I am stumped. I am having a issue with a sensor. The ODC ll code I am getting is PO335 which is crankshaft sensor position circuit A malfunction, This sensor was replaced and the same error code keeps coming up. The sensor that plugs into that sensor actually has a loose wire and needs to be replaced, but I do not know what sensor that particular one is. It plugs into the crankshaft position sensor and then runs down the side of the engine and bifercates into two sensor plugs that are attached to the block. Nowhere in any books have I been able to find the name of that sensor, This whole problem came about after I had the water pump replaced. I got the car back from the shop with the check engine light on and this sensor error code.
