I have a problem that I hope someone can help me with. I have a 99 Honda Civic VP and my check engine light is lit. I took it to an auto parts store to get it hooked up and they didn't even know what the problem was. It just printed out Speed Ratio or something similar to that. Does anyone know what kind of sensor this is and about how much it costs to get replaced? This would really help.

 

wuts a civic vp?..but the check engine light could mean hundreds of problems..have u done any mods or anithing to ur car lately?
