Polaris Electronic Throttle Control Problems And Solutions

Since electronic throttle control (ETC) has numerous advantages over mechanical one, it sometimes raises some common problems as well. Less power, fuel inefficiency, engine stalling, poor acceleration, faulty throttle control sensor, low fuel pressure, and so on are among the common Polaris Electronic Throttle Control Problems.

Most of the ETC problems are not that complicated and easily fixable. But you have to go through proper maintenance to keep your Polaris ETC well.

We will discuss some common Polaris ETC problems and their common solutions. Before getting to the point, the electronic throttle control system’s working principle may help you understand the issues quickly.

What Is The Principle Of Electronic Throttle Control (ETC)?

Electronic throttle control is the replacement of mechanical throttle control that throttles ups the engine by electronic signal instead of physical contact.

For more clarification, mechanical throttle works when you step into the gas pedal and the throttle opens. Then air goes to the engine, helps to burn the fuel and power up the engine.

But in ETC, it uses electronic signals instead of a physical attachment. By pushing onto the Polaris accelerator, you activate the accelerator pedal module. The pedal module passes the electronic signal to the electronic throttle control, and the throttle control then opens the throttle for performance.

The Most Common Polaris Electronic Throttle Control Problems

The following table will show you the most common problems that an electrical throttle control encounters. Have a close look to learn the most common Polaris electrical throttle control problems.

Problems	Cause
Less or uncertain power	Uncertain amount of air entering
Acceleration issue	Lack of power
Fuel inefficiency	Raise of dirt and dust
Electrical problem	Wiring issues, or connection is corroded
Stuck throttle body	Carbon build-up
Imbalanced fuel-to-air ratio	Faulty throttle control sensor
Faulty fuel injection	Clogged fuel injection pump

Here is an in-detail discussion on the various and their reasons. Have a close look to understand the issues well so they can be easy to solve.

1. Less Or Uncertain Power

One of the most common ETC problems is generating less power by the engine. It is because sometimes the throttle may face issues with proper air entering into the engine oil. As a result, the throttle malfunctioned.

In this case, the fuel itself doesn’t burn in the correct portion and can’t produce the proper power it should do. As long as this issue happens, the throttle also encounters acceleration problems. In such cases, the throttle can’t be adequately accelerated as well.

2. Fuel Inefficiency

When dirt and dust are gained inside and outside the throttle body, one of the most common problems that may arise is fuel inefficiency. It will burn more fuel but will not produce the right power.

As a result, you will get less mileage than before.

3. Electrical Problem

Since the name shows the perception, you know, electronic throttle depends on electrical power. Electrical powering up is basically powered by wiring.

So, the electrical problem is not unexpected in ETC. It can be caused for various reasons like corroded connectors, faulty wiring, loose wiring, etc.

4. Stuck Throttle Body

Sometimes, your electrical throttle control may work, but its body may get stuck. So, you may wonder why this happens. The primary reason the throttle body is stuck is due to carbon and dirt buildup.

5. Imbalance Fuel-To-Air Ratio

Another big problem is the imbalanced fuel-to-air ratio of the throttle, which makes the engine power unstable. It happens because when the electrical throttle control encounters a faulty throttle control sensor.

Aside from this, the clogged air filter also can cause an imbalanced fuel-to-air ratio. The throttle can’t balance fuel and air by properly opening itself in such a case.

6. Faulty Fuel Injection

The throttle control problem may happen due to a faulty electronic fuel injection (EFI) system. Here, the fuel injection may be restricted due to the faulty EFI pump and can’t inject the fuel into the engine efficiently.

So the reason behind the faulty EFI pump is the clogged pump that is blocked because of gaining dirt and trash.

Aside from the above-mentioned ones, there are several signs that indicate Polaris ETC issues. They are-

Your car’s engine may stall
You may experience black smoke
Limited and inconsistent speed

All problems may indicate by the check engine light ON, etc.

Note: Most of the problems happen due to dirt and dust. So, these are not that complicated in most cases to solve the throttle control problem.

How To Solve The Polaris ETC Problems?

So, as we mentioned already, most of the problems happen due to dust and dirt. So, it’s luck for you that this will not create that much hazard if you clean the dirt and grime yourself.

And yes, the primary and possible solution is cleaning the throttle body and other related components regularly.

But in case of an electrical problem due to damaged wiring, you have to replace the old wiring with a new one. In this case, we would suggest you go to a professional car mechanic shop.

On the other hand, if your Polaris electronic throttle control body is entirely damaged due to improper maintenance or has passed its lifespan, you might need to replace the electronic throttle body as well.

FAQs

Read these frequently asked questions below to have more information on this matter.

What happens if I drive with my ETC light on?

Basically, the engine light may stay ON due to the primary reasons we have described above. So, you can drive a little with the ETC light on. However, you are recommended to diagnose and fix the issue as soon as possible. Otherwise, this may drive your Polaris ATV into more trouble.

What is the minimum lifespan of a throttle body?

The electronic throttle bodies are designed to last a minimum of 150000 miles. Sometimes longer than this. But, you have to maintain proper maintenance. Otherwise, it is not wondering if you get the throttle body damaged within 100000 miles.

Final Note

Most of the Polaris Electronic Throttle Control Problems happen due to dirt and grime and are not complicated at all like other sensitive ones. So, proper maintenance could be the best prevention of such issues.

Also, you need to fix the issues as long as you notice them. Otherwise, excessive late may drive your Polaris ATVs into more trouble.
