What is P06AE?

The P06AE diagnostic trouble code (DTC) indicates an issue with the engine control module (ECM) performance, specifically related to the control of the engine oil pressure control valve. This code is often seen in vehicles equipped with advanced engine management systems, such as the 2015-2018 Honda Accord and the 2016-2019 Chevrolet Malibu. When the ECM detects that the oil pressure is not within the expected range, it triggers the P06AE code. This situation could arise due to various reasons, including a malfunctioning oil pressure sensor, issues with the engine oil itself, or even problems with the ECM programming. If this code appears, it can lead to serious engine problems, as proper oil pressure is crucial for lubrication and cooling. Ignoring the P06AE code may result in poor engine performance, increased wear and tear, and even catastrophic engine failure in extreme cases. Therefore, understanding and addressing this code promptly is essential for maintaining your vehicle's overall health and performance.

Symptoms

Common symptoms when P06AE is present:

  • The check engine light activates and remains illuminated, indicating a potential problem that requires attention.
  • You may experience engine hesitations or stalling during acceleration, making it difficult to drive smoothly.
  • Fuel economy can decrease by 10-15% due to inefficient engine operation, leading to higher fuel costs.
  • Unusual engine noises may occur, such as knocking or ticking sounds, which can signify oil circulation issues.
  • In some cases, you might notice an increase in engine temperature due to inadequate lubrication.

Possible Causes

Most common causes of P06AE (ordered by frequency):

  1. The most common cause of P06AE is a faulty oil pressure sensor, with a likelihood of about 60%. This sensor may give inaccurate readings, leading the ECM to trigger the code.
  2. Another cause could be low oil levels or the use of incorrect oil types, leading to improper lubrication and pressure issues. Regular oil checks and changes can help prevent this.
  3. An incorrectly programmed ECM can also trigger this code, although this is less common. Reprogramming or updating the ECM might be necessary.
  4. Severe blockage in the oil passages can lead to oil pressure issues, a less common but serious cause that typically requires a more involved repair.
  5. In rare cases, internal engine wear, such as worn bearings, can cause low oil pressure, potentially leading to serious engine damage.
