The condition may be due to the cowl drain flowing water onto the connectors for the 02 sensor(s) at the center rear area of the engine. This leads to
water intrusion into the wiring harness connector(s) which may lead to terminal corrosion and/or MIL illumination.
DIAGNOSIS:
NOTE:
If the vehicle is equipped with a 5.7L engine (sales code EZB) and was built on or before August 18, 2004 (MDH 0818XX), perform Service
Bulletin 18-031-04 REV A as necessary before continuing with diagnosis. For 2.7L and 3.5L engines continue with the diagnosis.
1.
Open the hood
2.
Disconnect the 02 Sensor connectors and check for water intrusion and/or corrosion in both upstream 02 sensor connectors at the center rear area
of the engine.
a.
If no water or corrosion is present, reposition the wiring harness connectors to the outboard edge of the valve cover away from the center of
the engine. Tie strap the harnesses in place. If no water or corrosion was present, further diagnosis is required. This bulletin does not apply.
b.
If water is present but no corrosion, blow out the connector(s) and reposition the wiring harness to the outboard edge of the valve cover
away from the center of the engine. Tie strap the harness in place.
c.
If corrosion is present, perform the Repair Procedure.
