Guide To P0248 OBD Error Code Solutions

<<See All OBD Codes

The fault code P0248 is defined as Turbocharger Wastegate Solenoid B Range/Performance. This code would mean that the wastegate activity is not controlled by the solenoid in the intended manner due to a defective solenoid, wiring, or because of a stuck wastegate door.

It is always great to learn more. That’s the reason why we are here to help you out. In a turbocharged vehicle, the wastegate would divert the exhaust by opening as well as closing a certain degree at the certain times. This would help in regulating maximum boost pressure and would offer a safeguard to protect the engine as well as turbocharger itself.

This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model.

What causes this problem with the Turbocharger Wastegate Solenoid B Range/Performance?

• The wastegate solenoid might be faulty
• Defects in the solenoid wiring or connections
• An open or short in the wastegate solenoid B harness
• A wastegate door might be stuck too far open or closed
• Some malfunction in the powertrain control module

It is vital to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0248 here:

Common Symptoms

• The malfunction indicator lamp can start illuminating
• There may be rattling or whining in the turbocharger or its pipes
• The engine performance can be poor or bad
• The spark plug may be fouling
• Car engine or transmission may get too hot
• If the vehicle is equipped with a boost pressure gauge, it will show excessively high boost pressure levels

Want to correct the Trouble Code P0248? Read these points mentioned below:

• You must repair the solenoid circuitry such as wiring and connectors
• If there are some issues with the wastegate solenoid B, then it should be repaired or replaced
• The faulty powertrain control module should be replaced

Here are some steps which you should follow in order to diagnose this fault code:

• A code reader should be hooked up to check for other faults and to record freeze frame data
• If there are any DTCs then all them should be cleared, then the vehicle should be taken out for a road testing to see if they return
• Diagnose and then repair any codes which occurred along with P0248, in the order in which they occurred
• Make sure that you visually inspect the wastegate solenoid B and its wiring and connectors
• It is very important to examine the solenoid voltage and resistance against the manufacturer’s specifications
• Inspect the wastegate door to see if it’s stuck
• Make sure that you observe the wastegate door and actuator rod while activating the vacuum pump

Common Mistakes When Diagnosing The P0248 Code

The actuator rod and other involved components are easy to overlook when diagnosing this code. Simply replacing the wastegate solenoid without also making sure that the circuitry is sound and that the wastegate door isn’t stuck may result in repeated failure in the solenoid circuit

One big mistake can be failing to repair any concurrent boost pressure sensor fault codes. Make sure that you rectify before you move further to fix the wastegate solenoid circuit
