Engine Fault Code P0607

Control Module Performance

Care Engine Code Reader
Engine Fault Code P0607 refers to a problem with the control module`s performance. This code is a generic OBD-II code, which means it can apply to various makes and models, including European cars like Porsche, Mini, Mercedes, Audi, Jaguar, and Land Rover.

General Meaning:
– P0607 indicates that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected a performance issue. This could mean that the module is not functioning correctly, possibly due to software issues, hardware failures, or communication problems.

Possible Causes:
1. Faulty ECM/PCM: The control module itself may be defective.
2. Wiring Issues: Damaged or corroded wiring can affect communication.
3. Poor Connections: Loose or faulty connectors can lead to performance problems.
4. Software Glitches: Sometimes, a software update is needed to fix bugs.
5. Sensor Failures: Related sensors may also be malfunctioning.

Manufacturer-Specific Meanings:
While the core meaning of P0607 remains largely the same, different manufacturers may have specific interpretations or additional codes related to it. Here are some examples:

Porsche: May indicate a specific issue with the DME (Digital Motor Electronics) control unit.
Mini: Could relate to the engine management system`s performance, possibly affecting turbocharging or fuel delivery.
Mercedes: Might involve issues with the ECU`s communication with other modules, especially in complex systems like those found in luxury vehicles.
Audi: Could indicate issues with the adaptive cruise control or advanced driver-assistance systems, depending on the model.
Jaguar: May relate to the performance of the engine control systems, especially in models with advanced electronics.
Land Rover: Could indicate a fault in the Terrain Response system or other off-road capabilities, depending on the model.

Recommended Actions:
1. Scan for Codes: Use an OBD-II scanner to check for additional codes that may provide more context.
2. Inspect Wiring and Connections: Look for any visible damage or corrosion.
3. Update Software: If applicable, check for any updates from the manufacturer.
4. Professional Diagnosis: If you`re unsure, it may be best to consult a professional mechanic, especially for complex systems.

Always refer to the vehicle`s service manual for specific troubleshooting steps and procedures.
The Engine Fault Code P0607 indicates a problem with the control module`s performance. This code can appear in various European car brands, including Porsche, Mini, Mercedes, Audi, Jaguar, and Land Rover. Here are some common causes and manufacturer-specific differences:

Common Causes:
1. Faulty Engine Control Module (ECM): The most straightforward reason is a malfunctioning ECM itself.
2. Wiring Issues: Damaged or corroded wiring or connectors related to the ECM can lead to this code.
3. Software Issues: Sometimes, outdated or corrupt software in the ECM can cause performance problems.
4. Power Supply Problems: Insufficient voltage or grounding issues can affect ECM performance.
5. Sensor Failures: Faulty sensors that feed data to the ECM can lead to performance issues.
6. Interference from Other Modules: Problems in other control modules can affect how the ECM operates.

Manufacturer-Specific Differences:
Porsche: In some Porsches, this code can be triggered by issues with the vehicle`s immobilizer system, which can affect the ECM`s ability to communicate properly.

Mini: Mini vehicles may report this code due to issues with the CAN bus communication, which is essential for the ECM to receive and send information correctly.

Mercedes: In Mercedes vehicles, this code can sometimes point to issues with the transmission control module, as it interacts closely with the ECM.

Audi: For Audis, a common issue leading to P0607 is related to the throttle body or other engine management sensors that affect performance.

Jaguar: In Jaguars, this code can be linked to problems with the adaptive learning capabilities of the ECM, which may require a software update or reset.

Land Rover: In Land Rovers, this issue might be associated with air suspension or terrain response systems that can interfere with the ECM`s performance.


If you see the P0607 code, it`s essential to perform a thorough diagnosis. Start by checking the wiring and connectors, followed by a software update if needed. If the problem persists, you may need to consider replacing the ECM or addressing any specific issues related to your vehicle`s brand. Always consult a professional mechanic if you`re unsure about any steps.
The Engine Fault Code P0607 indicates a problem with the control module`s performance. This code can apply to various vehicles, including those from Porsche, Mini, Mercedes, Audi, Jaguar, and Land Rover. Heres how to approach fixing this issue, keeping in mind that steps may vary by manufacturer.

General Steps to Fix P0607:

1. Check for Other Codes:
– Use an OBD-II scanner to check for any other fault codes. Sometimes, P0607 appears alongside other codes that can help identify the problem.

2. Inspect Wiring and Connectors:
– Look for damaged wiring or loose connections related to the engine control module (ECM). Make sure all connectors are secure and free from corrosion.

3. Reset the Code:
– Clear the fault code using your scanner. After clearing, take the car for a test drive to see if the code returns.

4. Battery Voltage Check:
– Ensure the battery voltage is within the proper range (usually 12.4 to 12.6 volts). A weak battery can cause performance issues in the control module.

5. Update or Reflash the ECM:
– Some manufacturers offer software updates for the ECM. Check with a dealership or a qualified mechanic to see if your vehicle needs a reflash.

6. Inspect Ground Connections:
– Check the ground connections for the ECM. Poor grounding can lead to performance issues.

7. Check for Short Circuits:
– Use a multimeter to test for short circuits in the wiring harness that connects to the ECM.

8. Replace the ECM:
– If all else fails and the code persists, the ECM itself may be faulty and may need to be replaced. This is often a last resort.

Manufacturer-Specific Considerations:

Porsche:
– Ensure that the vehicle`s software is up to date. Porsche models may require specialized tools for ECM reprogramming.

Mini:
– Mini models often have specific quirks; check for known issues with the ECM for your model year.

Mercedes:
– Mercedes vehicles may require a diagnostic scan with their proprietary system (Xentry) to accurately assess the ECM`s performance.

Audi:
– Audi models may also have specific updates available. Look for TSBs (Technical Service Bulletins) related to the ECM.

Jaguar:
– Jaguar vehicles might have unique wiring layouts. Be sure to consult the wiring diagram for your specific model.

Land Rover:
– Similar to Jaguar, Land Rover models can have specific issues. Check for software updates or recalls related to the ECM.

Final Note:
Always consult your vehicles service manual for specific instructions and specifications. If youre not comfortable performing these checks, its best to take your car to a qualified mechanic.
Driving with a P0607 code, which indicates a control module performance issue, can be risky. This code means that the engine control module (ECM) is not performing as it should. Heres a breakdown of what you should consider for different manufacturers:

General Considerations:
1. Reduced Performance: You might notice your car running poorly, which can lead to decreased fuel efficiency and power.
2. Check Engine Light: The check engine light will likely be on, indicating that theres a problem that needs attention.
3. Potential for Further Damage: Ignoring this code could lead to more serious issues down the line, potentially causing damage to other components.
