Pressure Feedback Exhaust Sensor: Service and Repair
REMOVAL AND INSTALLATION
1. Disconnect battery ground cable.
NOTE: When battery voltage is removed from the Powertrain Control Module (PCM), all learned values will be cleared and reset to
predetermined values. When battery voltage is restored to the PCM, the vehicle may exhibit certain driveability concerns. It will be necessary to
drive the vehicle to allow the PCM to relearn values for optimum driveability and performance.
2. Disconnect electrical connector from EGR backpressure transducer.
3. Disconnect hoses from EGR valve to exhaust manifold tube.
4. Remove EGR transducer bolts and EGR transducer.
5. To install, reverse the removal procedure. Tighten EGR transducer bolts to 3.5-4.5 Nm (31-39 lb in).
