E30-E36 Chamshaft position SENSOR problem??

[ReSuL]

dear my friends..

I thought I was having problem with my E30 chamshaft position psensor since even if I unplug it the car runs without any change and without error code in DME.. so I wanted one of my friends buy the sensor for me from germany and and I gave the part number..

the bmw dealer in germany said that the part number changed and he gave E36 m42 chamshaft position sensor instead of E30.. I learned it after chacking the part number of the recieved sensor... although the engine is same m42 the plug is different. but it is not a big issue I can shave the upper part and plug  it.. but the problem is that will it work on it??

Check both sensors resistance in manual.

anyone who tried it?? I have E30 manuel but do not have E36

[ReSuL]

anyone who tried it before??? this is urgent..

On the E36 it's 12.5 ohms approx between terminals 1 & 2 if the internet is telling the truth 0.4 ohms between terminal 2 & 3.

However, the car should start and run without the sensor working at all. What problems are you experiencing?

[ReSuL]

that is what I see in the new and also old sensor 1250.. my problem is that the car does not pull good enough.. it should accelerate much faster... I have checked lots of things and I have no error code..

Is there O ring installed on the sensor? These sensors are very sensitive if the gap is not correct.

[ReSuL]

yes there is an o ring on it..

How are you gauging it acceleration or lack of? I would suggest checking timing, and double check that you are getting good fuel flow if you feel there is a loss of power.

Firstly I compare it with with my previous m42 and then I compare with most of the cars on the road and mine shouldnt be like this.. in my previous m42 I would feel the seat on my back when I was accelarating...

I have checked lots of things including timing and fuel pressure.. the repairmen (not one repairman) said there is noproblem with those issues.. I have tried another AFM, put on new O2 sensor and lots of thing.. the last thing was chamshaft position sensor but I am not sure whether it is the same sensor since the plugs are different but the numbers on both sensors are same..

Does your car have catalytic converter? Check and clean all the connectors with contact cleaner.

[ReSuL]

yes it has.. I have changed the whole exhaust system and also put a catalytic convector.. I should try the second idea: cleanng the connectors but what do you mean by "all"? the ones about the sensors???

I mean check all. Because it could be you have some moisture/oil in connectors somewhere and it gives you not correct signals. Check wiring harness connectors (big one, near fuse box) also. Open them and spray with contact cleaner, let them dry and connect again. Use pure contact cleaner without any lubricants or other sh.... Also check for broken wiring insulation especially near connectors.

Ok I will try my best.. thank you very much..

What do your spark plugs look like? I am guessing at this point the car must be running lean, so maybe that means a failing coil driver, which means a new DME?
