It's just strange that 10 quick blinks is 10 and that should just be one long blink. And I don't know what fault code 70 is.

If you remove the sensors be careful they go brittle and generally fall apart

I think because it didn't flash up a code 17 (Vehicle speed sensor), it goes to suggest it's more than likely your actual clocks (or at least the connection/wiring to it.
