Nissan Sentra Engine and Engine Cooling Problems

Model years: 2002, 2005, 2006

Problem: On certain passenger vehicles equipped with a 2.5l engine, the crankshaft position sensor can overheat causing a brief interruption in the signal output from the sensor.

Risk: If the interruption in the signal from the crankshaft position 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 a low speed increasing the risk of a crash.

Fix: Dealers will reprogram the ecm free of charge. Certain my 2006 altimas which have been previously remedied under recall campaign 06v223 (nissan r0606) are not included in this recall since the reprogramming for 06v223 also included this reprogramming. The recall began on december 31, 2007. Owners may contact nissan at 1-800-647-7261.

Model years: 2003, 2004

Problem: On certain passenger vehicles equipped with a 2.5l engine, the crank angle sensor is affected by temperature variations. Under certain driving conditions, these variations in temperature can be large enough to cause a brief interruption in the signal output from the sensor.

Risk: 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 a low speed increasing the risk of a crash.

Fix: Dealers will reprogram the ecm free of charge. The recall began on august 21, 2006. Owners may contact nissan at 1-800-647-7261.

Problem: Certain passenger vehicles equipped with 2.5l engines may experience excessive engine oil consumption as a result of improper performance of the piston rings.

Risk: If the oil is not maintained at least at the minimum level, engine damage can occur and in extreme cases result in an engine fire.

Fix: Dealers will reprogram the electronic control module (ecm or engine computer). Your vehicle will also be inspected to determine if it has been consuming engine oil at a higher than normal rate. In a small percentage of vehicles, engine replacement will be needed. On june 9, 2006, nissan notified owners of the possibility of excessive oil consumption and the importance of maintaining the oil at a proper level. Follow-up letter to owners advising them of the status of the recall was sent during august 2006. Followup letter to owners was sent on november 15, 2006. Owners may contact nissan at 1-800-647-7261.

Model years: 2000, 2001, 2002, 2003

Problem: On certain electric vehicles, the front suspension transverse link's ball joint bracket may break from stress concentration at a notch created by surface roughness and the shape of the material cut-line.

Fix: Dealers will replace the bracket on these vehicles. Owner notification began december 15, 2003. Owners should contact nissan at 1-800-647-7261.

Model years: 2000, 2001, 2002, 2003

Problem: On certain passenger vehicles, the circuit board for the crank position sensor or cam position sensor may have an improper solder joint due to solder deformation caused by heat stress accelerated by the existence of flux residue during the soldering process.

Risk: This could cause the "service engine soon" warning light to come on, create a no start condition, cause reduced engine power, or cause the engine to stop running without warning during vehicle operation, which could result in a crash.

Fix: Dealers will replace the crank position sensors. Camshaft position sensor(s), and in some cases, the variable timing control sensor(s). Vehicles involved in a previous recall campaign, 01v357, are also included in this new campaign. The replacement sensors used in that campaign are also affected. Owner notification began on december 22, 2003. Owners should contact nissan at 1-800-647-7261 or infiniti at 1-800-662-6200.

Model years: 2002

Problem: On certain vehicles equipped with the 2.5 liter engine, the exhaust pipe hanger pin may catch debris from the road that could be ignited by contact with the main catalyst. Also on 2002 altima and sentra vehicles, certain engine operating conditions may cause the pre-catalyst to overheat and damage the catalyst substrate.

Risk: Either of these two conditions could result in a fire.

Fix: Dealers will remove the protruding portion of the exhaust pipe hanger pin. In addition to the corrective action, in order to reduce the risk of fire in the event of poor or improper maintenance that could result in oil spillage, heat shield(s) will be installed on the pre-catalyst and exhaust tube. Owner notification began on july 28, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact nissan at 1-800-647-7261. Nissan recall nos. R3007, r3014, r3015, r3016, r3017. Also on 2002 altima and sentra vehicles, certain engine operating conditions may cause the pre-catalyst to overheat and damage the catalyst substrate. If substrate particles enter the combustion chamber, they could score the cylinder walls, resulting in increased oil consumption. If the engine oil level is not checked on a periodic basis and drops below the low level, and the driver continues to operate the vehicle ignoring noticeable engine noise, engine damage may occur which could result in a fire. The pre-catalyst will be tested to ensure it is working properly and replaced if necessary. If damage is found inside the pre-catalyst, it will be necessary to replace the engine.

Model years: 2000, 2001

Problem: Vehicle description: passenger vehicles equipped with a 1.8 liter engine. The engine could stop running while being driven due to a defective crank position sensor. This could also result in the "service engine soon" warning light coming on or reduced engine power.

Risk: If the engine stops running while the vehicle is in motion, it could result in a crash.

Fix: Dealers will replace the crank position sensors. Owner notification began december 10, 2001. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact nissan at 1-800-647-7261.
