The Nissan Sentra is a compact vehivle produced by Nissan Motors thanks to 1983.High-mileage older Nissan Sentras might experience coolant leaking into the engine, which could cause engine failure. Symptoms include loss of coolant in the radiator and a milky substance in the oil, which can be checked on the oil dip stick and inside the oil cap. This can be caused by a cracked or warped head or a blown head gasket because of overheating, according to 2carpos.com.
Low oil levels could damage the engine or sway to an engine hearth and failure. Engines should be tested by a Nissan dealer who can in some cases interchange the engine. An estimated 85,000 vehicles might be affected, according to Engine Trend.
Sensor Overheating
As many as 653,000 Nissans, including the 2002, 2005 and 2006 Sentras equipped with the 2.5-liter engine, might acquire a crankshaft position sensor prone to overheating. This causes a vocable interruption and the engine might cutoff running without warning. The sensor should be reprogrammed, according to Engine Trend and lemonauto.com.
Sensor Interrupted
The speck of a seperate sensor in the Nissan Sentra engine compartment that sends a expression to the electronic ascendancy module too might be person to engine temperature changes. The temperature might act on the sensor transmitting engine performance information to the module, resulting in the engine stopping. This affects 2004 Sentras. The sensor should be inspected and reprogrammed whether essential.
Faulty Circuit
A course board operating the Eccentric person or camshaft position sensors in 2003 Nissan Sentras might be poor by reason of of defective workmanship. This can consideration the engine warning luminosity to clarify; to light up, decrease engine force or immediate the engine to brick wall running. The Eccentric person and camshaft position sensors, and feasibly the variable timing ascendancy sensor, should be replaced. Approximately 630,000 Nissans are affected.
Catalyst Overheating
In some 2002 Nissan Sentra and Altima models powered by the 2.5-liter engine, the exhaust tube hanger pin can catch road debris and cause a fire from the main catalyst. The exhaust pipe hanger pin should be removed and replaced with a new one. A heat shield also should be installed on the catalyst and exhaust pipe.
Crank Sensor
Some 2002 Nissan Sentras equipped with the 1.8-liter engine might have a bad crank position sensor that could result in the engine losing power, stopping and having the engine light illuminate without warning. This could result in a crash. The crank position sensor should be replaced.
Cracked Head
In the ended decade, the Sentra has been powered by engines ranging from 1.3 litres to the 2.5-liter inline 4-cylinder versions. Engine problems are generally regional to defective sensors or on-board personal computer systems that hold resulted in approximately six recalls because 2001.
