Common Reasons For P2262 CodesSymptoms
Turbocharger electronic actuator malfunctionThis will activate the Check Engine Light and also the ECM memory to store the error code P2262.
Problems with turbo sensors, filters,  or the hosesEngines will lack power and turbo boost when they are under load or accelerating.
Deficiencies or faults exist within the ECMThe ECM goes into failure management mode and reduces engine power.
A short or open on the turbo controller’s return wire to the ECMEngine power is reduced as the ECM switches to failure management mode.

This can cause the engine to lose power and cause internal damage if the turbo vane becomes stuck in full boost mode. Consequently, the engine may be damaged due to an over-boost condition.

Ensure the turbo is also free of other problems. If the air pressure is low, the code P2262 can occur. This is why it is so important to maintain normal airflow. If the turbocharger has any issues, it is necessary to replace its control actuator assembly or the other components.

Problems With Turbo Sensors, Filters, Or The Hoses

However, for diagnosing a P2262 code within the ECM, analyze the freeze frame data to identify the failure. You should clear all ECM memory codes before checking freeze frame data to avoid false or duplicate results.

Do the same after the fix. You may need to replace the entire ECM unit in some situations, which will be the most expensive fix for the P2262 code.

A Short Or Open On The Turbo Controller’s Return Wire To The ECM
