ISSUE
Some 1993-98 Villagers may exhibit a Malfunction Indicator Lamp (MIL) on and Diagnostic Trouble Code (DTC) 32 on 1993-95 models, or DTC P0400 (MIL DTC 0302) on 1996-98 models indicating an Exhaust Gas Recirculation (EGR) flow malfunction. This may be caused by a cracked/leaking hose on the bottom of the EGR Back Pressure Transducer (BPT).
ACTION
Check the hose for potential cracks/leaks and, if found, replace the hose with a revised hose. The revised hose transmits an accurate exhaust back pressure signal to the BPT. It has a new shape and is made of a new material for improved durability to reduce the possibility of cracking. Refer to the following Service Procedure for details.
SERVICE PROCEDURE
1. Closely inspect the exhaust back pressure hose at the bottom of the EGR BPT for evidence of possible deterioration/leakage (Figure 1).
2. If the hose is cracked or brittle, replace it with a revised Hose (F6XZ-9F459-BA).
NOTE
1993-95 MODEL VILLAGERS REQUIRE A VEHICLE SPEED SENSOR (VSS) INPUT TO THE POWERTRAIN CONTROL MODULE (PCM) OF 8 KM/H (5 MPH) OR GREATER TO TURN OFF THE EGR CONTROL (EGRC) SOLENOID ALLOWING THE EGR VALVE TO OPERATE. WHEN TESTING THE EGR SYSTEM FOR PROPER OPERATION IN THE SHOP, GENERATE A VSS SIGNAL BY LIFTING THE FRONT WHEELS OFF THE GROUND, SUPPORT THE VEHICLE AND RUN IN DRIVE. DO NOT EXCEED 56 KM!H (35 MPH) WHILE THE FRONT WHEELS ARE RAISED.
