Pressure Feedback Exhaust Sensor: Testing and Inspection
The technician should be aware that diagnosis and testing of the EGR differential pressure feedback sensor should begin at the Powertrain Management
level, where testing begins with "general" symptom diagnosis, and is narrowed to testing of a "specific" subsystem and it's related wiring and
components. Following the appropriate diagnostic routines may prevent misdiagnosis and unnecessary component replacement. Refer to Powertrain
Management/Testing and Inspection/Procedures.
