Last updated on July 11th, 2023 at 09:18 pm

In case you are among people who ask “What happens if you disconnect the throttle position sensor’’? Then here is what to know whenever you with to your concern on, what happens whenever you disconnect your throttle position sensor is that when the throttle position sensor is not adjusted in the right way as evidenced by a 500rpm idle, and any hesitation with initial acceleration, unplugging the throttle position sensor connector should then cause a correct idle, and normal acceleration.

Note that correcting the throttle position sensor then produced a correct idle and no code.

What are the symptoms of a bad accelerator pedal sensor?

In case you are not aware, one of the effects of a bad accelerator pedal sensor is very obvious as it directly affects how your car is drive or responds to the pedal and gas mileage. So once you notice any of these symptoms occurring or your car isn’t responding very well whenever you press the gas pedal, you should pull over the car immediately and call your mechanic.

So below are some of the symptoms which you can look for if your car’s accelerator pedal sensor is failing or bad.

1. Car moving slowly when you press the gas pedal

As you know, this symptom is very easy to notice as every car owner is very familiar with how their car responds whenever they press the gas pedal. Once you notice that your car is moving slowly, it means your accelerator pedal sensor is failing. If this happens, you are advised to pull over your car immediately and call your mechanic since bad pedal timing can prove to be fatal.

2. Your car engine doesn’t idle very well

Note that the optimal RPM of any car engine is about 600 to 700 rotations per minute. When in these RPMs, the engine will idle very well without shaking and won’t consume fuel. In case you notice that your car is not able to idle very well, a bad accelerator pedal sensor could be one of the reasons and might not be the fuel mixture.

3. Vehicle not accelerating over a certain limit

In case your vehicle is accelerating up to a point and doesn’t go faster beyond a particular speed, then your accelerator pedal sensor can send positioning signals correctly which will cause your vehicle not to speed up beyond a particular point of pressing the gas pedal.

4. Vehicle won’t jerk upon depressing the pedal

In case your accelerator pedal sensor isn’t working correctly as it should, it will give out an incorrect reading to your vehicle’s computer system. If this is the case, it happens because the sensor is bad, meaning depressing it would sometimes give out delayed signals or different signals, which your vehicle computer system accumulates and uses it to adjust the mixture.

5. You’ll observe a low gas mileage

Most times your car’s throttle position sensor will be at its failing stage but the effects won’t be obvious to you. Sometimes you won’t be noticing any delayed response when pedaling but if you notice low gas mileage, it means that the vehicle’s throttle position sensor is working well but not as accurate as it should be.

Conclusion on what happens if you disconnect throttle position sensor

Remember that once you have a bad throttle position sensor, your vehicle will not perform safely and correctly. So driving with a bad throttle position sensor might cause more harm in other related systems of your car, and this will mean additional repair bills for you. So get it fixed immediately
