I have just purchased a 2005 Altima 3.5L SE-R with this code. The part store has either a front engine back or a rear engine bank but was unable to figure out which one was for this code. Could you tell me which is the correct part?
-
The P0340 code is the for the Bank 1, and the sensor for the bank 1 is the one by the throttle body. So is the rear of the engine, since the front of the engine is on the passenger side and the rear the driver side.
