2003–2004 NISSAN ALTIMA AND SENTRA WITH QR25DE ENGINE; VOLUNTARY RECALL CAMPAIGN CRANK ANGLE SENSOR / ECM REPROGRAMMING

Nissan has determined that on some 2003 – 2004 Altima and Sentra vehicles with the 2.5 liter engine the operation of the crank angle sensor is significantly affected by variations in temperature that occur due to the unique location of the sensor in the engine. Under certain driving conditions, these variations in temperature can be large enough to cause a brief interruption in the signal output from the sensor. If the interruption in the signal from the sensor is so brief that the Electronic Control Module (ECM) logic does not have time to diagnose the condition, the engine may stop running without warning while the vehicle is driven at low speed.

On some model year 2002-2005 Nissan Altima and 2004-2005 Nissan Maxima vehicles, there is a possibility that corrosion of the rear sub-frame may occur. Corrosion is most likely in cold climates where heavy salting of roads is common practice in freezing conditions. A mixture of road salt and water can promote corrosion in the rear sub-frame bushings of some vehicles. In severe cases, cracking of the rear sub-frame may occur, which may result in a knocking noise coming from the rear of the vehicle. The performance or handling characteristics of the vehicle are not affected and it is safe to drive the vehicle.
