INTRODUCTION

Infiniti has determined that some 2002-2003 model year Infiniti vehicles may have a defect which relates to motor vehicle safety. The engine might stop running while being driven if the crank position sensor or cam position sensor fails. This may also result in the Service Engine Soon light coming on or reduced engine power. If the engine stops running while driving this could result in a crash without warning.

IDENTIFICATION NUMBER

Nissan has assigned identification number R3021 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 vehicles potentially affected is approximately 58,000.

DEALER RESPONSIBILITY

It is the retailers responsibility to check Infiniti Net for the campaign status on each vehicle falling within the range of this voluntary safety recall which for any reason enters the service department. This includes vehicles purchased from private parties or presented by transient (tourist) owners and vehicles in a dealer's inventory.

Federal law requires that new vehicles in dealer inventory which are the subject of a safety recall must be corrected prior to sale. Failure to do so can result in civil penalties by the National Highway Traffic Safety Administration. While federal law applies only to new vehicles Infiniti strongly encourages dealers to correct any used vehicles in their inventory before they are retailed.

PARTS INFORMATION

CLAIMS INFORMATION

Submit a "Campaign" (CM) line claim using the claims coding information shown.

If identified on Service Comm with Campaign I.D.: R3021

Service Procedure
Notes

You will replace the following sensors: Crankshaft Position Sensor, Camshaft Position Sensors, and in some cases the Variable Timing Control Sensors. The service procedures are divided by engine "family" and vehicle model (see Figure C).

NOTE: Use Service Comm to confirm the vehicle is included in this campaign before performing the following procedure.

IMPORTANT ^ There are two sensor kits associated with this campaign - one kit for each engine family (see Figure A).

^ THE SENSORS IN EACH KIT ARE DIFFERENT. IT IS CRITICAL THAT EACH SENSOR BE INSTALLED IN THE CORRECT LOCATION. REFER TO FIGURE A AND THE ILLUSTRATIONS IN EACH REPAIR SECTION FOR SENSOR LOCATIONS.

^ Each new sensor (within each kit) is contained in a bag. The bag is labeled with the Nissan part number. Keep the sensor in the bag until just before it is installed. The supplier part number is molded onto the face of the sensor. This number starts with "A29-".

^ The Crankshaft and Camshaft Position Sensors in Sensor Kit P/N 23731-4M527 look the same. To help you tell the difference between these sensors, a white paint mark was added to the Crankshaft sensor (see Figure A).

^ The old and new sensors may appear identical, therefore KEEP THEM SEPARATE.

^ When disconnecting the vehicle harness connector* from the sensor(s); first PUSH the Release Button inward, then PULL the connector back (see Figure B). NOTE : Do NOT pull on the wires when disconnecting the connector.

* The button for this connector is green and the connector body color is green or black.
