Common Questions

What does P068D mean and how does it affect my car?

The P068D code indicates a malfunction within the powertrain control module's power supply. This can lead to starting issues, poor engine performance, and even stalling. It's crucial to address this issue promptly to maintain vehicle performance.

What are the most common causes of P068D and how much does it cost to fix?

Common causes of P068D include a faulty PCM (60% likelihood) and poor electrical connections. Repair costs can range from $100 for wiring repairs to $1,200 for PCM replacement.

Can I drive my car with P068D or should I stop immediately?

Driving with a P068D code is not recommended as it can lead to stalling or failure to start, creating unsafe driving conditions. It's best to have the vehicle diagnosed and repaired as soon as possible.

How can I diagnose P068D myself using GeekOBD APP?

Using the GeekOBD APP, you can scan for the P068D code and gather freeze frame data. Pay attention to the current engine conditions and any other codes that may appear to get a full picture of the issue.

What vehicles are most commonly affected by P068D?

Commonly affected vehicles include the 2015-2020 Ford F-150, 2016-2019 Dodge Ram 1500, and select models from Chevrolet and GMC during the same years. Check for any recalls related to the PCM.

How can I prevent P068D from happening again?

Regular vehicle maintenance, including checking electrical connections and battery health, can help prevent P068D from recurring. Consider inspections every 30,000 miles.

What is P068D?

The P068D diagnostic trouble code (DTC) indicates a problem with the powertrain control module (PCM) that manages the engine and transmission. This code specifically points to an issue with the PCM's internal power supply or its communication with other modules. When this code is triggered, it can lead to a variety of performance issues. For example, you may notice that your engine won't start, or it could run rough, impacting overall drivability. In vehicles like the 2015-2020 Ford F-150, a P068D code may cause the check engine light to illuminate, signaling a need for immediate attention. Without addressing this code, further damage could occur, potentially leading to expensive repairs and reduced vehicle reliability. It's essential to take this code seriously, as it can impact the vehicle's ability to operate efficiently and can lead to additional complications if left unchecked. As a car owner, understanding the implications of this code can help you make informed decisions about repairs and maintenance.

System: P - Powertrain (Engine, Transmission, Emissions)

Symptoms

Common symptoms when P068D is present:

  • The check engine light stays on constantly, indicating a fault with the PCM.
  • Engine hesitates during acceleration, which may lead to unsafe driving conditions.
  • Fuel economy decreased by 10-15%, resulting in higher fuel costs.
  • The vehicle may experience stalling or difficulty starting, especially in cold weather.
  • Unusual electrical issues, such as malfunctioning dashboard lights or radio problems.

Possible Causes

Most common causes of P068D (ordered by frequency):

  1. The most common cause is a faulty powertrain control module, with a 60% likelihood of being the issue. This can occur due to wear and tear or manufacturing defects.
  2. A second frequent cause involves poor electrical connections, which can lead to intermittent power supply issues to the PCM. Always check wiring and connectors.
  3. Corrosion in the connectors or wiring harness can result in significant communication problems, which can be prevented with regular inspections.
  4. Less common but serious issues include a failing vehicle battery, which can affect the power supply to the PCM.
  5. A rare cause might be a software glitch in the PCM itself, which can often be resolved through a software update from the manufacturer.
