Symptoms of a bad PCV valve on a 2006 Nissan Xterra 4.0 can include rough idling, increased oil consumption, and excessive engine noise. You might also notice a decrease in fuel efficiency and oil leaks due to increased pressure in the crankcase. Additionally, the check engine light may illuminate if the engine management system detects issues related to the PCV system.
To reset the service oil light on a 2009 Nissan Xterra, turn the ignition key to the "ON" position without starting the engine. Press the gas pedal three times within five seconds. Then, turn the ignition off and start the engine to ensure the oil light has reset. If the light remains on, repeat the process.
