2004 Infiniti i35 140k miles
After doing the brakes, spark plugs and valve covers, my speedo/odometer does not work. ABS/TCS lights are on. From time to time especially early AM the speedo works for about 10 minutes with the SLIP and TCS lights on (no ABS) but then reverts back to ABS/TCS when fails.
RPM does not show on dash but registers on scanner. Replaced sensor on transmission and no luck.
Long crank before starting - 5 seconds or so. Replaced crankshaft position sensor per error code P0335 from scanner but still a long crank.


other codes U1001, P1212, P1574, P0725. Not sure where to go from here.

Hi did you ever figure out the issue I’m having the same problem.

I didn't end up fixing it but I was told it was some module under the seat that needed to be replaced. I believe the abs control module.

Or the speed sensor are dirty and need to be cleaned...a wire wheel attached to a drill or die grinder works best!
