Automotive diagnostic fault codes provide valuable insight into potential issues with vehicle systems. This article will explore the P1247 and P1248 error codes, their causes, symptoms, affected vehicles, and solutions. Additionally, we’ll show you how to use the CR MAX and CR Eagle diagnostic tools from www.icarsoft-us.com to effectively identify and clear these codes.

1. Meaning of the P1247 and P1248 Codes

The P1247 code refers to "Turbocharger Boost Pressure Low," while P1248 indicates "Turbocharger Boost Pressure Not Detected." Both error codes point to problems in the turbocharger system responsible for maintaining proper engine performance. These codes are part of the OBD2 system, which monitors vehicle emissions and performance.

2. Possible Causes

Turbocharger-related issues can stem from a variety of sources. Some potential causes for the P1247 and P1248 codes include:

Clogged or damaged turbocharger air intake or exhaust systems.
Leaks in the intake manifold or turbocharger hoses.
Faulty boost pressure sensor or wastegate actuator.
Damaged or malfunctioning Electronic Control Module (ECM).
Mechanical failure of the turbocharger, such as a stuck turbine or damaged blades.

3. Common Symptoms

When the P1247 or P1248 code is triggered, you may notice the following symptoms:

Reduced engine power and sluggish acceleration.
Check engine light illuminated on the dashboard.
Increased exhaust smoke, particularly under load.
Hissing or whistling sounds from the turbocharger area.

4. Affected Vehicle Models

The P1247 and P1248 codes can occur in vehicles equipped with a turbocharged engine, regardless of manufacturer. Commonly affected vehicles include diesel and gasoline turbocharged models from manufacturers like Ford, Volkswagen, BMW, and Mercedes-Benz.

5. Severity of P1247 and P1248 Codes

These codes should not be ignored. While the vehicle may still operate, continued driving can lead to more severe engine damage, reduced fuel efficiency, and increased emissions.

6. Is It Safe to Drive?

It is not advisable to drive for extended periods with a P1247 or P1248 code. Reduced turbocharger efficiency affects engine performance and can increase the risk of further damage.

7. Diagnosing with CR MAX or CR Eagle

The CR MAX and CR Eagle from www.icarsoft-us.com are powerful diagnostic tools capable of identifying and resolving the P1247 and P1248 codes. Here's how to use them:

Connect the diagnostic tool to the vehicle's OBD2 port.
Open the software interface and select your vehicle's make and model.
Use the "Read Fault Codes" function to identify error codes.
Analyze live data streams, such as boost pressure and sensor readings, to pinpoint the problem.
After repairs, use the "Clear Fault Codes" function to reset the system.

8. Solutions

Addressing these codes typically involves:

Inspecting and repairing leaks in the intake or exhaust systems.
Replacing faulty sensors, such as the boost pressure sensor.
Cleaning or replacing the turbocharger if it is clogged or damaged.
Reprogramming or updating the ECM software if necessary.

9. Repair Costs

Repair costs vary depending on the root cause. In the United States, resolving P1247 or P1248 codes may cost between $150 and $1,200. Sensor replacements are typically less expensive, while turbocharger repairs or replacements can be more costly.
