It converts intake manifold or turbocharger boost pressure into an electrical signal the engine computer uses to calculate air density and load for fuel and timing control.
What are signs this sensor may need replacing?
A lit check engine light, rough idle, hesitation, or reduced fuel economy can point to a pressure-sensor fault. Diagnose the cause first; if the sensor is at fault, this replaces it.
