The cheaper sensor will be fine.

Is yours definitely dead? I ask as I haven't had a failure in 27+ years. They're very reliable.

The last car I had this fault on was the engine ECU. Wouldn't start with a crankshaft signal fault. Scoped the crankshaft and confirmed it was working .

Wouldn't start with a crankshaft signal fault.

Yes, and the fault (code 17??? can't remember) is a red herring. The code always appears as the engine isn't running so the CPS can't return a signal. Apparently the code doesn't appear if the enigine's running but I've never tried.

All this on my '91 124.

True. It's because the sensor is an inductive type as only generates a voltage (sine wave) when the engine is spinning rather than a hall sensor that can be checked for open/short by the ECU.

 

[rayhennig]

checked for open/short by the ECU.

Yep. I measure mine by unplugging from the Ignition Controller (sometimes misrepresented as the EZL!). Should be between about 800-1200 Ohms, cold/hot, I think.

The OP might test his.

@DREAMER NO2

Top right connector but your EZL will be different. Anyway, it's a coaxial connection with just screen and core.
