[urq] UrQ frustration

[Mike Del Tergo]

L-A,

the one on the bell housing is the speed sensor, the one one the lower drivers side block is the reference mark sensor that I think is bad. (though both have the same PN) Both look pretty easy to access though.  Destroying the sensor would still leave you with the 2 allen screws to remove however, no?!
