P0022code -Camshaft position timing over-retarded Bank 2 and P0316 misfire detected on start-up causing engine light to be on dash panel. How many sensors does a 4.6 litre engine have Where are they located?
If you start replacing sensors just because codes come up you will be spending an atrocious amount of money with no results. Especially in this instance. Your sensors are probably working. They are sensing something is wrong with you variable timing system. The best thing you can do is take it to the shop and have them properly diagnose the problem and fix it. One of the “sensors” you are concerned with is the ECU. It is probably okay, it’s just telling you somethings wrong. Wouldn’t it be silly to replace such an expensive part just because it’s doing its job?
