How to Fix Starting Disabled Due to Electronic Throttle Control: Ultimate Guide with Expert Tips

Often, I visit discussions regarding automobile troubleshooting on different blogs and forums. A few days back, a topic caught my attention: how to fix starting disabled due to electronic throttle control. People in that community were very cooperative. So, I thought to read and learn how to solve the starting issue. I am writing about this now!

The Electronic Throttle Control, or ETC, is like the manager of your car’s engine. It helps the engine run smoothly and muscularly. But sometimes, it can give you a warning saying, “Starting Disabled Due to Electronic Throttle Control.” It’s not as scary as it sounds, I promise!

Typically, the issue happens due to several reasons. They may include problems with the throttle body, TPS, wiring, or the ETC module. To eliminate the pain, I suggest you check these components of your car. Sometimes, you just need to ‘wake up’ the ETC by resetting it. But remember, your car is unique so that it may need a little help from a professional too!

A Brief to Electronic Throttle Control (ETC)

Do you want to troubleshoot starting disabled due to ETC effectively? Then, why not learn about it? Don’t tear your hair, as I am explaining now.

In old cars, a cable connected the gas pedal to the engine. When you press the pedal, the cable pulls. Then, the engine gets more fuel. Simple, right?

But with ETC, things got a futuristic upgrade! It uses super-smart sensors and a computer to control the engine. In this system, the sensors send signals to the computer while pressing the pedal about the quantity of air and fuel the engine needs.

An ETC system comprises several components like an accelerator pedal, throttle body, ETC module, and other sensors. It offers smoother acceleration, better fuel efficiency, and reduced emissions.

However, some issues may cause the starting disabled problem caused by ETC. These can be sensor malfunctions, electrical issues, throttle body blockages, and software glitches.

Causes of Starting Disabled Due to Electronic Throttle Control

There are indeed some causes forstarting disabled issues with electronic throttle control. I suggest you read this part, too (Sources: 1, 2)

Wiring or Connector Issues

Problems with the wiring or connectors related to the ETC system can disrupt communication between components. It can restrict the system’s proper operation and trigger the starting disabled issue.

Sensor Failures: TPS&APP

In our cars, TPS (Throttle Position Sensor) measures the position of the throttle plate. It also monitors pedal input. On the other hand, APP (Accelerator Pedal Position Sensor) detects how much you press the gas pedal. It relays that information to the ETC module.

Sometimes these sensors fail to deliver the proper signal. As a result, you can get starting disabled problems.

Potential Issues with the ETC or Powertrain Control Module (PCM)

I have already discussed ETC module. Then what about PCM? Well, it manages the vehicle’s engine functions. But it may experience issues like software glitches or electrical problems. Sadly, these problems can cause the starting disabled issue.

Mechanical issues

Mechanical problems in the engine, like issues with the butterfly valve or other parts, can affect the ETC system. They can make you worried about engine starting issues.

Diagnosing Starting Disabled Due to ETC

Dear readers, you may find diagnosing the problem slightly puzzling. Still, I am with you to help with this!

Check for Error Codes

A 2007 Grand Prix owner reported the starting disabled problem. He got a reply like this:“ You need to have it scanned by a diagnostic tool capable of reading… (PontiacForum).” So, I am saying that you should use a diagnostic tool or OBD-II scanner.

These tools can retrieve any error codes stored in the vehicle’s onboard computer system. Hence, these codes provide valuable info about the specific issue causing the starting disabled problem.

Interpret Error Codes

Have you got the error codes? Check the car’s service manual (or online resources) to understand their meanings. These error codes may indicate problems with the ETC system, TPS, or other parts.

Inspect Throttle Position Sensor (TPS)

“The TPS in your car helps ensure the proper working of the throttle valve (repairsmith).” It calculates the position of the throttle plate. However, again take a multimeter or a diagnostic tool to analyze the TPS readings. Then, compare the readings to the manufacturer’s specs to identify whether it works fine.

Check Wiring and Connections

It’s time to inspect the wiring and connections of the ETC system. You should look for loose connections, damaged wires, or corrosion in the system. If they have issues, your car will stall when you start the engine.

Check Throttle Body

It will get blockages when you do not maintain the throttle body regularly. Soon, the malfunction of this component will invite a starting disabled issue. Look for any signs of damage, wear, or blockages caused by dirt buildups. These clogged passages may hinder proper throttle operation.

Steps to Fix ‘Starting Disabled Due to Electronic Throttle Control’

Once you diagnose the starting disabled problem, you can begin to troubleshoot it. Please, spend some more time reading the below instructions:

Check ETC Fuse& Sensor

Start by checking the fuse of the ETC. Replace it if you find it blown one. Well, a blown fuse refers to an ETC without getting the necessary power. When it happens, you will get a “Starting Disabled” message.

The ETC sensor must be acceptable to function correctly. If it’s damaged, it could cause the ETC to misbehave. Thus, I suggest you carefully inspect the sensor and the wiring for any damage or wear signs.

Clean the ETC

Sometimes a dirty ETC can cause issues with your vehicle’s performance. With the passage of the time, grime and dust can build up on the ETC, causing it to malfunction. In this case, you can clean the throttle body to resolve issues related to the system.

Reset the Electronic Throttle Control System

Have you thought about resetting the ETC system? It can eliminate temporary glitches and restore proper functioning. Thus, there will be no starting disabled problem and a save of time and money.

According to Auto Accessories Review, you can reset the ETC in this ways:

First, release the accelerator pedal fully. Then, the gas pedal will be at a new, closed position. Then, turn the ignition on and off sequentially. Now, you can turn it on without igniting the engine (2 seconds). Then, turn the ignition off for ten more seconds. Follow these steps once again.

Now, turn the ignition on and wait for 6-7 seconds. Next, press the gas pedal five times and release it after 5 seconds. Wait for 6-7 seconds and press the gas pedal for 18-20 seconds. You need to do it till you see the engine light stays on consistently.

Release the pedal after 3-4 seconds when the light remains on. Then, start the vehicle engine and keep it in idle mode. After 20-22 seconds, you can rev the machine several times. It will let you know the idle speed.

Another way to perform a hard reset starts by disconnecting the vehicle’s battery for a few minutes. It will drain any residual power and reset the ETC system. Then, reconnect the battery to solve everything.

Replacing the ETC

If you cannot solve the problem till now, you may need to replace the electronic throttle control system. Usually, this step requires some help from a professional mechanic.

Frequently Asked Questions

What causes ETC system failure?

It may happen for a few reasons. Sometimes, faulty sensors like TPS and APP malfunctions cause the issue. Some other reasons can be damaged wiring, harness messing with communication between sensors and the ECM.

What happens when the ETC goes bad?

When the ETC goes bad, it can be a bit of a downer for your car. An error message like “Starting Disabled Due to Electronic Throttle Control” will appear. And then, your car will refuse to start or hesitate when accelerating.

Can you repair the electronic throttle body?

You can repair and bring back the electronic throttle body to life. Often, good cleaning or recalibration can solve the problems. But you can call the pros to sort it out quickly.
