How to compare pattern of left bank and right bank sensors?

Simple.Try this.

Put the pico scope tool on the camshaft sensors and compare the pattern for the left bank to the right bank then compare the correlation timing of the crankshaft position sensor to the left bank VVT sensor and also crankshaft position sensor to the right VVT sensor and see if there's any difference between the right and left bank VVT sensors. Before that pull the connectors from the sensors and check for pin fit, corrosion or any rodent damage to the wiring harness.

This will help.

Thanks.
