Can anyone tell where exactly where this sensor is, what tools are needed, and how they replaced this sensor? I already know I will have to drop my 16 valve's skid plate

I ass/u/me the front of the 190e engine is similar to my 110 engine. If so, and if you are referring not to the pin on the harmonic balance wheel, but to the electronic sensor, it can be spotted on the left side just above the harmonic balance wheel at the 2:00 position as you face the front of the car. Mine uses 1 10 mm nut to hold it in place.

That should be it. It has a wire harness that leads directly to the EZL unit and you can easily do all the work from the top side, not needing to get under the car at all. Wire routes up under several things from between the engine fan/harmonic balancer area over to the dirver's side fender apron. Easy job.

So the crank position sensor is in the front of the engine? I thought everyone here said it is above the starter near the trans??

There are two crank position sensors. One in the front called the TDC Top Dead Center sensor and there is one inthe back, I think it can be refered to as the Crank position sensor...How do you know that it needs replaced? They rarely go bad. It is usually the TDC sensor if any. The rear one would likely only be reachable from the underside.

So is the top dead center sensor the same asn the CPS? Same plug etc?

hey97 im back again....do you have the read outs for the for the rear crank sensor? I will tell you how to tech the sensor if you wish....all you need is a vom and a little patience.

a special thank you to crhenkel dude!!!!!! you located the tdc sensor for me and I thank you...I also have a 190e that will not start and guess what!!!! if found a broken wire on the sensor lets see if this is the problem....thanks for the pics

I think the spec is something like 600 ohms to 1200 ohms is acceptable. Well the sensor falls like 800 or something, well within spec. I dot know actual number but it was within factory spec

thats the spec that you need .....now check the opposite side at the ignition control unit and see what its reading ....use your vom to 20 volts scale and see what that is reading ...turn the key on to volt the system ...it should be around 11.5
one more check is to see if the insulation on the sensor is still good on the ohm scale read the middle of the sensor plug to ground .....if it stays at 1 your good...if it reads you need to replace.....make sure you check all of your electrical connections on everything
