'96 328i conv E36 P0500 code. Had bad differential sensor and connector. I repaired those two items which made my speedometer work but still no speed indicated on scan tool when driving. The brake/abs light is on but that shouldn't be an issue for a P code. The cruise control works also. I'm having a hard time even tracing on wiring diagram where the signal goes. I see it's from diff sensor to instrument but not where it goes to engine computer.
Nevermind. I figured it out on my own. Please cancel and do not bill me. Thanks anyway.
