Check Engine Light Blinking

CHECK ENGINE LIGHT

The easiest way to diagnose and fix a blinking check engine light is to use a scan tool from Innova like the Innova 5110. This easy-to-use tool plugs directly into your car, reads the vehicle diagnostic system and reports back to you with any possible issues.

Trying to diagnose a blinking check engine light manually can be costly, as well as time-consuming. Any mistakes you make doing this manually means replacing parts, trips to the mechanic and even causing further damage.

Using the Innova 5110 means you can find the reason your check engine light is blinking, all presented in plain English – leaving you with the knowledge to fix your vehicle.

FINDING OUT WHAT’S WRONG AND HOW TO FIX IT

1 – Getting your vehicle’s data
A tool is required to pull information from the vehicle so you may view it. We recommend the Innova 5110.

2 – Download Innova App
Download the Innova RepairSolutions 2 app.

While the tool is able to display some data pulled from the vehicle, the app will be able to provide more information such as the repair and costs needed for your vehicle’s repair.

The app will work with your tool, so please wait for your tool to arrive or you may visit any of our retailers to purchase it today.

3 – Get Report
Setup your account with your tool by following the instructions here.

Then create the report following the directions here.

You should receive a report that appears similar to the one below.

Viewing the repairs and costs for your vehicle

1 – Tap the Engine Element
If your check engine is on, your report should display the red Engine element on your report.
Tap this element to view the details.

2 – View your repair
Your Engine report will display.

Providing you information on the code, the fix needed, and the parts needed for repair.

Your Options

At this point, you have two options.
1. You may attempt the repair on your own now knowing the repair needed, and the needed parts for the repair.
2. You may take the vehicle to repair shop now knowing roughly the cost of repair for your issue.

Innova does not recommend ignoring a check engine light even if the vehicle drives ‘fine’ as this can create the need for very expensive repairs later, such as replacement of a catalytic converter (which can cost on average $1,500), or even the replacement of the entire engine (potentially upwards of $5,000).

Maintaining your vehicle and addressing issues like a misfire quickly maintains vehicle safety, fuel economy and longevity.

The Hidden Cost of Guessing

What does my check engine light mean?

Your dashboard light came on. You don’t know why. And the shop wants $150 just to take a look. Sound familiar?

The check engine light on your dashboard means the vehicle’s onboard diagnostic system has detected a problem.

It could be something minor, like a loose gas cap, or more serious, like an engine or emissions issue. Either way, it’s your car’s way of saying, “Something’s not right.”

Since the cause isn’t always obvious, the best way to know what’s wrong is to scan the vehicle with a diagnostic tool. That’s where we come in—let us help discover the problem so you can fix it with confidence.

Let us help discover the problem

Scenario #1

You could ignore it—

Scenario #2

You could Google it—
but your car won’t give you straight answers.

“Quality scanners and easy to use. Not your typical knickknack scanner. Shows the monitors all on one page, codes when they’re pending, stored or permanent, tells you what type of computer the car has and lastly; how long the check engine light was on. In other words, this is works well and is worth your buck.”
