i had code in my Lexus which is P1346 and P1351 that stated VVT sensor performance rage for both bank 1 and bank 2
the question is where is VVT sensor located ?
and does any one had faced these codes before and how he repair it .
I suggest you to read this thread although it's about 1UZ-FE.
As far as I have experienced, the simultaneous P1346 and P1351 together is often caused by the skipped timing belt of 1 tooth.
Couple of questions
Are any of the cylinders misfiring?
and did you do a service recently?
If cylinders 2,4,6,8 are misfiring then its the bank2 VVT sensor and if 1,3,5,7 are misfiring then its the bank 1 sensor.
Replacing the Sensors is easy, its just plug and play. But if the codes do not go after replacing them something is wrong with the timing of the engine.
The circled sensor is the bank1 sensor its on the same place on the other side aswell
thanks for the kind information
in fact there is no any misfiring in engine , and there is no any roughness .
i think the timing issue
