BMW Crankshaft Position Sensor

[wan520i]

Dear sifus,There are 2 specs for CPS (coil resistance): 1. 540 ohms +- 10% for all models. 2. 1280 ohms +-10% for model with breakerless ignition distribution.Anybody know which model excalty #2 refer to?? what is "breakerless ignition distribution" ? fuseless? According to Bentley manual, it say #1 is specs for M20/M30, and #2 for M50/M60 engines.Anyway, mine CPS reading is M50B25tu:395 ohms. And also I managed to measure few engines: M20B20: 679 ohmsM50B20:405 ohms M52B20: 617 ohms M52B28:600 ohms Your inputs please, Thank you.

cps resistance values

per Bentley :

m20/m30........540 ohms +/- 10%
m50/m60........1280 ohms +/- 10%

replaced mine approx 3 years back.resistance value was 800 ohms ++ if memory serves me right
