Hi guys its Bryce again, the worst IS owner in history. i have a question im hoping someone could give me some advice on, since buying parts locally for our cars is out of the question, and the return and restock fees of parts online make it cost prohibitive gambles.

for over a year now , my CEL trips and throws codes for both Cam sensor banks and Crank. it goes away. I believe its likely 1 sensor failing and showing malfunction for all sensors in the circuit. but how can i figure out what the problem sensor is without manually checking each with multimeter or hooking up toyota techstream? i guess i could replace them all, but i believe the crank sensor location is difficult to reach? just wondering if anything specific to out vehicles you could give insight to . thanks.

EDIT: realized i didnt specify out of the 4 sensors which ones are tripping, i believe the code said BANK A and BANK B, no other info
solved
SOLVED: cam sensors run on oil pressure. went back to 5w-30 Mobil Synthetic. problem solved.
