Cadillac: cadillac eldorado 94 error codes, rear wheel speed, cadillac eldorado

Question
I wanted to know if you could elaborate on these error codes that I recieve from my onboard computer here they are as follows:

- P036 HISTORY
- T037 CURRENT
- S060 HISTORY

I have cleared all my codes and these are the ones that came back after a day of driving. Also I want to paSS SMOG and i needed to know what is the easiest protocol to ensure a passing grade, i was told these cars are hell to pass smog with.

               Thank you

P036 = EGR valve pintle out of position.

T037 = Left rear wheel speed sensor continuity failure.

S060 = Left front position sensor fault.
