No part of this publication may be reproduced, stored in a retreival system, or transmitted, in any form or by any means, electronic, mechanical, photocopying, or otherwise, without written permission of DaimlerChrysler Corporation. SUBJECT: EGR System Elimination OVERVIEW: This bulletin provides technical details about the elimination of EGR valves. MODELS: 2002 (RS) Town & Country/Caravan/Voyager NOTE: THIS BULLETIN APPLIES TO VEHICLE WITH A 3.3L OR 3.8L ENGINE (SALES CODES EGA, EGH, EGM). DISCUSSION: A running change to eliminate the EGR system is being made during the 2002 model year. The change will be made in steps. First, the EGR will be turned off in the calibration (PCM software), followed by the removal of the EGR valve. This left a period of time during which vehicles were built with a non-functioning EGR valve on the engine. The following information will help to identify and service a functioning versus non-functioning EGR valve: • Vehicles with functioning EGR valves. Vehicles built before September 18, 2001 (MDH 0918XX) at the Windsor Assembly Plant (”R” in the 11th position of the VIN) and September 14 (MDH 0914XX) at the St. Louis Assembly Plant (“B” in the 11th position of the VIN) will have functioning EGR valves. Normal diagnostic and service procedures apply. • Vehicles built with non–functioning EGR valves. Vehicles built after the dates mentioned above through approximately the end of October, 2001 will have a non-functioning EGR valve on the engine and may or may not have an EGR vacuum harness. Vehicles built after approximately the end of October, 2001 will not have an EGR valve on the engine. In either case, the vehicle VECI label will identify the EGR valve “non-functional” and have a dotted line to the EGR valve. For non-functional EGR equipped vehicles electronic diagnostics will not function, however, the electrical connection must be maintained if the vehicle has an EGR vacuum harness (the EGR solenoid must be energized to shut off vacuum flow to the EGR valve). If the vehicle does not have an EGR vacuum harness the electrical connector may or may not be disconnected and taped back to the harness. If a non-functional EGR valve is diagnosed with a problem, the EGR valve must be removed and cover plates installed, per the following procedure: 18-026-01 -2- PARTS REQUIRED: Qty. Part No. Description 1 04591227 Plate, EGR Cover, Head 1 05277723 Gasket, EGR Cover, Head 2 06503692 Screw Cover Plate, Head 1 04861623AA Plate, EGR Cover, Intake Manifold 1 03580172 Plug, EGR Vacuum Intake Manifold REPAIR PROCEDURE: NOTE: THIS PROCEDURE APPLIES TO VEHICLES BUILT AFTER SEPTEMBER 18, 2001 (MDH 0918XX) AT THE WINDSOR ASSEMBLY PLANT (“R” IN THE 11TH POSITION OF THE VIN) AND SEPTEMBER 14 (MDH 0914XX) AT THE ST. LOUIS ASSEMBLY PLANT (“B” IN THE 11TH POSITION OF THE VIN) WITH NON-FUNCTIONING EGR VALVES AND AN EGR VALVE PROBLEM . 1. Remove the two screws holding the EGR tube to the upper intake manifold, and save for reuse (the silicone sealing ring will remain on the intake manifold). 2. Disconnect EGR vacuum connector from nipple on upper intake manifold (if present). 3. Remove the entire EGR valve assembly with adaptor base from the cylinder head including EGR tube. 4. Install EGR cover plate, p/n 04861623AA, onto upper intake manifold using the two screws saved in Step 1. Ensure that the words “THIS SIDE UP” are visible on the cover plate after installation. Tighten screws to 4 Nm (35 in. lbs.). 5. Install EGR cover plate onto the cylinder head, using gasket, p/n 05277723, and screws, p/n 06503692. Tighten to 28 Nm (250 in. lbs.). 6. Install cap, p/n 03580172, onto EGR vacuum nipple on upper intake manifold. 7. If the EGR electrical connector is not already taped back to the wire harness tape it to the harness. POLICY: Reimbursable within the provisions of the warranty. TIME ALLOWANCE: Labor Operation No: Description Amount 25-01-45-97 EGR Valve, Remove and Cap 0.3 Hrs. FAILURE CODE: AM Authorized Modification |
hi i recently swapped engines over bought a 2001 engine and fitted it to a 2002 , the 2001 engine had a egr valve and mine didnt the garage changed the manafold over so my current car was a straight fit ,but since the change at 3250rpm it dies then re picks up after about 2 seconds is this due to the erg vavle

'02 t&c
Having the same problem as OP. My '02 T&C has no EGR valve and is throwing a p0400 code. Has hesitation / misfires while driving. There's no place on the cylinder head where one ever was, but there is a port with a cover installed on the intake manifold. What should I be checking?

Mostly after over hauling and most probably after fitting it again. Sometimes it just do misfire.
