Commonly affected vehicles include the 2015-2018 Honda Accord and the 2012-2016 Toyota Camry, among others. It's important to check for any recalls or technical service bulletins related to the power steering system.

How can I prevent P0965 from happening again?

Regular maintenance of your power steering system, including checking fluid levels and inspecting components for wear, can help prevent the occurrence of the P0965 code.

What is P0965?

The diagnostic trouble code (DTC) P0965 indicates a specific issue with the power steering pressure sensor circuit range or performance. This code is commonly triggered when the engine control module (ECM) detects that the voltage signal from the power steering pressure sensor is outside of the expected range. This sensor plays a crucial role in monitoring the pressure of the power steering fluid, helping to ensure that the steering system operates smoothly and efficiently. When this code appears, it can lead to various steering-related problems such as difficulty in steering, increased steering effort, or inconsistent steering response. In practical terms, this means that drivers may experience a heavy steering feel, especially at low speeds, which can make maneuvering in tight spots or parking very challenging. Furthermore, if this issue is not addressed promptly, it can lead to further complications, including potential damage to the power steering pump or other related components. It's important for vehicle owners, particularly those with models like the 2015-2018 Honda Accord or 2012-2016 Toyota Camry, to take this code seriously and seek a professional diagnosis and repair to maintain safe driving conditions.

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

Symptoms

Common symptoms when P0965 is present:

  • Check engine light remains illuminated, indicating an ongoing issue that needs attention.
  • Steering feels heavy or unresponsive, especially at low speeds, making it hard to maneuver the vehicle.
  • Increased steering effort, which may lead to driver fatigue during longer trips or in heavy traffic.
  • Intermittent steering feedback, where the steering response becomes unpredictable.
  • Potential noise from the power steering pump, which may indicate strain or damage.

Possible Causes

Most common causes of P0965 (ordered by frequency):

  1. Faulty power steering pressure sensor - This is the most common cause, with a likelihood of around 60%. If the sensor is malfunctioning, it can send incorrect voltage signals to the ECM.
  2. Wiring issues - Damaged or corroded wiring can lead to poor connectivity between the sensor and the ECM, which may account for about 25% of cases. Inspect the wiring thoroughly for any signs of wear.
  3. ECM malfunction - In some instances, the ECM itself may be the source of the problem, with incorrect processing of signals, although this is less common and accounts for about 10% of cases.
  4. Low power steering fluid - A low fluid level can cause erratic sensor readings, potentially leading to a P0965 code.
  5. Pump failure - In rare cases, a failing power steering pump may send inaccurate signals, triggering this code.
