Why Replace Throttle Position Sensor?

What happens when throttle position sensor goes bad?

Common signs include lacking power when accelerating, rough or slow idle, stalling, inability to shift up, and the Check Engine Light coming on.

Do throttle position sensors wear out?

The purpose of a throttle position sensor is to keep your car running like it’s supposed to by controlling the throttle. With the passage of time, the sensor will start to get worn and may eventually have to be replaced.

Is it bad to drive with a bad throttle position sensor?

Depending on the exact nature of your bad throttle position sensor problem, your car could be very difficult to drive, it could get stuck on the side of the road, or it could even accelerate uncontrollably – a very scary and dangerous situation!

When should I replace throttle position sensor?

This sensor can fail gradually, or all at once. In most cases, the Check Engine Light is illuminated if a TPS failure is detected. Once the TPS begins to fail, even partially, you’ll need to replace it right away.

How do you reset throttle position sensor?

The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.

What does it mean when your car struggles to accelerate?

Among the causes of poor acceleration are clogged fuel injectors and/or inadequate fuel pressure/volume. This can cause the vehicle to accelerate slowly, or even sputter and stall, especially at high speeds. A clogged fuel filter can also restrict the amount of fuel that reaches the injectors.

How much does it cost to replace a throttle position sensor?

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 cost is anywhere from $35 to $95. In addition, you will have to account for any extra fees and taxes that get added on as well.

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.

When I press the gas pedal it won’t accelerate?

The most common reasons why your car is having trouble accelerating is due to three main categories: Actuator Malfunction – bad spark plugs, faulty fuel pump, damaged fuel injectors, old fuel wiring, and other fuel component issues.

Can you drive without TPS?

You will still be able to drive without a TPS, though not very well. The ECU will see a lean condition from the o2 once to open the throttle and it will atempt to richen it up. The ECU will also know how much vacuum your are pulling by the MAP sensor and will adjust fuel and ignition acordingly.

With the engine running, the position of the throttle plate (along with other sensors ) tells the computer how much fuel the engine needs at any given moment. Fortunately, it’s not that hard to test the sensor. You can use the position sensor operating characteristics to test it using a digital multimeter (DMM).

How do you reprogram a throttle position sensor?

Make that the accelerator pedal is completely released or free, then turn “ON” ignition switch and wait for 3 seconds. You want completely depress the accelerator pedal very hard and fully release the accelerator pedal as quickly as possible 5 times within 5 seconds.

Can a bad TPS cause transmission problems?

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.
