A throttle position sensor (TPS) is a sensor used to monitor the air intake of an engine. The sensor is usually located on the butterfly spindle/shaft, so that it can directly monitor the position of the throttle.
Where is the throttle positioning sensor located?
The TPS is usually mounted on the throttle body (the housing that contains the throttle valve).
What are the symptoms of a bad throttle position sensor?
- Car won’t accelerate, lacks power when accelerating, or accelerates itself.
- Engine won’t idle smoothly, idles too slowly, or stalls.
- Car accelerates, but won’t exceed a relatively low speed, or shift up.

Can you replace just the throttle position sensor?
When a throttle position sensor goes bad, your vehicle may stall or run rough at idle, and may stumble upon acceleration. The replacement of the TPS is a straightforward procedure that should take an amateur mechanic less than an hour to complete.
What happens when you unplug throttle position sensor?
The TPS as we call it is one of the most important sensors on the engine. Without it, the computer has no way of knowing when you push down on the gas or open the throttle. Best it can do it watch some other sensors and make some estimated guesses. On some cars, it may burp just as you unplug it if it’s running.
How much does a TPS sensor cost?
The average cost for throttle position sensor replacement is between $155 and $199. Labor costs are estimated between $55 and $69 while parts are priced between $100 and $130. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.
Can you drive with a bad throttle position sensor?
It is not a good idea to drive with a bad throttle position sensor. Driving your car in this condition can be dangerous because your car might not accelerate properly or could suddenly accelerate without the driver pressing the gas pedal.
What would cause a throttle position sensor to keep going bad?
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.
Will a bad throttle position sensor keep a car from starting?
Since any engine requires the correct air to fuel ratio and ignition timing to start, a faulty sensor can cause the engine to not start. … Faulty sensors can keep your engine from starting, but they are often engineered in to be a safety measure.
How long does it take to change a TPS sensor?
The throttle position sensor can be replaced without much trouble. It should not take more than an hour to take it out, replace it with a new one and test everything to ensure it is working.
How long do throttle position sensors last?
the average lifespan of a throttle position sensor is just over 80,000 miles, though some will last for the lifetime of the car. if a tps is suspect, a professional repair facility will perform electrical testing on the sensor.
Can a TPS sensor be cleaned?
During this process, the throttle position sensor should not be cleaned due to the possibility of contamination or wire damage. The best way to preserve the sensor is to remove and replace it after cleaning is finished.
What does a throttle position sensor look like?

Can a throttle position sensor cause misfire?
What are signs of a bad Throttle Position Sensor? Acceleration issues: A bad TPS may cause all sorts of power issues. … 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.
Is throttle body the same as throttle position sensor?
The TPS checks the amount of air/fuel mixture being delivered to the engine, while the throttle body temperature sensor monitors the temperature of the air/fuel mixture and the actual throttle body.
What sensor would stop a car from starting?
A crankshaft position sensor (crank sensor) is an important device measuring the engine RPM and tracing the crankshaft position. The car won’t start if the crankshaft position sensor doesn’t work properly. The crank sensor can fail, or its wiring can get damaged. This may cause the car to stall or not start.
Can a bad throttle position sensor affect transmission?
The Throttle Position sensor measures the throttle position, which is controlled by the gas pedal. It is used to determine engine load and if it fails it can cause automatic transmission shifting problems.
How do you test a throttle position sensor?

Can a throttle position sensor cause reduced engine power?
Faulty Throttle Position Sensor
When one (or both) of the sensors goes bad, the vehicle will enter Reduced Engine Power Mode.
What is the purpose of the throttle position sensor?
A throttle position sensor is used to measure how open the throttle valve is and therefore controls the amount of air which can flow into the engines intake manifold.
What controls the throttle position sensor?
The TPS sensor is a potentiometer, providing a variable resistance depending on the position of the throttle valve (and hence throttle position sensor). The sensor signal is used by the engine control unit (ECU) as an input to its control system.
