A PO236 code in a Cummins diesel engine indicates a problem with the turbocharger boost sensor circuit, specifically related to the boost pressure being out of range. This could be caused by issues such as a faulty boost pressure sensor, wiring problems, or a malfunctioning turbocharger. Additionally, it may arise from vacuum leaks or issues with the engine's air intake system. Proper diagnostics and inspection are needed to identify the exact cause and address it effectively.
