ASPIRATOR SYSTEM REMOVAL AND FUEL PRESSURE REGULATOR INSPECTION OR REPLACEMENT - EMISSIONS RECALL
CAMPAIGN
PURPOSE
Mitsubishi Motor Sales of America, Inc. (MMSA) is recalling all 1995 Eclipse vehicles equipped with the 2.0L non-turbo (420A) engine and manual
transmission for an emissions related condition.
BACKGROUND INFORMATION
Description of Condition
The NOx emission level on these vehicles may not comply with the U.S. Environmental Protection Agency (EPA) or California Air Resources Board (
CARB) emission regulations. Additionally, the fuel pressure regulator on some of these vehicles may fail.
Remedy
This Emissions Recall Campaign includes the following procedures:
^
Inspection, and replacement of the fuel pressure regulator if required.
^
Removal of the exhaust aspirator system (secondary air injection system)
^
Reprogramming (or replacement, if necessary) of the powertrain control module (PCM)*
NOTE:
A PCM reprogramming cartridge (MIT992016) will be sent to each dealership for use in completing this Emissions Recall Campaign.
Repair kits for removing the aspirator system (P/N 05013898AA), fuel pressure regulators (P/N M04883076), and PCMs (if required) are available to
perform the necessary modifications to the affected vehicles. Refer to the Parts Information section of this bulletin.
*NOTE:
Some early vehicles were built with a Powertrain Control Module (PCM) that cannot be reprogrammed and must be replaced. If the PCM requires
replacement, as determined by the service procedure, refer to the Parts Information chart to determine the appropriate replacement PCM part number.
AFFECTED VEHICLES
1995 Eclipse 2.0L Non-Turbo (420A Engine), Manual Transmission
CUSTOMER NOTIFICATION
A letter will be sent by first class mail to all registered owners of affected vehicles. The letter instructs them to return their vehicle to their Mitsubishi
dealer so the dealer can perform this campaign procedure at no charge. A copy of this customer letter is shown with this bulletin.
A. Fuel Pressure Regulator Inspection and Replacement
! WARNING
The fuel system is under constant pressure, even with the engine off. Fuel pressure MUST be released before servicing the fuel rail.
1.
Locate the fuel pressure regulator (on the passenger side end of the fuel rail). Identify the color of the casing of the regulator. If the casing is
painted black, proceed with step 2 to replace the regulator. If the casing is silver stainless steel, the regulator has already been replaced and
therefore does not require replacement. Do not replace the silver regulator. Skip to Section B and proceed with Removal of the Aspirator System.
2.
Loosen, then retighten the gas cap to release any pressure inside the fuel tank.
