In older vehicles, all of the functions were controlled mechanically. From the functions of the engine like timing and the mixture richness to simple things like the locks on the doors, mechanical systems were in place to offer the driver control over the functions of the vehicle.

These days, nearly every aspect of an automobile is controlled by the vehicle computer. This electronic control unit is really an interconnected series of computers and control units that collect data and report back to the main ECU for analysis.

The ECU can control such things as airbags, locks and electric windows, the seat position, and other matters of convenience as well as major functions such as antilock brakes, the transmission systems, and the engine itself. Because the ECU is so critical to the operation of the vehicle, a failure can result in a car that will simply refuse to start. Once you bought that car or truck, you committed to an asset that will probably endure for years to come; back up your choice by buying first-rate replacement parts. Often the trickiest part about maintaining that car is the need to find an honest source for reliable parts.

Electronic Control Unit Information

The A1 Cardone electronic control unit operates either a single system or several systems in your vehicle.




The A1 Cardone electronic control unit is the brains of the vehicle. This part is crucial for the operation of modern vehicles.

This is so you can be sure that you are getting a control unit that is compatible with your engine's systems. Look for this part here at PartsGeek.com along with anything else you may need for your vehicle.



The Standard electronic control unit is often called the ECU.




The Standard electronic control unit is often called an ECU for short. This electronic control unit is responsible for many tasks on your vehicle. It may be used to operate a single component like the antilock brakes or it could control multiple systems. This part is so critical that your car cannot run without it. To find a new ECU, start your search here at PartsGeek.com. Input your vehicle's year, make, and model to find a unit that is compatible with what you drive.


Electronic Control Unit

Gone are the days when cars were driven by just steel, gas, gears and sheer manual effort; today's vehicles are increasingly reliant on electronic systems and sophisticated software to manage onboard operations. When your ECU starts you give out, your car's performance and reliability are sure to suffer. Left unchecked, a faulty electronic control unit could eventually leave you entirely unable to start the engine.

On PartsGeek.com you will find top quality ECUs from Bosch, Programa, Audi and Mercedes, all at exceptional prices.

We take pride in our online shop's extensive parts selection, great customer service and quick delivery times. Additionally, our 30-day return policy helps us to make sure that you get exactly the part you need to get your ride up and running again.

What is an electronic control unit (ECU)?

While original automobiles had to rely on purely mechanical systems for most accessory functions, modern cars come equipped with a wide range of electronic capabilities. From door locks and windows to the transmission itself, an onboard computer helps to guide, regulate and access these various systems remotely. This central digital hub is known as the electronic control unit, or ECU for short.

How much does an ECU cost?

Because electronic control units are powerful computerized tools, they usually require a considerable investment. Most of the ECUs on PartsGeek.com fall within the range of about $200 at the lower end and over $1000 for high end onboard computers.

Price will be at least partially dependant on the make, model and year of your vehicle. Sometimes remanufactured parts can be a bit more affordable than a new one.

What types of functions is the electronic control unit responsible for?

The ECU contains a set of pre-programmed and sometimes programmable computer chips use to operate and control engine function. This device takes in data input from various vehicle sensors. This can include a huge range of items, including seat position, antilock braking mechanisms, camshaft and crankshaft sensors as well as various automatic timing systems.

What can go wrong with an ECU? What are the symptoms?

Of course, the check engine light may be your very first indicator that something is wrong with the electronic control system. Other symptoms may include misfiring, noticeable performance or efficiency issues and even the complete inability to get the engine started.

If your check engine light does tip you off to a problem, you may be able to scan your car's onboard computer for relevant error codes. Unfortunately, this indicator can mean a lot of different things, so you may have to look elsewhere for clues.

Stalling and misfiring of the engine is another possible sign of ECU failure, particularly when the symptoms are frequent but erratic. You may also notice that fuel efficiency, acceleration and power are noticeably worse.

The part was great but the speedy service was impressive

1997 Dodge Ram 1500 Electronic Control Unit

Very Satisfied
Reviewer: Lummy

My 2005 Ford Escape had the dreaded PCM failure prevalent in the 05 & 06 models. The dealer wanted to hose me for the repair at a cost of $2300. Being somewhat mechanically inclined, I opted to source the parts and do it myself. I had an important business trip coming up in a few days and needed the part fast. Found Parts Geek online. The PCM was easy to find, easy to order and priced well below the nearest competitor. The best part was that I had my part in just a few days and installed in time for my trip. The right parts, the best price and in time. Thanks Parts Geek!
