate the throttle angle.
What causes a bad throttle position sensor?
A poor throttle position sensor causes a problem with acceleration, which in turn causes a problem with the automatic transmission. The throttle position sensor does also sends information to the automatic transmission control unit. If this information is faulty, there might also be a problem with your automatic transmission’s shiftings.
Can you replace throttle position sensor separately?
If you have a newer car with an electric throttle body, the throttle position sensor is most likely integrated into the throttle body and can’t be replaced separately.
How to tell if throttle position sensor is bad?
What are signs of a bad Throttle Position Sensor? 1 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. On the other hand, it can also cause your car to have spontaneous accelerations even if you didn't step on the gas. 2 Unstable Engine Idle: Faulty position sensors can cause sporadic idle conditions due to fluctuating airflow. If you see your car misfiring, Idling rough, or stalling out while you drive then you definitely want to have a professional check out that sensor. 3 Unusual fuel consumption: The TPS works alongside other sensors to ensure that your ride is driving smoothly and efficiently. When these sensors start to go bad then other modules might start working differently to compensate for lack or abundance of airflow. In most cases when your sensor goes bad, you will see the vehicle consuming more fuel than usual 4 Warning lights: The check engine light is designed to warn you when any sensor goes bad. If the check engine light turned on in your car, then it's important to check it out before the issue gets worse.
