Where is the crankshaft sensor located on the Nissan Teana?

Nissan Teana's camshaft position sensor is installed at the junction between the engine and transmission, mounted on the transmission housing. The function of the camshaft position sensor is to collect the position signal of the valve camshaft and input it to the ECU, enabling the ECU to identify the top dead center of cylinder 1 compression for sequential fuel injection control, ignition timing control, and knock control. The methods for measuring the condition of the camshaft position sensor are as follows: 1. The camshaft sensor is generally a three-wire Hall sensor, with one 12V or 5V power line, one signal line, and one ground line; 2. Unplug the connector, turn the key to the second position, and use a voltmeter to confirm that the power line has voltage output. Use the meter to identify the ground line by connecting one probe to the confirmed power line and the other probe to the remaining two lines; the line showing voltage is the ground line, and the remaining one is the signal line; 3. Now turn off the ignition, extend the signal line, reconnect the connector, start the engine, and measure between the signal line and ground line to check for signal voltage. The output voltage should be less than the supply voltage. If no signal voltage is detected, the sensor is faulty.
I recently helped a friend deal with a crankshaft sensor issue on a Nissan Teana and found it located at the bottom of the engine bay, right opposite the crankshaft pulley. To be more specific, it's near the engine timing cover, typically in the front section of the engine. You can vaguely spot it from above or the lower side after opening the hood. Finding it requires some patience, as it's tucked behind some components and often covered in grime. The location is crucial because the sensor detects the crankshaft's rotation angle and speed—if it fails, the car may struggle to start or trigger a warning light. During inspection, I usually use a diagnostic tool to read trouble codes and confirm the issue, then carefully remove the old part. When replacing the sensor, make sure to securely reconnect the wiring harness. For safety, ensure the engine is cool before working and wear gloves to avoid burns. Regular maintenance, like cleaning the area, can reduce signal interference caused by blockages. In short, it's near the crankshaft, and once located, replacement isn't overly complicated.
