INTRODUCTION

Nissan has determined that on some 2004 model year Sentra and 2004-2005 model year Altima vehicles equipped with the 2.5 liter engine there is a possibility that power valve screws located in the intake manifold may become loose. If this occurs the Malfunction Indicator Lamp (MIL) may illuminate and unstable engine idling or power loss may occur.

IDENTIFICATION NUMBER

Nissan has assigned identification number P5202 to this campaign. This number must appear on all communications and documentation of any nature dealing with this Campaign.

NUMBER OF VEHICLES POTENTIALLY AFFECTED

The number of vehicle potentially affected is approximately 81,300.

DEALER RESPONSIBILITY

It is the Nissan dealer's responsibility to check Service Comm for the campaign status on each vehicle falling within the range of this Voluntary Service Campaign (P5202) that enters the service department. This includes vehicles purchased from private parties or presented by transient (tourist) owners and vehicles in a Nissan dealer's inventory.

OVERVIEW OF REPAIR

For most vehicles, the basic repair will be to inspect the Power Valve Plates and Screws and, if all screws are installed, to replace the Power Valve screws with new ones. Depending on results of the inspection process, more extensive repairs, including repair or replacement of the engine may be required.





Use the Repair "Flow Chart" shown to determine the complete repair procedures for a specific vehicle.

SPECIAL CUSTOMER ASSISTANCE FEATURES

Customers should be informed that:

a. The basic repair for this campaign should take approximately 3 hours to complete.

b. A limited number of vehicles affected by this campaign may require more extensive campaign repairs.

c. If engine replacement is required:

^ The repair may take up to 5 days to complete.

^ Car Rental Assistance is available upon owner request and is to be provided free of charge to the customer.

Refer to the Claims Information section of this bulletin for additional information related to Car Rental Assistance.

INFORMATION REGARDING ENGINE & EXHAUST SYSTEM MODIFICATION(S)

Some vehicles may be presented for repair that have been modified using non-Nissan components or in a way not authorized by Nissan. Vehicles that have minor or cosmetic modifications (such as a modified air filter/intake system) will be eligible for this campaign, as long as the modifications do not affect the dealer's ability to diagnose and install the campaign parts in accordance with this bulletin within the allotted time(s).

Owners of vehicles with more extensive, non-Nissan approved engine and/or exhaust system modifications may be responsible for bringing the vehicle into a condition that allows the campaign procedures to be followed and the repairs completed. Extensive modifications to these systems may make diagnosis (an essential part of this campaign) and the installation of campaign parts not possible. In such cases, the engine/vehicle must be returned to an appropriate condition in order for the campaign repair to be performed.

For example, the following Original Equipment Manufacturer (OEM) parts must be installed and functional:

^ all oxygen sensors

^ the pre-catalytic converter

^ catalytic converter

^ engine (ECM) control module

Once the campaign repair is completed, the re-installation of any non-Nissan parts is the financial responsibility of the owner and the cost to install these parts must be negotiated between the dealer and the vehicle owner. The Nissan dealer may elect not to perform any repairs that may violate emissions or other regulations.

For questions regarding modified equipment, contact the Warranty Claims Call Center.
