ISSUE:
The pressure feedback electronic (PFE) EGR transducer sensor changes an exhaust pressure signal into analog voltage. The EEC IV
processor uses this to control EGR flow. Condensation (water) is a natural by-product of combustion and may collect in the PFE sensor port
or the PFE sensor silicon hose. Water in the PFE sensor port or PFE hose does not indicate an abnormal operating condition or failed sensor.
The water in the PFE sensor port or PFE hose will drain back into the EGR tube because of the downward slope of the hose. Refer to the
application chart of this TSB article for the affected vehicles.
FIGURE 6
ACTION:
Before replacing a PFE sensor for water in the sensor port or silicon tube, perform an EEC IV self test. If no service codes are found
indicating a faulty PFE sensor, do not replace the sensor, Figure 6.
