How Do You Know if Your Accelerator Pedal Sensor Is Bad?
Last Updated on December 15, 2021
Though your car was running just fine the terminal time you drove it, information technology's suddenly interim really strange. The idle may exist surging, the car jerking while driving, and it might even stall out at a stop calorie-free. Your bank check engine light is probably on as well.

Without plugging in a code reader, it's a proficient guess you're having some sort of problem with the throttle position sensor. Here we go over how a throttle position sensor (TPS) works, go over the virtually common bad throttle position sensor symptoms, and provide some estimates on its replacement price.
How a Throttle Position Sensor Works
Every vehicle with an internal combustion engine has something chosen a throttle trunk, also referred to every bit a butterfly valve. This valve is positioned in the middle of the intake manifold and the air filter.
The job of the throttle is to manage the air menses that goes into the engine. As the driver steps on the gas pedal to accelerate the vehicle, more than air is needed in the internal combustion chamber of the engine.
While more air enters the engine, more fuel gets injected into it besides. The ignition of this mixture is how engine power is created.
The position of the throttle determines how much air enters the engine. There is a component in the fuel direction organization chosen a throttle position sensor which detects this position.
When you lot want to accelerate the vehicle, the sensor gives the throttle position data to the engine control unit. From there, the engine command unit will manage the throttle and permit information technology to take in whatsoever corporeality of air is needed in the engine.
The harder you pace on the gas pedal, the wider the throttle will open to allow more than air flow into the engine. At the same time, more than fuel volition be injected into the engine cylinders to create a balanced mixture for combustion.

Mutual Symptoms of a Bad Throttle Position Sensor
If you accept a bad throttle position sensor, then the engine control unit of measurement (ECU) will not know the position of the throttle. Every bit a consequence, the engine control unit will not be able to properly regulate the amount of air that enters the engine then that a successful combustion can exist fabricated. This volition ultimately touch on your driving ability to the point where it is unsafe to stay on the road.
When you have a damaged or worn out throttle position sensor, you lot will notice the symptoms of this problem right away. You might not know it is the sensor'south error, just the symptoms should motivate you enough to take your vehicle to the mechanic and find out what they think.
Chances are, they will tell y'all information technology is the throttle position sensor if you experience two or more of the post-obit symptoms.

#1 – Check Engine Alarm Light
The throttle position sensor is a central component of the overall internal combustion process. If this sensor goes bad, your engine volition ultimately fail to produce sufficient ability to accommodate your acceleration needs.
The engine control unit will detect this problem when it exists and then actuate the Bank check Engine alarm light on the dashboard. That way, you will be aware that your engine has some kind of problem that needs to be addressed.
Common diagnostic problem codes related to the TPS include: P0121, P0122, P0123, P0124, P2135, and P2138.
#2 – Weak Acceleration
A bad throttle position sensor means the engine control unit of measurement cannot manage the throttle position properly. The engine won't be able to receive the proper amount of air because of this. Whenever y'all go to advance your vehicle nether these weather, the dispatch will be very weak.
You'll be lucky if you tin can move the vehicle faster than 30 miles per 60 minutes. This will crusade you to consume a lot of gasoline, and ultimately ruining your car'south fuel economy.
#3 – Engine Rough Idling
When you stop or park your vehicle somewhere, its idle RPM should be somewhere in the vicinity of 600 to 900 RPM. If y'all notice the engine RPM below or in a higher place that range while your vehicle is stopped or parked, and so you lot take a rough or erratic idling trouble with your engine.
This may be due to a bad throttle position sensor if you've experienced some of the other symptoms on this listing.
#iv – Excess Fuel Consumption
Since the throttle position sensor has a major effect on proper air/fuel mixture for burning, inaccurate readings can cause besides much fuel to injected into the combustion bedroom. This will cause a rich air/fuel ratio which will result in poor fuel economy.
In addition, other sensors depend on accurate readings from the TPS. When that doesn't happen, those sensors will ofttimes compensate for too little or as well much airflow. The finish result is normally the need to go fill on gas more than frequently than usual.
#5 – Dispatch Changes
One very strange acceleration problem that can occur is increased acceleration without stepping on the gas pedal. You could be driving along on the road, and your car volition merely speed upward on its own out of the bluish. This tin obviously be very dangerous.
Out of all the acceleration problems that can occur, this particular one is a articulate indicator that the throttle position sensor is to arraign.
Replacement Cost
An engine needs the right amount of air just like it needs the right amount of fuel. If the engine does not receive the proper air amount, and so its internal combustion process is compromised. This ways inadequate ability generation and a whole list of other problems.
You won't be able to postpone this situation for too much longer. You'll have no selection but to go a diagnostic cheque done on your vehicle by a certified mechanic.
If it is revealed that your throttle position sensor is bad, and then y'all will need to replace it right abroad. The average replacement cost for the throttle position sensor is anywhere from $110 to $200. The parts cost is anywhere from $75 to $105 while the labor price is anywhere from $35 to $95.
In improver, you will accept to account for any extra fees and taxes that become added on too. Overall, you shouldn't take to spend more than $250 to get this replacement chore done. If you shop around for an cheap mechanic, you might find a lower hourly rate.
