Common Questions

What does P08E6 mean and how does it affect my car?

The P08E6 code indicates a problem with the power steering assist system. When this code is triggered, it can lead to increased steering effort, particularly at low speeds. This can make your vehicle harder to control, especially during tight maneuvers. It’s crucial to address this issue quickly to avoid further complications and ensure your safety on the road.

What are the most common causes of P08E6 and how much does it cost to fix?

Common causes include a faulty steering angle sensor, low power steering fluid, and electrical issues like damaged wiring. Repair costs can vary widely, from $100 for a fluid flush to upwards of $600 for a power steering pump replacement. The average cost for fixing this code typically falls between $200 and $400.

Can I drive my car with P08E6 or should I stop immediately?

While you may still drive your vehicle after a P08E6 code is triggered, it's not recommended. The heavy steering can make it difficult to control your car, especially in emergency situations. It's advisable to address the issue as soon as possible to ensure your safety.

How can I diagnose P08E6 myself using GeekOBD APP?

To diagnose P08E6 using the GeekOBD APP, start by connecting the app to your vehicle’s OBD2 port. Perform a full scan to retrieve any stored codes and review freeze frame data for additional context. Check the specific parameters related to the power steering assist system to identify the root cause of the issue.

What vehicles are most commonly affected by P08E6?

The P08E6 code is frequently seen in 2016-2020 Chevrolet Malibu and Equinox models. These vehicles have been reported to experience power steering assist issues, leading to this specific trouble code. It's advisable to check for any recalls or technical service bulletins (TSBs) related to this code for your particular make and model.

How can I prevent P08E6 from happening again?

To prevent future occurrences of the P08E6 code, regularly check your power steering fluid levels and inspect for leaks. Ensure that the steering components are in good condition and consider periodic inspections of the steering angle sensor. Keeping your vehicle maintained and addressing any steering issues promptly can help avoid this problem.

What is P08E6?

The DTC P08E6 code refers to a malfunction related to the power steering assist system in vehicles, particularly affecting models like the 2016-2020 Chevrolet Malibu and Equinox. This code typically indicates that the power steering control module is not receiving a proper signal from the steering angle sensor or there is a fault within the power steering system itself. The power steering system's primary function is to make steering easier for the driver by reducing the amount of effort needed to turn the steering wheel. When the P08E6 code is triggered, you may notice that the steering feels heavier than usual, making it more challenging to maneuver your vehicle, especially at low speeds. If ignored, it could lead to more severe issues, including complete power steering failure, which is not only inconvenient but can pose safety risks when driving. It's vital to address this code promptly, as it not only affects the drivability of your vehicle but could also lead to increased repair costs if further damage occurs.

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

Symptoms

Common symptoms when P08E6 is present:

  • Check engine light illuminates, indicating a fault in the power steering assist system.
  • Steering feels unusually heavy, especially when turning at low speeds, causing driver fatigue.
  • Inconsistent power steering assist, where the steering may suddenly become difficult or stiff.
  • Noise from the steering pump, which may be a sign of low fluid levels or a failing pump.
  • Increased effort required during parking maneuvers, making it harder to navigate tight spots.

Possible Causes

Most common causes of P08E6 (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor, which has a likelihood of around 60%. This sensor provides crucial data to the power steering control module.
  2. Another frequent culprit is low power steering fluid levels due to leaks in the system, which contributes to about 25% of cases.
  3. Wiring issues or damaged connectors between the power steering control module and the steering components can also trigger this code, representing about 10% of occurrences. Regular inspections can help prevent such wiring problems.
  4. A malfunctioning power steering pump, although less common, can also lead to the P08E6 code. It's important to keep the pump in good condition to avoid unexpected failures.
  5. Rarely, issues related to the vehicle's ECU (Engine Control Module) can result in this code if it fails to process the data correctly.
