Possible Causes of P0236
A P0236 code can be triggered by faults across several systems. Identifying the exact root cause requires proper diagnostic equipment and live data — not just reading the code.
Boost Sensor Partial Failure
Sensor degraded and reading outside calibrated range.
Boost Leak
A boost pipe leak causing actual pressure to differ from expected.
Sensor Pipe Fault
Pipe connecting sensor to boost circuit is cracked or disconnected.
Turbo Fault
Actual boost production is outside the expected range.
Why we don't list the exact part: A P0236 code tells you what's happening but not why. Replacing parts based on the code alone is the most common way drivers waste money. A proper diagnosis identifies the specific cause first.

P0236 and Your MOT
A stored P0236 fault code will cause your car to fail its MOT. The engine management light will be illuminated during the test — an automatic failure under current MOT standards. Even if the light temporarily clears, the code remains in ECU memory and can be read by testers.
Get the fault diagnosed and repaired first, then have the code cleared and confirm the light stays off before booking your MOT.
