Can a bad crankshaft sensor cause a cylinder to misfire?
Should you feel or hear a brief stutter in the engine, it may be a sign of misfiring cylinders from a bad crankshaft position sensor. A failing crankshaft position sensor cannot provide the right information about piston positioning in the engine, causing a cylinder to misfire.
How to test a crankshaft position sensor using a multimeter?
Set your digital voltmeter to a low range on the AC voltage scale. Connect your meter leads to the sensor pins. Make sure to keep your meter lead wires away from engine moving parts during this test. Have an assistant crank the engine for a few seconds while you watch the meter’s readout. The sensor should produce a voltage pulsing signal.
Where is the crankshaft sensor located on a Nissan Altima?
