Neglecting to inspect oil supply lines for leaks, breaks, or loose connections before replacing the turbocharger Neglecting to inspect the vacuum lines for leaks, breaks, or loose connections before replacing the turbocharger If the turbocharger is not taken off to be inspected, this can lead to a misdiagnoses. If obstructions are visible, the turbocharger will need to be cleaned or replaced.Ĭommon mistakes when diagnosing the P2263 codeīefore replacing the turbocharger, it should be taken off and inspected for leaks and possible clogs.

Manually open and close the wastegate in order to make sure it is working properlyĬheck the boost sensor, injection pressure control, and exhaust pressure sensor to make sure they are working properly Uses an OBD-II scanner to collect all diagnostic trouble codes that have been stored by the PCMĬhecks for damage or loose connections in the turbocharger/supercharger boost system hosesĬhecks for leaks in the turbocharger/supercharger boost system oil supply line How does a mechanic diagnose the P2263 code? The vehicle may stall and shut off during operation.Strange noises coming from the turbocharger.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.
