Hello, I have some questions regarding the sensors.

1) How many sensors do W210 have (approx.)? Please give a list of all sensors and where we can find/buy them online.

2) How do you know which one is out-of-order or not, such as the oxygen sensor, how do you know this sensor is working properly or not?

Thank you!

May I suggest you to read all the stickies first and you would have a better idea on W210 and its sensors. W210 is not just about sensors, other parts are important too. Good luck. Could you also fill up your info under the user cp link? Thank you.

True what you said, ILJ.
But just for the fun, let's see how many sensors we can list. I'll get the ball rolling:

MAF sensor - 1
Wheel sensors - 4
Camshaft position sensor (CPS) - 1
Crankshaft position sensor (KPS) - 1
O2 sensors - 4
Knock sensors - 2/bank (M112), 3/bank (M113) ???
Lateral Acceleration Sensor - 1
Steering position sensor - 1
Outside Temperature sensor - 1
Condenser temperature sensor - 1 (And probably a few more for the aircon)
Sun sensor for aircon - 1
AT speed sensors - At least 2, probably more
Rain sensor - 1 if car equipped with rain sensing wipers
Washer level sensor - 1
Cooling fluid level sensor - 1
Cooling fluid temperature sensor -1
Oil level sensor - 1
Oil pressure sensor - 1
Brake fluid level sensor - 1
Disc pad wear sensors - 2 or 4 depending on model)
Noise level sensor (Radio) - 1
Crash sensor - At least one in front, probably more.
Cabin temperature sensor - 1
Fuel level sensor - 1
Ambient light sensor for instrument panel - 1
Air pollution sensor for auto switch to charcoal filter - 1
Seat belt sensors (for front airbag deployment) - 2 (Not sure about rear belts)
Passenger seat occupancy sensor - 1
Park assist sensors (if so equipped) - 4/6 ???
Anti-tow sensor(s)/Anti theft sensors - ??

Of course, every door light, trunk light and glove box light switch can also be seen as a sensor. :D

Kobus, your list must have taken a lot of brain power to compile. I saw this thread a couple of days ago and thought bennypong made an unrealistic request. To answer his questions (how many sensors, where to buy them, and how to test them all) would take someone several days! I stopped just short of telling him where to go. ;)

I see this as an impossible task. :D

So I looked up and there are sensors after sensors. Some I have no idea what they are for. :)

Brake value sensor
Diaphragm travel sensor
Fuel rack position sensor
Interior motion sensor
Needle position sensor
Paddle value sensor
Flame sensor
Tilt sensor

Even MB has so many sensors, its sensation and response functions are still incompatible with those of human beings'. As I believe GOD created human, I believe He was and is and would be the best engineer.

I wonder if the OP hoped to buy a full set of spare sensors. I guess he'll be able to buy several cars with the price of one complete set of sensors. :eek:

insofar as jumping in with the intent of testing each one, or as OP queried,
"...How do you know which one is out-of-order or not.." am thinking that
only a small handful of diagnostic dongles and software is up to the task.
the challenge is that there is ODBII readable DTC and then there is the
interpretation needed to access and patch into the manufacturer's
enhanced interface.

so if you spent a few mins click touring the Autoenginuity site, you'll see
that their software is able to interrogate the MB brain(s) needed to
isolate....then display the enhanced/added sensors for results.

we know SDS can do this. we know Autoenginuity can display nearly all
of them. I've also see another handful of diagnostic soft/hardware which
boasts similar.

these are all going to be at least several hunderd dollars US, on up to
several thousand depending on the features desired.

right now, i'm leaning towards Autoenginuity's products but that'll end up
costing me about $500 for a glamorized OBDII, but the advantage lies in
its logging capability. i need to review things i do on my E320 to see if
I *need* to have enhanced sensor logging, or I merely enjoy enhanced
coded information.

(am on a bit of a high due to meds so I hope the above makes sense)

oxygen sensor (airmass) it controls the air coming in to the engine clenders, if its not working you will notice disturbance in the engine voice when turning it on, it seems like the engine is about to turn off (unequal voice).

If an O2 sensor goes bad, you will likely receive a fault code and a Check Engine Light.

Many of these are engine specific.

Fuel rack is om606.
Needle position is CDI engines.
