My car experienced a few random cut-offs due to P1361: Top Dead Center Sensor 1 Intermittent Interruption. The first instance happened during a warm day when I turned the AC for the first time in over a year. Did not think much of it, to be honest, I suspected that the car overheated even though the temperature gauge pointed below 90C. Since that moment it keeps happening randomly. I purchased a new TDC sensor but before engaging in stripping off the engine cover I want to check if there is any other method to verify the fault. Some publications show how to verify the TDC sensor using DMM. Usually, it consists of two stages:

1. TDC port verification to confirm that supply voltage and GND are ok.
2. Sensor verification by measuring the impedance.

Would tapping to signal pin be a good idea to verify that the hall-effect sensor produces the signal when the engine is running?
Lastly, assuming that I am able to verify the sensor without taking the engine cover and the sensor is ok. Could Intermittent camshaft position error indicate stretched timing belt?
