My p73 has been throwing a "check engine" light on my GS-R and when I step on the gas it boggs the car down alot. Ive checked on it and with my stock OBD2 p72 it says the "crank positioning sensor" is out but when I put the p73 it gives me a code 9. If I put a OBD1 p72 the car works fine. Any1 got any ideas?

 

check ur sensor

 

naw, i know that the sensor is out but the p73 shouldnt even be seeing it, and thats what im trippin on.
