my check engine light is on and i checked the ecu and it gave me 3 codes which were:
code 6- coolant temperature
code 9- no.1 cylinder piston
code 17- speed sensor

can anyone tell me what each code means and what im supposed to do to fix the problems?

 

6) Engine coolant temperature sensor (on my cars) is located in the side of the head, near the upper radiator hose. Some years Honda put it in different locations, so what car are you talking about?

9) CYP sensor is located inside the distributor.

17) VSS - vehicle speed sensor is probably on the transmission, depending on what car you're talking about.

Each of these problems can be either a bad sensor or bad/corroded/loose/dirty wiring.
