Good morning dear forum community, after which I had rest for a long time, my Omega smiled at me again friendly with the engine control light (MKL). After switching he did not immediately take gas, so, my suspicion, camshaft sensor (NWS). OP-COM on it, error, camswelenne sensor not in the target range. So the cross test so extensively and often described by Kurt. Crankshaft sensor (KWS) pulled off, it does not start. So NWS defect. So I ordered a new one. built-in, same error exists. (MKL on) Cable trajectory checked (yes, he has the famous patching point, unfortunately due to the cable length not so easy to change anymore) and found this in the wire harness, where it goes into the plastic cover in front of the timing belt, 2 cables are scrubbed through (both red/green). So wire harness patched, error still present. Old NWS built-in, MKL remains out, apparently everything good. However, during the cross test he did not jump on the NWS anyway. He jumps on KWS without any problems, but also the MKL stays out. All in all he runs round, immediately takes on gas etc. Now I stand here and doubt myself. There are the different variants with impulse encoder and reverberator at the NWS. My X20XEV first registration 01.06.1995 should therefore be an X20XEV B1, right? Oh yes, the sensor is from Hella via Metzger, No. 090307 Now to the actual question, and maybe someone is also so nice and likes to put it in the FAQ. W Elchen Sensor exactly I need and/or which engine generation, reverberator or impulse generator, and how can I distinguish these two differences? Thank you and a sunny weekend Alexander
