I have a 97 civic ex b20b block and b18 type r head turboes and im getting the cel 8 wich is the tdc sensor. My question is what it could be its not always on i can drive it for a week or two and it will never cut on but then out of the blue it cuts on. If i cut the car off and turn it back on it could be another week or so before it cuts on again is there any way to check it without taking it out like maybe if there is something in the wiring what would i need to do ima noob to hondas.
