Been searching posts and found that R32 GTRS seem to have the Hicas locating lugs at different positions My gtr is 89 and the Zero deg slot on the Sensor wheel lines up with its photo transistor in the sensor block when at 7-2 oclock My wheel which is factory GTR has the holes for the lugs at 12-6 so i get the old hicas error light after 10mins of expressway driving ( no turning) My wheel is in good nick for a 89 wheel so im thinking its off a later model and they are meant to have the 12-6 position for the lugs. Background: there are three photo transistors in the sensor block 2 of them switch the fine pulses with the rising edge of the pulses at 90 degrees apart this is called quadrature in my field(industrial electronics) so the computer can tell which direction the wheel is moving looks to be about 1 degrees per pulse but i didnt bother counting how many there are per rev to work out degrees. The other one is for zero degrees it lines up with one slot about 10 fine pulses wide so your zero degrees only comes on in one spot +- about 10 degrees This is how i can tell my car lines up at 7-2 oclock MY Question what R32 GTR Year models use 7-2 and what year models use 12-6

hi all I have the same problem with my r32 gtr 10minutes driving on the expressway (no sharp turning) and the hicas warning comes on. I have what appears to be the original wheel with the boss as part of the wheel so it cant be put on wrong position. there is a drive dog that locates the horn ring and steering angle sensor at the bottom and a 3pin socket for the horn wiring that locates at the top of the wheel so both are aligned vertical. there is a factory looking centre punch mark on the end of the steering shaft that lines up with the same mark on the wheel BUT on inspection of the zero degrees slot in the sensor disk it is about 160 deg right of the sensor. it all looks factory but either the wheel or the sensor must be from another model. Any help on how to id the right parts. the wheel is 3 spoke leather bound with leather gtr horn button about 50mm dia. Thanx
