Common Questions
What does P06CB mean and how does it affect my car?
P06CB signifies a problem with the oil pressure control circuit, which can lead to inadequate lubrication of the engine and potentially severe damage if not addressed. Immediate inspection is crucial.
What are the most common causes of P06CB and how much does it cost to fix?
Common causes include a faulty oil pressure sensor, which can cost between $100 - $300 to replace, and a failing oil pump, which may cost up to $1,200. Regular maintenance helps prevent these issues.
Can I drive my car with P06CB or should I stop immediately?
It's not advisable to drive with a P06CB code as it indicates a risk of low oil pressure, which can lead to serious engine damage. It's better to stop and diagnose the issue.
How can I diagnose P06CB myself using GeekOBD APP?
Using the GeekOBD APP, you can scan for trouble codes and check for oil pressure readings. Pay attention to any anomalies in the data to help pinpoint the issue.
What vehicles are most commonly affected by P06CB?
P06CB is frequently seen in vehicles like the 2015-2018 Chevrolet Silverado and 2016-2019 GMC Sierra, among others. Ensure your vehicle is regularly maintained to mitigate risks.
How can I prevent P06CB from happening again?
Routine oil changes and inspections of the oil system can help prevent P06CB. Always use quality oil and filters to maintain proper oil pressure.
What is P06CB?
The P06CB diagnostic trouble code (DTC) indicates a problem with the engine oil pressure control circuit, which can lead to decreased oil pressure or improper oil flow. This issue is often seen in vehicles such as the 2015-2018 Chevrolet Silverado and 2016-2019 GMC Sierra. The code means that the engine control module (ECM) has detected that the oil pressure is not within the expected range. Low oil pressure can result in severe engine damage if not addressed quickly. When the oil pressure drops too low, it can cause the oil pump to fail, leading to insufficient lubrication of engine components. This can result in increased friction, overheating, and ultimately, engine failure. Symptoms include a warning light on the dashboard, engine noises, and poor performance. It's crucial for car owners to understand that ignoring this code can lead to costly repairs down the line, so addressing P06CB promptly is essential for maintaining vehicle health.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P06CB is present:
- The check engine light illuminates, remaining on until the issue is resolved.
- You may notice a decrease in engine performance, particularly during acceleration.
- Engine oil pressure gauge may show low readings, indicating potential oil flow issues.
- Unusual engine noises, such as knocking or ticking, can occur, signaling insufficient lubrication.
- A noticeable decrease in fuel economy may be experienced due to the engine working harder.
Possible Causes
Most common causes of P06CB (ordered by frequency):
- The most common cause of P06CB is a malfunctioning oil pressure sensor, accounting for about 60% of cases. This sensor may send incorrect readings to the ECM, triggering the code.
- Another cause could be an oil pump failure, which may reduce oil pressure. This typically happens due to wear or a clogged oil filter.
- Low oil levels or dirty oil can also trigger this code, as they affect the oil's ability to circulate properly. Regular oil changes can help prevent this.
- Less common causes include wiring issues or connectors that are corroded, affecting the signal between the sensor and the ECM.
- In rare cases, internal engine problems like wear in the bearings can lead to low oil pressure, necessitating significant repairs.
P06CB Repair Costs
Cost Breakdown by Repair Type

If the oil pump is failing, it may need replacement, which can be more labor-intensive.
- Total: $500 - $1,200
- Success rate: 85%
Money-Saving Tips for P06CB
- Start with the most common and least expensive repairs first
- Use GeekOBD APP to confirm diagnosis before replacing expensive parts
- Consider preventive maintenance to avoid future occurrences
- Compare prices for OEM vs aftermarket parts based on your needs
- Address the issue promptly to prevent more expensive secondary damage
Diagnostic Steps
Professional P06CB Diagnosis Process
Follow these systematic steps to accurately diagnose P06CB. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Conduct an initial visual inspection for obvious issues such as damaged wiring or loose connections (5-10 minutes)
Step 1: Conduct an initial visual inspection for obvious issues such as damaged wiring or loose connections (5-10 minutes).
Step 2: Step 2: Use the GeekOBD APP to perform an OBD2 scan and retrieve all diagnostic trouble codes and freeze frame data (10-15 minutes)
Step 2: Use the GeekOBD APP to perform an OBD2 scan and retrieve all diagnostic trouble codes and freeze frame data (10-15 minutes).
Step 3: Step 3: Test the oil pressure sensor using a multimeter to ensure it is functioning correctly (20-30 minutes)
Step 3: Test the oil pressure sensor using a multimeter to ensure it is functioning correctly (20-30 minutes).
Step 4: Step 4: Check the oil level and condition, replacing the oil filter if necessary to ensure proper oil flow (15-20 minutes)
Step 4: Check the oil level and condition, replacing the oil filter if necessary to ensure proper oil flow (15-20 minutes).
Step 5: Step 5: After repairs, conduct a system function test to verify that the oil pressure has returned to normal levels, clearing any codes (10-15 minutes)
Step 5: After repairs, conduct a system function test to verify that the oil pressure has returned to normal levels, clearing any codes (10-15 minutes).
Important Notes
- Always verify the repair with GeekOBD APP after completing diagnostic steps
