DiagnoseDan spend a while tracking a non start issue to a new aftermarket crank position sensor that was wired opposite to the genuine article… There were waveforms and to the untrained eye it looks almost perfect… but he noticed an inversion so he swapped pins and the vehicle started…
Same issue could in theory occur with sloppy aftermarket parts supplier unless that supplier has actually physically tested the part on that model rather than just looking at dimensions and some loose compatibility issues and saying it’s ok… And I’d not want near enough on ABS/ESC function…
So if one goes aftermarket parts, they do need to be checked in detail, both mechanically and electrically/electronically which may require a cro and looking at waveforms… Me, I can’t be faffed with doing such unless there's a huge difference in price that covers my effort
