Third site I have visited and have three different answers for “where is the Camshaft position sensor”. So who is right? I don’t know. It seems that the Camshaft position sensor and Crankshaft position sensor is in the same place. If anyone has some clarification on this it would be most welcome.
Thank you
I know this is way too late but for future reference and too people who visit this site in the future. this sensor location diagram is for a 4th generation engine. the crankshaft and camshaft sensors are located on the front of the timing cover. Top being camshaft and bottom being crankshaft. on a gen 3 or gen 5 motor the locations are different. I believe gen has the sensor located on the rear of the block.
