The most common symptom of a failed crankshaft position sensor on a Nissan is that the car hesitates to start or stalls after it starts. Read codes from the ECU. If no broken wires were found, then the next thing you need to do is inspect all connectors attached directly to the backside of the crankshaft sensor housing, making sure none of them have become corroded over time due to wear and tear exposure to the elements. If it has learned the CASE, you're done and the reset is complete. You will arrive at a position where further rotation of the crankshaft pulley becomes difficult. After all, once the sensor scanner has been connected, starting your car is not really necessary. In other cars, the sensor could be installed at the transmission bell housing, or in the engine cylinder block, as in the photo below. If drivers don't rec-calibrate or re-engineer the engines after they have been replaced, the vehicle might start to stall. Keep the temperature of the coolant and air temperature sensors close to each other. Start the engine and make sure the engine oil and coolant are at optimal temperature. The car can confidently hit the street with an uninterrupted and smooth operation.
To precisely troubleshoot the crankshaft position sensor, you would need to crank the engine and use an oscilloscope to continuously monitor the sensor signals, where you can check for any sudden drop in the sensor signal output (ignore the signal drop corresponding to the empty slot of the reluctor wheel tooth). Disconnect the crankshaft position sensor and the electrical connector. The ECU uses that information to fire the fuel injectors and the spark plugs at the right time.
