Will a bad throttle position sensor throw a check engine light?

Will a bad throttle position sensor throw a check engine light?

The throttle position sensor (TPS) is part of your vehicle’s fuel management system, and helps ensure that the correct mixture of air and fuel is delivered to your engine. This sensor can fail gradually, or all at once. In most cases, the Check Engine Light is illuminated if a TPS failure is detected.

Can a throttle position sensor work intermittently?

Intermittent Errors A throttle position sensor must issue a steady stream of data to the computer to account for each throttle adjustment. If the throttle position sensor fails to relay a “throttle closed” signal to the computer, the car will stall or experience start-up problems.

Can a bad check engine light be a bad TPS?

The check engine light will randomly turn on and off even if the car is running smoothly without any jerks and stalling. This is often the first ever symptom of a bad TPS. Using a code reader, you should be able to confirm whether a faulty TPS is the culprit or a different component.

  5. Sudden surges in speed while driving on the highway.
  6. Intermittently flashing of check engine light for no apparent reason.
  7. Difficulties in changing gears.

What should I do if my throttle response is low?

The first place that an automotive technician will likely inspect when the throttle response is low is the fuel filter. The filter is responsible for removing debris to avoid engine issues and to improve fuel economy.
