Question about Chrysler 300
I think you mean a crankshaft or camshaft position sensor.
Crankshaft position sensor can be checked with an ohmeter, check for these 3 things.
1. 5 Volt supply to terminal 1 which is looking at it from the front and the clip on top.
2. Check for earth on the middle terminal.
3. Ceck for signal from ECU or CKP which will fluctuate between .05 - 1.25 volts on terminal 3.
Crankshaft position sensor is on the left hand rear of the engine looking at it from the front.
Camshaft sensor should really be checked with a ossiclliscope but you can check the voltage and grounds etc the same as the crankshaft sensor.
This can be found at the front of the engine.
The O2 sensors there are 2 of them one on each sdie, in the exhaust system.
These have 4 terminals and when you are looking at them from end on at the connector they are numbered 1 - 4 from top left to bottom right.
1. Should be ground
2. Should be heater control to ECU
3. Return signal from ECU
4. Out put signal.
All the other O2 sensor signals are the same.
I hope this helps, let me know if you need more information
