Hi,
I'm not 100% sure I know what you are looking for. There is a sensor, but the timing is done off the camshaft timing control pulley. The codes could be the result of a few different things. For example, timing, a failing timing control pulley, and so on.
Here is the interesting thing. You have exhaust timing issues on both sides. I'm questioning if there is an issue with one of the timing chains.
Regardless, I attached the diagnostics for the two codes related to the exhaust cam timing. Take a look through them and let me know if you are comfortable performing them.
Take care,
Joe
