2009 Nissan Sentra Problems
The electronic throttle actuator (throttle body) can fail causing a loss of power and illumination of the Check Engine Light.
The catalytic converter closest to the cylinder head can fail causing illumination of the Check Engine Light. Prompt repair of this problem is recommended because the catalyst material can be sucked into the engine and cause internal damage.
Crankshaft and camshaft position sensors can leak oil into the connector causing Check Engine Light illumination. The engine may also stall as a result. Leaking sensors should be replaced. Certain 2000-2003 models were recalled for a separate camshaft and crankshaft sensor issue. For more information on the recall please click here»
Screws inside the intake manifold can become loose causing internal engine damage if they fall out completely. Our technicians report that using a strong thread locker on the power valve butterfly screws can help prevent them from becoming loose.
