Common Questions
What does P06A5 mean and how does it affect my car?
The P06A5 code indicates a problem with the engine oil pressure control circuit. It can lead to low oil pressure, which significantly affects engine lubrication and performance. If ignored, it may result in severe engine damage or failure, impacting your vehicle's reliability and safety.
What are the most common causes of P06A5 and how much does it cost to fix?
Common causes include low oil levels (40% likelihood), faulty oil pressure sensors, and issues with the oil pump. Repair costs can range from $100 for sensor replacement to $1,200 for an oil pump replacement, depending on the specific issue and labor involved.
Can I drive my car with P06A5 or should I stop immediately?
It is not advisable to drive your car with a P06A5 code active, as it indicates potential oil pressure issues. Continuing to drive can lead to significant engine damage or failure. It's best to have the vehicle inspected as soon as possible.
How can I diagnose P06A5 myself using GeekOBD APP?
To diagnose P06A5 with the GeekOBD APP, first connect the app to your vehicle's OBD2 port. Run a diagnostic scan to retrieve the P06A5 code and any other related codes. Use the freeze frame data to understand the conditions under which the code triggered, and then check the oil levels and sensor readings for any abnormalities.
What vehicles are most commonly affected by P06A5?
The P06A5 code is often seen in 2015-2019 Ford models such as the Explorer and Edge. These vehicles may have recalls or technical service bulletins (TSBs) related to oil pressure issues, so it’s essential to check for any manufacturer updates.
How can I prevent P06A5 from happening again?
To prevent the P06A5 code from recurring, ensure regular oil changes and checks to maintain optimal oil levels. Additionally, have your oil pressure system inspected during routine maintenance to catch any issues before they escalate.
What is P06A5?
The diagnostic trouble code (DTC) P06A5 is associated with the engine control module (ECM) and indicates a problem with the engine oil pressure control circuit. This code can trigger when the ECM detects an issue with the oil pressure system that may affect engine performance. It often relates to the oil pressure switch, wiring, or the oil pump itself. When this code appears, it can lead to serious engine problems if not addressed promptly. Symptoms may include an illuminated check engine light, engine noise due to inadequate lubrication, or even engine stalling. The underlying issue may stem from low oil levels, a faulty oil pump, or a malfunctioning oil pressure sensor. This code is commonly found in several Ford models, including the Explorer and Edge, particularly from 2015 to 2019. Ignoring the P06A5 code can result in significant engine damage, so addressing it as soon as possible is crucial for vehicle longevity and performance. Regular maintenance, such as oil changes and checks, can prevent this code from occurring. If you’re experiencing symptoms or see this code, it’s best to consult with a qualified technician or use reliable diagnostic tools like the GeekOBD APP to further investigate.

Symptoms
Common symptoms when P06A5 is present:
- Check engine light stays on constantly, indicating a persistent issue with the oil pressure circuit.
- Engine hesitates during acceleration, making it difficult to maintain speed and affecting overall drivability.
- Fuel economy decreased by 10-15%, leading to higher fuel costs and concern over engine efficiency.
- Unusual engine noises like knocking or ticking, which may indicate insufficient lubrication due to oil pressure issues.
- Inconsistent oil pressure readings on the dashboard gauge, suggesting a malfunctioning oil pressure sensor or circuit.
Possible Causes
Most common causes of P06A5 (ordered by frequency):
- The most common cause of P06A5 is low engine oil levels, which can occur due to leaks or inadequate maintenance, with a likelihood of about 40%. Ensure regular oil level checks and changes to avoid this problem.
- A faulty oil pressure sensor is the second most common cause, which can misreport oil pressure to the ECM, leading to false readings and triggering the code. This issue can be addressed by testing or replacing the sensor.
- Issues with the oil pump, which is responsible for circulating oil throughout the engine, can also trigger this code. If the pump is failing, it can lead to inadequate oil pressure and engine damage. Regular checks during maintenance can help prevent pump failure.
- Less common but serious is damaged wiring in the oil pressure control circuit. This can lead to intermittent issues that may be hard to diagnose but can be revealed through visual inspections.
- A rare but possible cause is an internal engine failure, such as worn bearings or damage that affects oil circulation. This may require comprehensive engine diagnostics and possibly a rebuild or replacement.
