Common Questions

What does P0695 mean and how does it affect my car?

The P0695 code signifies an issue with the ECM power relay circuit. When this code appears, it means that your engine control module may not be receiving the power it needs. This can lead to performance issues like stalling, misfiring, and poor fuel efficiency. If left unaddressed, it could cause further damage to your ECM and lead to more expensive repairs down the line.

What are the most common causes of P0695 and how much does it cost to fix?

The most frequent cause of the P0695 code is a faulty ECM power relay, which can typically be replaced for between $100 and $250. Other causes include damaged wiring or connectors, which can lead to repair costs ranging from $150 to $400, depending on the extent of the damage.

Can I drive my car with P0695 or should I stop immediately?

While some drivers may be able to continue driving, it's not advisable. The P0695 code indicates a serious issue with your vehicle's power supply to the ECM, which can result in engine failure while driving. It's best to have your vehicle inspected as soon as possible to avoid potential safety hazards.

How can I diagnose P0695 myself using GeekOBD APP?

Using the GeekOBD APP, connect to your vehicle's OBD2 port to retrieve the P0695 code and any additional codes that may be present. The app will provide you with freeze frame data, giving you context for when the code was triggered. From there, you can check the ECM power relay and associated wiring for any visual signs of damage or wear.

What vehicles are most commonly affected by P0695?

The P0695 code is commonly found in vehicles like the 2006-2011 Chevrolet Impala, 2010-2015 Ford Fusion, and various models from Chrysler and Dodge, particularly those manufactured between 2006 and 2018. If you're experiencing symptoms, it's worth checking if your vehicle is on this list.

How can I prevent P0695 from happening again?

To prevent the P0695 code from recurring, conduct regular maintenance on your vehicle's electrical system, including checking connections and wiring for corrosion. It's also advisable to replace your vehicle's relay components according to the manufacturer's recommended schedule.

What is P0695?

The P0695 diagnostic trouble code (DTC) indicates a problem with the Engine Control Module (ECM) power relay circuit. This code typically arises when the engine control module detects a malfunction in the circuit that supplies power to it. The ECM is crucial for managing various engine functions, including fuel injection, ignition timing, and emissions control. When this circuit is compromised, the ECM may not receive the necessary power to operate effectively. This can lead to a range of performance issues, including stalling, poor fuel economy, and even failure to start. Commonly affected vehicles include the 2006-2011 Chevrolet Impala and the 2010-2015 Ford Fusion. Drivers may notice symptoms like a persistent check engine light, engine misfiring, or decreased acceleration. Ignoring this code can lead to further damage to the ECM, resulting in more extensive repairs and higher costs down the line. Therefore, addressing the P0695 code promptly is essential for maintaining your vehicle's performance and reliability.

Symptoms

Common symptoms when P0695 is present:

  • Check engine light remains illuminated, indicating a potential issue that needs immediate attention.
  • Engine may hesitate or misfire, particularly during acceleration, causing a rough driving experience.
  • Fuel economy may drop significantly, with reports of a 10-20% decrease in miles per gallon.
  • Difficulty starting the engine, which could result from a lack of power to the ECM.
  • Electrical components may exhibit erratic behavior, including dashboard lights flickering or other electronics malfunctioning.

Possible Causes

Most common causes of P0695 (ordered by frequency):

  1. The most common cause of P0695 is a faulty ECM power relay, which occurs in about 60% of cases. This can prevent the ECM from receiving the power it needs to operate correctly.
  2. Another possible cause is damaged wiring or connectors associated with the power relay circuit, which can lead to intermittent power loss and electrical issues.
  3. Corrosion at the ECM connectors or within the relay itself can also lead to poor connections, resulting in the P0695 code. Regular maintenance and inspections can help prevent this.
  4. Less common but serious is a failing ECM, which may manifest as multiple fault codes appearing simultaneously and could require costly replacement.
  5. In rare cases, an issue with the vehicle's battery or charging system may lead to inadequate power supply, triggering the P0695 code.
