What does check electronic throttle control mean?

What does check electronic throttle control mean?

These days, it’s all electronic — and that means that when something goes wrong with the throttle, you’ll see a warning light on your dash. The throttle control warning light will normally light up briefly each time you start your vehicle, and then go off.

What does the electronic throttle control system do?

Electronic throttle control facilitates the integration of features such as cruise control, traction control, stability control, and precrash systems and others that require torque management, since the throttle can be moved irrespective of the position of the driver’s accelerator pedal.

What sensor is used to determine the position of the accelerator pedal on a system that uses an electronic throttle control ETC system?

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.

How do I reset my electronic throttle control system?

Make sure that the accelerator pedal is fully released. Turn ignition switch “ON” and wait at least 2 seconds. Turn ignition switch “OFF” wait at least 10 seconds. Turn ignition switch “ON” and wait at least 2 seconds.

How much does it cost to fix a throttle control?

The average cost for throttle body replacement is between $577 and $692. Labor costs are estimated between $95 and $120 while parts are priced between $482 and $572.

What causes an electronic throttle control to go bad?

In this case, the problem may be caused by a miscommunication link from the throttle controller and the engine’s air fuel mixture which is regulated by the mass air flow sensor on many cars. In most cases, issues with the throttle controller are electric, either caused by a damaged sensor or electrical relay.

Can a bad throttle body cause no start?

When a TPS goes bad, then the car’s throttle body won’t function properly. It could either stay shut or it won’t close properly which is a severe issue. If it stays shut then your engine is not going receive air and it won’t start.

How do I know if my electronic throttle body is bad?

When a throttle body is not functioning correctly, some noticeable characteristics may be poor or very low idle. This can include stalling when coming to a stop or very low idle after starting, or even stalling if the throttle is quickly pressed (resulting in the throttle body plate opening and closing very quickly).

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

The average cost for throttle position sensor replacement is between $171 and $219. Labor costs are estimated between $59 and $74 while parts are priced between $112 and $145.

What happens when you unplug throttle position sensor?

If the TPS is not adjusted correctly as evidenced by a 500rpm idle, and hesitation with initial acceleration, unplugging the TPS connector should then cause a correct idle, and a normal acceleration. Correcting the TPS then produced a correct idle, and no code.

How long should a throttle position sensor last?

80,000 miles

How do you reset the accelerator pedal position sensor?

To recalibrate the ECM and accelerator pedal, the ignition switch must be in the ON position and then the accelerator pedal must be slowly and fully depressed from idle to full throttle. Repeat the procedure three times.

Why is my accelerator not working?

If the sensor has failed and the wrong amount of air and fuel are being delivered to the engine, the driver demands will have little control over the engine. This may come off as an unresponsive gas pedal. These are usually not serviceable, but will need to be replaced if faulty.

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.

How can you tell if a throttle position sensor is bad?

1. Carefully unplug the electrical connector from the TPS.
2. Examine the electrical connector wires and terminals for dirt, contamination and damage.
3. Now, set your DMM to a suitable setting, like 20 Volts, on the DC voltage scale.
4. Turn the ignition key to the ON position, but don’t start the engine.

What is the function of accelerator pedal position sensor?

Today’s modern cars, trucks, and SUVs are all equipped with an electronic throttle control system that contains an accelerator pedal position (APP) sensor. This sensor’s primary job is to monitor the position of the throttle pedal and send an electronic signal to open the throttle body as you depress the gas pedal.

What happens when you press accelerator pedal?

Gas Pedal. When you step on the gas pedal you initiate a process that delivers air and fuel to the engine. As the gas pedal is pressed, it turns a pivot that in turn pulls the throttle wire. Various sensors monitor this airflow and inject fuel accordingly to maintain an optimum ratio of air to fuel.

What causes a gas pedal to stick?

If your accelerator were to stick it would most likely be caused by a floor mat or other object getting jammed under the gas pedal. This could obviously be avoided by keeping your vehicle clear of clutter and making sure floor mats are properly fixed in place.

What should be the last step you take if your gas pedal sticks?

8 quick steps to take if your gas pedal sticks

1. Stay calm and try not to panic.
2. Push the brake firmly with both feet and hold it down.
3. Shift the car into neutral.
4. Steadily hold the brake and look for an escape route, like a hard shoulder on the highway.
5. Do not turn off the engine unless shifting into neutral is unsuccessful.
