P34A5 means the temperature reported for intake cam actuator A on bank 1 passes the electrical checks yet makes no sense. Nissan describes the code for the 2018 Pathfinder (R52) and the Infiniti QX60 built before 18 December 2017: the MIL came on after starts at ambient temperatures around or below 0 °C. The remedy in bulletin NTB18-016 was a new electric intake valve timing control module with updated software, followed by a position learning run for the actuator; the revised bulletin NTB18-016a hands this over to the reprogramming campaign NTB18-072. Timing codes such as P0011 must be fixed before this one. Away from that software case, look for a drifting sensor or a loose contact. Drivers usually notice nothing. Bank 2 is P34A9.

Likely causes

Software of the electric valve timing module (Nissan 2018: cold-start false alarm)
Temperature sensor drifting out of its expected range
Intermittent contact at the actuator plug

Symptoms

  • Check engine light on, often after a cold start
  • Usually no driveability complaint
