four Painful Signs That Your Car'south Engine Control Module Has Problems

Your automobile'south Engine Command Module (ECM) monitors all the sensors in the vehicle to make sure that the car'south systems are running equally they're supposed to. When conditions change, the ECM volition automatically make adjustments in real-time. That is why information technology is so important to recognize the symptoms of ECM failure.

The ECM controls a number of systems, but the near important ones for our purposes are the air to fuel ratio, the engine timing. It as well controls the transmission in automatic transmission vehicles, and valve timing on vehicles with variable valve timing.

This is superior to erstwhile, mechanical systems, where you lot had to adjust the carburetor from time to time or have the engine timing tuned. However, it can also be a footling opaque if you're used to doing your own repairs.

When an effect arises, the ECM will log an error code that lets you lot know the source of the problem. This tin can be advantageous since yous can determine the verbal cause of failure. Information technology can also exist inconvenient since you'll need a mechanic with an expensive computer to read the error code.

What Would Crusade ECM Failure?

Considering ECMs are electrical systems, they're subject to brusque-circuits, power surges, and other failures that plague electronics.

The almost common source of ECM failure is in one of the wiring harnesses. If the wires to the transmission or fuel injectors become corroded, they can lose conductivity, leading to a failure. Fortunately, these issues tin usually be resolved by replacing the corroded wires.

If one of the wires shorts out to the frame, the ECM may fail entirely. This tin can besides happen due to power surges due to a lightning strike or arc welding on the vehicle frame.

Installing a new starter tin can also cause ECM failure. This is because they often featherbed the surge protector on the ECM, leading to a power surge when you start the vehicle. The same thing can happen if you get your wires crossed while jumping your motorcar.

A failing bombardment can also cause ECM failure. While most of your motorcar's systems tin run on far less than 12 volts, dead bombardment cells tin impact your ECM earlier they affect your starter or headlights. In this situation, replacing your bombardment will usually solve the problem.

4 Symptoms of ECM Failure

At that place are a few things that tin can tip y'all off that there's a problem. Hither are the four most common symptoms of a bad ECM reckoner:

The Check Engine Lite is on

There are many reasons your Check Engine light can plough on. These range from emissions bug to faulty O2 sensors to bug with the ECM. If your car seems to run fine but the Check Engine lite won't plow off, your ECM may exist at fault.

The but manner to be sure is to visit a mechanic with the proper computer. They can analyze your vehicle's fault codes, and let you know exactly what the problem is.

Your Car Fails to Showtime

If your ECM can't make adjustments to your motorcar'due south timing or air to fuel ratio, the vehicle may not start at all. Of course, at that place are other reasons a car may not commencement, including a bad starter or a blown alternator. If yous've replaced these parts and your motorcar won't offset, your ECM is the most likely cause.

Once again, you'll need to take your motorcar to a mechanic to exist certain.

Bad Performance or Fuel Economy

Since the ECM controls your air to fuel ratio and transmission, a faulty unit of measurement can cause your gas mileage to driblet through the floor. It tin too make your machine sluggish, or give y'all trouble when going up hills or suddenly accelerating.

If your vehicle used to run well but is suddenly having issues in these areas, you probably have a faulty ECM. Bank check with your mechanic to be sure, just replacing your ECM will commonly solve these problems.

Rough Shifting or Other Transmission Issues

This applies to automated transmission vehicles but. The ECM doesn't control the transmission on a stick shift, so if you're having bug with your five-speed, information technology'south the transmission.

If y'all've done numerous repairs on the transmission and replaced your automated transmission fluid and you're yet having bug, the ECM could be at the root of your problems.

Other Potential Problems

Our list wasn't exhaustive. Your ECM too has sensors on the radiator, the air filter, the vacuum pipe, the throttle body, the camshaft, and the crankshaft. At that place'southward also a knock sensor on the engine itself.

While these sensors aren't likely to cause whatsoever catastrophic problems, failures in these areas can cause your ECM to make unnecessary adjustments that bear on your automobile's performance.

In these cases, though, the problem is unremarkably with the sensors, and not with the ECM. Replacing the faulty sensors should resolve your issue.
