The speed sensor on a 1999 Saturn SL1 is under the transmission. It is below the fittings for the transmission cooler lines.
throttle posistion sensor or vacuum leak
if there is no camshaft position sensor then why am i getting codes for it and how do i eliminate those codes?
The sensor is on the transmission above the right drive axle two wires to it

My son's 1999 Salvaged/total Saturn SL1 was rebuilt using many engine and body parts from 1995-1999 Saturn SL1 and SL2 cars, I believe it will work fine. I do not recommend before 1995 or 2000 or later models. I do not recommend SL2 either. I am not the expert but most of my son's engine is not 1999 SL1. Good luck!
Has the engine coolant temp sensor ever been changed.
bad fan or bad fan relay
.040

On the 1995 Saturn SL1 The oil pressure sending unit is the sensor closest to the alternator. The unit is on the back of the block.
