There are two crankshaft position sensors on this engine: one at the front of the engine by the crank pulley, and the other at the flywheel area. One sensor detects the 1 degree signal of the sensor, and the other the 120 degree “top dead center”position.
Where is the crankshaft position sensor located on a Nissan Maxima?
It is located underneath the car, on the bottom of the engine connected to a wire with a 10mm screw holding it in. Disconnect the wire an remove the 10mm screw. That’s the input speed sensor you disconnected, the crankshaft sensor is located under the engine with a wire harness connected to it.

How do you test a Nissan crankshaft position sensor?
Touch one of your meter probes to either one of the sensor wires and the other to the other wire. Check your meter display and compare your reading to your manual specifications. In most cases, you’ll see a fluctuating signal between 0.3 volts and 1 volt. If there’s no signal, you have a bad sensor.
