Overview

Boost-pressure sensor is evaluated through its operating principle, supply, ground, signal, physical target and controller interpretation.

The test method must match the sensor technology. Power and ground are load-tested, while analogue, frequency or digital signals are compared with scan-tool live data.

Cleaning and installation procedures are sensor-specific; aggressive solvents, physical contact with sensing elements and unverified adjustments are avoided.

Electrical checks

Verify pin functions from a wiring diagram.
Load-test supply and ground.
Compare the physical signal with live data.

Installation and validation

Repeat the original operating condition after repair.
