Some components of a fuel injection system must be erased, but before doing so, drain the fuel system pressure. Then, the engine cover fasteners should be unscrewed and the cover should be unbolted in case it is present. For 2013 and model year before or for 2014 and model year and for Rogue Select models, the cowl panel will need to be unplugged. Remove two bolts and the air inlet duct is set away from the throttle body and air filter housing for 2014 and future model Rogue except Rogue Select. Remove the following components for the 2013 and earlier models Or 2014 and later Rogue select models Pull out the air filter housing and resonator assembly. Remove the wire connector from the black terminal of the battery. Label and remove the PCV hose, brake booster hose, TCA, EVAP hose and PCM. Take off the throttle body along with its gasket and place the two on the side but do not detach any hose connected to the coolant. As you will be removing the throttle body, go ahead and take out the intake manifold support bracket fasteners and the bracket if fitted. Bulb the fuel line from the fuel rail and ensure you that you may end up removing the fuel injectors and fuel rail to access for the mounting bolts. On the 2014 and later model year vehicles excluding Rogue Select, remove the front exhaust pipe and the electrical connectors from the intake manifold runner control valve position sensor and runner control valve. Unbolt the intake manifold's nuts and bolts in reverse while tightening sequence, take the intake manifold off the
Cylinder Head. To do on 2013 or earlier models and 2014 or later Rogue Select models, take off the manifold, then take out the intake manifold adapter. For installation, all previous gasket material and sealant should be scraped off with the help of a scraper from the manifold and cylinder head, then use the brake system cleaner to wipe the mating surfaces. If the model is prior to 2013 or 2014 and later Rogue Select models, place a new gasket on top of the adapter and align the intake manifold on the cylinder head studs. Place a new gasket on the studs and then put the intake manifold on the studs and tighten the nuts/bolts on it. Having sequentially tightened the nuts/bolts to the required torque, the last process is to re-tighten the first bolt, then check the torque again. The remain portion of the installation is done in a sequence that is opposite to the removal process. Last but not the least and that is why the battery needs to be reconnected and some of the re-learn procedures need to be done.
