New to the forums ...great to find such a place loaded with sooo much info...

Better half talked me into buying her a 2000 E320...since I'm an old retired tech..

I try to do all my servicing myself on all our stuff...boat ,cars,rv,and toys...I have

developed a prob with her ride...it failed to start one day...later when I got there

it started...evidently cooling off...I couldn't find anything...so I told her to drive it

till it does it again...I check coil resistance, fuel pressure....thinking it's a spark contol

module...or something similar that a MB has...still no luck...finally it set a code..check engine

light on...After some searching on the forums here I found that my problem may be a

crankshaft position sensor...I figure it is obd 2...and I need some guidance from peeps more

in tune with this ride....couple of quick questions...1- does this sound like the possible problem

since when it cools it fires again and will run for a while????...2- anything else with these

symptoms that a mb tech has encountered that they can offer up????...3- anyway to MANUALLY

pull and read codes on this ride w/o a diagnostic tool???....sorry bout the "book" but I'm just

trying to cover all bases...any and all responses are appreciated...and I also have the "NO MAG

NAG"....been reading about the fiber optics...help an old man out...lol

RE: helpin hand...
 

obd2 have no home made tool to extract the fault codes.

crankshaft position sensor is a common problem. resistance change with temperature.

was it between 800-1200 ohm?

I'm with Sleepwalker response.

In addition get the codes read. Apparently many places will do it for free in the states. A code reader isn't very expensive and very useful.
However the Crank Position Sensor doesn't usually set codes.

Thanks for the replies men...I appreciate the read...since I did

get a reply...how bout another question...a/c related..any pressure

switch I can jump to kick the compressor on???...I have mitchell on demand

and manuals from 62 to 04......so I can go thru all of mitchell's test..and

waste a day but just thought I would ask...after reading the threads on the

on board diagnostics and cleaning the heater control....I'll post my findings

on the values tomorrow...thanks again for the read...

OK here's the values for the a/c self diagnotic test...

Sensor 1 - Inside Temperature:*...84

Sensor 2 - Outside Temperature:*...85

Sensor 3 - Left Heater Core Temperature:*...87

Sensor 4 - Right Heater Core Temperature:*...84

Sensor 5 - Evaporator Temperature:*...82

Sensor 6 - Engine Coolant Temperature:*...177

Sensor 7 - Refrigerant Pressure:*...06

Sensor 8 - Refrigerant Temperature:*...85

As far as Error Codes:
E

Error B1232 - Refrigerant Pressure Sensor Malfunction

Error B1234 - Sun Sensor Malfunction

Error B1235 - Emissions Sensor Malfunction

Error B1424 - ??????

Then E...............FF...then

back to E...then repeat codes...

on the display on left..looks like a 6 instead of a b..I.E......left....Eb1........232....right

any and all help will be appreciated...thanks in advance
