How to Reset Electronic Throttle Control Manually Chrysler 300

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

In this article, we are going to look at causes of a Chrysler 300 throttle control warning light and how to reset electronic throttle control manually Chrysler 300. so whether you have a Chrysler 300 red lightning bolt warning light comes on then, this post will help you identify any Chrysler 300 throttle body problems so you can know the right action to take and subsequently resetting the light.

If your car is having an engine problem, sometimes it can be difficult to identify where the problem is coming from.

Various components, which include the throttle system are working together to provide your engine with a stress-free acceleration.

So if you are concerned with any throttle problem, or you are experiencing acceleration and idling problem, today, you will know how to reset electronic throttle control manually Chrysler 300.

So what does it mean when the electronic throttle control light comes on?

Except your car is a 1990 model or older, yours likely have an electronic throttle control (ETC).

A lot of current car models have lots of computer-controlled electronic systems, ETC happens to be one of them.

This means that in current car models, there is no coupling between the gas pedal and the throttle.

But the electronic throttle control acts as the connection between these components. This simply tells you that the electronic throttle control light comes on if only there’s an issue with the system.

Whenever the throttle pedal is depressed, the electronic throttle control will receive an electrical signal and then sends the commanding actions to control the throttle’s opening and closing.

And whenever this cycle disrupts for any reason, the electronic throttle control light will be illuminated on the dashboard.

What causes an: electronic throttle control problem Chrysler 300

Different problems will lead to an electronic control problem Chrysler 300. However, one of the simplest way to know what part that is giving issues is to read the diagnostic trouble code. The code readers are what will tell you the reason the code appeared.

A faulty Throttle Control Sensor

Indeed, modern cars are full of sensors at every twist and turn. Although this allows various kinds of cool features, but the disadvantage is that when one sensor goes wrong, the entire throttle system goes down.

And that’s the problem with the throttle control sensor, which is known as the throttle body position sensor.

What this sensor does is to inform the ECU of the throttle body’s current position, so that the ECU will know the perfect fuel and timing ratios to adjust everything else too.

This means that once the throttle position sensor is faulty, the ECU will not know how to time everything, and then an engine code will illuminate.

A faulty Accelerator Pedal Position Sensor or Module

Just like the throttle position sensor, the electronic throttle control contains an accelerator pedal position sensor and also an accelerator pedal module.

What the acceleration pedal position sensor does is to send the current position of the accelerator pedal to the control module.

While the module makes use of this info in communicating with the throttle position sensor to determine the correct throttle position.

So once any of these components wear out and break down, then you will end up with a trouble code on the dashboard, and the system won’t work perfectly.

A stuck Throttle Body

Note that all the electronic components in the car can be working independently exactly the way they should, but once the actual throttle body is stuck or completely damaged, the system as a whole won’t work perfectly.

If this happens, a visual and mechanical examination will help you in knowing if the throttle body is working the way it should.

So what you should do is to open and close the throttle body and ensure to check for any visual obstructions.

Note that the throttle body should open easily and should close automatically as soon as it is released.

Where is Chrysler 300 throttle position sensor location, in a car

As you already know, the Throttle Position Sensor (TPS) is a potentiometer which reports how far open the car throttle is, to the computer.

The job is to convert electrical resistance to a voltage that the car computer interprets whenever it is setting ignition timing, fuel mixture, and idle speed.

The throttle Position Sensor is located or can be found on the end of the throttle arm which is opposite where the throttle cable hooks up and contains 3 wires (5V, signal, and ground).

Chrysler 300 electronic throttle control warning light reset

The Chrysler 300 electronic throttle control warning light reset is something you can do for yourself without taking it to any mechanic. In case you want to reset it yourself, below are the steps you need to take and these steps could also be applied for Chrysler 300 red lightning warning light reset too.

1) First thing to do is to insert your ignition key and turn to “ON” without starting.

2) Then wait for all the lights to go off. The Check Engine Light may remain on.

3) Now slowly depress your accelerator pedal to the floor.

4) Then slowly release the accelerator pedal back up again.

5) Now turn your ignition key to “OFF”.

6) Then start your car engine.

A lot of drivers observes an immediate change in their throttle response, but this depends on your driving style, sometimes you may need to repeat these steps periodically because of the computer’s adaptive programming. Also, you might need to repeat these steps any time the battery is disconnected.

How to reset electronic throttle control manually Chrysler 300

Having a rough idle can sometimes be caused by having a change in the throttle body position sensor.

So to correct any accidental changes in your throttle body or reset electronic throttle control manually Chrysler 300, you can use these processes to get it solved.

Please note that these procedures are a little tricky to do. So you must get the timing right, you can make use of a stopwatch to help the precision of your timing.

The Accelerator Pedal Release Position Learning Procedure

Ensure that your accelerator pedal is fully released

Then turn the ignition switch to “ON” and then wait for at least 2 seconds

Now turn the ignition switch to “OFF” and wait for at least 10 seconds

You can now turn the ignition switch to “ON” again and wait for at least 2 seconds

Then turn the ignition switch to “OFF” again and then wait for at least 10 seconds

The Throttle Valve Closed Position Learning

1. Just ensure that the accelerator pedal is fully released

2. Then turn the ignition switch to “ON”

3. And then turn the ignition switch to “OFF’ and then wait for at least 10 seconds

The Idle Air Volume Learning (Throttle Position Learning)

Please note that it’s best to time with a watch/clock.

1. Now Perform Accelerator Pedal Released Position Learning.

2. Also Perform the Throttle Valve Closed Position Learning.

3. Then start the engine and warm it up to normal operating temperature.

4. Now turn the ignition switch to “OFF” and then wait for at least 10 seconds.

5. Please confirm that the accelerator pedal is fully released, now turn the ignition switch to “ON” and wait for 3 seconds.

6. Then repeat the following (steps 7a, 7b) process very quickly five times within 5 seconds.

7a. Just depress the accelerator pedal (HARD) fully 7b. Release the accelerator pedal fully.

8. You can now wait for about 7 seconds and then you depress the accelerator pedal fully, keeping it for about 20 seconds until the Check Engine Light (CEL) stops blinking and turned ON.

9. Now fully release the accelerator pedal within 3 seconds after the Check Engine Light is ON.

10. Now you can start the engine and let it idle.

11. Then wait for 20 seconds.

12. Now rev up your engine two or three times and ensure the idle speed and ignition timing are within the specifications.
