Turbo/Supercharger Boost System Performance
Related Trouble Codes:
The P2263 diagnostic trouble code indicates that there is a performance issue with the turbo/supercharger boost system.
The turbo/supercharger uses exhaust pressure and an air/fuel mixture to create boost. Vehicle manufacturers predetermine the range in which exhaust pressure is expected to stay. When/if the exhaust pressure falls below or exceeds that predetermined range, the powertrain control module (PCM) will store the P2263 diagnostic trouble code and the Check Engine Light will come on.
Uses an OBD-II scanner to collect all diagnostic trouble codes that have been stored by the PCM
Checks for damage or loose connections in the turbocharger/supercharger boost system hoses
Checks for leaks in the turbocharger/supercharger boost system oil supply line
Manually open and close the wastegate in order to make sure it is working properly
Check the boost sensor, injection pressure control, and exhaust pressure sensor to make sure they are working properly
The turbocharger will need to be removed in order to properly inspect it. Remove it and look for oil on the turbocharger. If oil is visible on the turbocharger, the turbo bearing is faulty.
Check the turbo shaft for end play. If the turbo shaft is worn out or if it is too loose, the turbocharger will need to be replaced.
Inspect the turbocharger, on the side where the exhaust is located, for any obstructions that are causing the vanes to malfunction. If obstructions are visible, the turbocharger will need to be cleaned or replaced.
Before replacing the turbocharger, it should be taken off and inspected for leaks and possible clogs. If the turbocharger is not taken off to be inspected, this can lead to a misdiagnoses. Other mistakes that are common are:
Neglecting to inspect the vacuum lines for leaks, breaks, or loose connections before replacing the turbocharger
Neglecting to inspect oil supply lines for leaks, breaks, or loose connections before replacing the turbocharger
While the P2263 diagnostic trouble code is stored, the vehicle may stall and shut off during operation. The vehicle may also be difficult to drive. For these reasons, this diagnostic trouble code is considered serious. Operation of the vehicle should be severely limited and should be diagnosed and repaired as soon as possible.
The P2263 diagnostic trouble code is most likely due to failure of the turbocharger. However, it is good practice to thoroughly inspect all other components of the turbocharger system as well. Although failure of the turbocharger is common, failure of any of these components may also cause the P2263 diagnostic trouble code to be stored by the PCM.
