P006D Code - Barometric Pressure - Turbocharger/Supercharger Inlet Pressure Correlation

Quick Answer

The Engine Control Module (ECM) monitors the Barometric Pressure sensor and Turbocharger/Supercharger Inlet Pressure sensor signal. Common causes include Faulty Barometric Pressure sensor and Turbocharger/Supercharger Inlet Pressure sensor, Barometric Pressure sensor and Turbocharger/Supercharger Inlet Pressure sensor harness is open or shorted, Barometric Pressure sensor and Turbocharger/Supercharger Inlet Pressure sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P006D Description

The Engine Control Module (ECM) monitors the Barometric Pressure sensor and Turbocharger/Supercharger Inlet Pressure sensor signal. The ECM sets the OBDII code when there is a signal correlation problem between the engine computer and Barometric Pressure or Turbocharger/Supercharger Inlet Pressure sensor.

What does this mean?

What are the Possible Causes of the DTC P006D?

Faulty Barometric Pressure sensor and Turbocharger/Supercharger Inlet Pressure sensor
Barometric Pressure sensor and Turbocharger/Supercharger Inlet Pressure sensor harness is open or shorted
Barometric Pressure sensor and Turbocharger/Supercharger Inlet Pressure sensor circuit poor electrical connection

How to Fix the DTC P006D?

Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the P006D code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P006D Code

1. What does the OBDII code P006D mean?

P006D indicates a correlation issue between the barometric pressure sensor and the turbocharger/supercharger inlet pressure sensor, meaning their readings do not match as expected.

2. What are the common symptoms of P006D?

Symptoms may include reduced engine performance, poor fuel economy, difficulty starting, engine hesitation, or the check engine light being illuminated.

3. What causes the P006D code to trigger?

Common causes include a faulty barometric pressure sensor, a malfunctioning turbocharger/supercharger inlet pressure sensor, wiring or connector issues, or a problem with the engine control module (ECM).

4. Can I continue driving with the P006D code?

While the vehicle may still be drivable, it might experience reduced performance and efficiency, and ignoring the issue could lead to further engine or turbocharger damage.

5. How do I diagnose the P006D code?

Diagnosis involves using an OBDII scanner to confirm the code, inspecting sensors and wiring for damage, and comparing barometric and inlet pressure sensor readings using a multimeter or scan tool.

6. How do you fix the P006D code?

Repairs may include replacing a faulty barometric pressure sensor or turbocharger inlet pressure sensor, repairing or replacing damaged wiring or connectors, or updating/reprogramming the ECM.

7. Can a dirty air filter cause the P006D code?

While unlikely, a severely clogged air filter could restrict airflow and indirectly contribute to pressure sensor issues. It’s worth checking and replacing the air filter if necessary.

8. How much does it cost to fix the P006D code?

Repair costs vary, but replacing a sensor typically costs between $100 and $300, including parts and labor. Additional repairs, such as fixing wiring, may increase the cost.

9. Can a vacuum leak trigger the P006D code?

A vacuum leak is not a primary cause of P006D, but it can contribute to pressure discrepancies, especially if it affects the turbocharger system.

10. Does the P006D code affect emissions?

Yes, the P006D code can potentially affect emissions if it leads to improper air-fuel mixture or turbocharger performance, which could result in higher pollutant output.
