Description Icon Long Description

Fault code P0607 is logged when an issue has been detected with the engine control module (ECM). This happens when it is determined that the ECM is unable to properly function.

This can cause a host of issues with the operation of the vehicle as the ECM controls a huge array of functions within.

The various control modules in a vehicle are onboard computers that take in information from various inputs from components around the vehicle, process the data, and then use it to optimize a number of important functions.

All modern vehicles have a control module, so this fault code is possible in any type of car.

However, Ford, Mercedes-Benz, and Toyota are some of the most commonly searched along with this fault code.

Warnings Icon Other Signs of This Problem

There will usually be some noticeable symptoms for a malfunctioning ECM.

The first and most obvious will be the presence of the Check Engine light on the dashboard.

The vehicle will also likely run poorly. This can be things like issues when trying to start the car despite it cranking, as well as unexpected stalling when driving.

It is also likely that it will run rough.

Fuel economy will also typically be reduced as the ECM cannot optimize the performance of the engine.

It is very likely that there will be another similar fault code logged that can tell more about the problem at hand. These are typically P0602, P0603, P0604, P0605, and P0606.

Broken Down Icon What Could Be The Problem?

Fault code P0607 is typically the result of a software issue, but there can occasionally be other causes outside of the control module itself.

A defective battery is one of these external causes. Insufficient power to the control module from the battery can cause this code to be logged without any actual issue within the ECM.

Similarly, a failing alternator can lead to insufficient power from the battery.

Other faults can be within the electronics of the ECM itself. Damaged or improperly fitted wiring can also cause this.

Another likely cause is that the EPCM is running on outdated software and needs an update to resume proper function.

In rare cases, the ECM itself can be faulty or defective.

Fixed Icon Fixes

Fixes for this issue can be both software related or within the ECM circuitry. Solving issues with the control modules can also require intensive programming so it is often best left to professionals.

The battery should be checked for a proper charge. If it is faulty, it needs to be replaced. If there are battery issues, the alternator should be checked and replaced if necessary.

In some cases, it is possible to leave the battery unplugged overnight to try hard resetting the control module and fixing the issue.

Software updates for the ECM should be installed.

The circuits for the ECM need to be checked for damage or loose connections in the wiring harness.

If the ECM is faulty, it needs to be replaced.

Danger Icon Seriousness

Fault code P0607 should be considered a serious issue. The ECM is a vital component in the proper operation of any vehicle. Faults in these systems can cause major issues with driveability.

It is a good idea to have this problem fixed immediately.
