Had a mechanic to check the engine codes, and the Cam sensor was one the issues. Do someone have a diagram of the location of the cam sensor location on a 95 s420 mercedes benz 4.2l v8 w140 engine?

Whom ever replaced the sensor, must have done so, based on the code & not on testing to find out why the code was set. Codes do not tell you what is wrong or to replace any parts. My advice would be to find a shop that is the best around at diagnosing vehicles,I wish I could give you a guide & questions to ask in your search but I can't You will have to ask other people where they go to & what type issues they had & the shops can resolve. On a vehicle 10 years old & for those who never change their oil on a new vehicle & that includes most people,you could have mechanical problems A sensor reports an out of range condition,so if you have no wiring issues or other sensors pulling that one down,mechanical issues are a good place to look The way to do that is using an oscilloscope & the proper software,& not every shop has that-- shall we say equipment, knowledge & skill level. Use your codes & Google them & your vehicle & look for known issues with whatever motor you have.
I believe this is a rebranded chevy trailblazer. I would start with an exhaust cam actuator which is located right next to the power steering pump. 90% of the time this will fix the problem. If it does not than it is possible there is an issue with the timing chain or a PCM issue.
The primary intent of this code is to detect slipped camshaft timing. Have you checked the camshaft timing? Your symptoms indicate you are a tooth off.
P0344 means that the Camshaft Position Sensor is having intermittent disruption.
Check the connector real well and the wires for breaks, cracks, bulging wires etc.
I think that aftermarket sensors are worthless to be honest. I recommend OEM sensor only because aftermarkets often don't work. So if you bought a CAM sensor at your local parts store then I would take it back and order from Chrysler.
A chipped tooth on your CAM sensor can cause this code as well because the sensor reads rotation. A missing tooth of the CAM will give an in the rotation of the CAM.
So the first this I would do is check the crankshaft position sensor as a fault from there can effect the CAM sensor too.
The crankshaft position sensor is in the engine block behind the alternator / just above the oil filter. See diagram below. Clean it real well and check the wiring.
Also make sure you clear the codes after the repair of they will remain. A CAM light does not usually just go away after fixing the reason for that code.
Now check the wiring and connector to the CAM sensor reall well and repair as necessary. Now clear the codes and see where you stand. If that light comes back and it is the same code then get an OEM CAM sensor and clear the codes again.
If that light comes back again then you will need to pull the timing cover and inspect the CAM itself for missing test.
If you have any questions please feel free to ask.
If you are satisfied with my help then please do leave a comment so others know of my quality work.
Crankshaft location diagram.
Pull the connector and the mounting bolt[s] to remove.
If you disconnect the Cam sensor with key on or engine running then you will get a Cam sensor code,If you disconnect and the vehicle runs yes you will get a Cam code (because its disconnected it will state Cam sensor high),If your vehicle has jump timing belt you will also get a MAF code. You may want to get the MAF check out,For now review your timing marks
The camshaft Position Sensor in a 2006 Kia Spectra is located in the cylinder head on the right side of the head near the front of the engine. (if you are standing at the passenger fender area, this will be on YOUR left on the side of the engine nearest the windshield.) (See Diagram)
NOTE: if you are trying to fix a cam sensor code, it should be noted that MANY cam sensor fault codes can be caused by things OTHER than a defective cam sensor. For example, loose timing belt components can cause erratic cam sensor readings and cause the computer to set a code for the cam sensor. Proper diagnosis should be performed.
P0335 and P0336 Engine crank sensor malfunction
To test this code, have a visual inspection of the location and wirings of the crank sensor. If the engine has a cam sensor, you might mistook it as the crank sensor (it is a good idea to contact ATS that can research this for you). Check the sensor wires for insulation making sure it is getting a voltage signal as shown in the wiring diagram. Sometimes, the wires itself is soaked with dirty oil causing the sensor to fail. If OK, check the engine timing belt system for any slack which can also cause the sensor to throw in the code. If all of these prove OK, remove the crank sensor and check it for resistance as compared to the standard specs. Lots of times, if the sensor probe end is contaminated with oil or cracked, this can only be revealed after the crank sensor is removed
Hi...
The Code P0340 on your Stratus is :
Camshaft Position Sensor Loss signal.
Ok, The first step is check tha condittion on the connector.
For corrosion, bent pins or damaged wires.
If you found that everything is ok.
Replace the Cam Position Sensor.
The Cam Position Sensor, Is common that the Cam fail on this Vehicle and similars of this.
Tha Cam position sensor Is located:
At end of the engine head, driver side. Is attached with 4, 10mm
screw, and the connector at the center of the sensor.
I hope this help on your problem.
Thank you for use fixya...
