ModerateP0236 — Boost Sensor Issue
Description
What P0236 Means
Code P0236 points to a problem with the boost sensor. The sensor may be sending bad readings, or there's a fault in its electrical circuit. The engine management system (DME) flags a mismatch between the boost sensor signal and expected values within the given operating range.
The boost sensor measures pressure in the intake manifold downstream of the turbocharger and sends that signal to the DME for air-fuel mixture calculation and boost control. When the signal falls outside the allowed range or becomes unstable, the DME sets P0236 and may limit turbocharger operation to protect the engine.
Symptoms
