could be code 17, code 1 and 7, or code 10 and 7. depends on how it's flashing.

long flash=10 and is about 1 second long
short flash=1 and is about 1/2 second long
codes are seperated by no light for about 2 seconds
once all codes are shown they will continue to repeat until the svc connector is unjumped.

code 17=vss
code 1=primary o2
code 7=tps
code 10=iat
