P0607 is the standard OBD-II trouble code for an issue with the engine control module (ECM). The code suggests that the ECM is experiencing problems, such as power failure or memory loss, and thus may not be able to do its job properly.
The control module performance trouble code can have multiple causes:
The P0607 trouble code will usually be accompanied by the Check Engine Soon Warning Light. The vehicle may also have a problem starting, or may fail to start at all (though the engine will likely crank). If the vehicle does start, you may experience some engine issues, and the vehicle may even stall while you are driving. Fuel economy and smoothness of driving will likely be negatively impacted as well.
The P0607 code will first be diagnosed with an OBD-II trouble code scanner. A qualified mechanic will look at the freeze frame data to try and determine any related issues or clues for the P0607 code. The trouble codes will then be reset, and the car restarted, to see if the codes remain. If the P0607 code does not resurface, the ECM may be in working order, though the mechanic should still check the electrical system to make sure everything is in working order.
If the P0607 code returns following the trouble code reset, the technician will first check the electrical system. If the battery or the alternator are not providing proper electrical power to the ECM, the ECM will malfunction and the P0607 code may be triggered. If the battery and alternator are in working order, the mechanic will check the ECM itself to see if there is water damage, corrosion, poor connections, or an improperly routed wire harness.
If a mechanic cannot find any issues, then the ECM should have the software updated.
The most frequent mistake that is made when diagnosing the P0607 code is not following the correct trouble code diagnostic protocol. If a technician skips steps, they may misdiagnose the code. It’s important for a mechanic to inspect the electrical system before the ECM, as issues to the electrical system will be a quicker and smoother repair.
The P0607 code can vary in severity. Sometimes the code coming on is a fluke, and there is no actual problem with the ECM or the vehicle. At its worst, however, the P0607 code means that the ECM is malfunctioning or the battery is dying. Since the ECM is responsible for keeping your vehicle’s transmission and engine running properly, the P0607 code may mean that your car cannot be driven.
The common fixes for the P0607 code depend on the issue. Some of the potential fixes include:
If your battery has recently been changed, the ECM may have lost power and need to be reprogrammed.
