2007 Lexus ES 350 220k miles,0340 Sensor A Bank 1 camshaft position sensor. Car started with misfire codes and then P0606. I did valve covers and replaced plugs and coils. Then replaced the battery I got alternator checked and it was spiking so I replaced it Now at higher RPMs the 0340 code comes on. I replaced the camshaft position sensor and it still came on at higher RPM. So I took the new one and switched it with one of the other camshaft position sensor and still got the code I checked the wiring and looks ok, I also tested the output to the sensor and I was getting like 5.1 volts with the key on. I am at a loss and looking for advice, I am tired of spending money and time on this. Thanks!
and then P0606.
