Can someone tell me the location of the CAR on a 93 SC400

 

It's inside the distributor. If you're getting a check engine code for the crank position sensor it means your distributor most likely has an internal oil leak and needs to be replaced. On later years the Crank Position Sensor is elsewhere, but I know the first few years it's in the distributor. Or at least on the SC300 it is, hopefully someone chimes in to confirm or correct this in relation to the sc400
