P34A9A Camshaft Position Actuator Temperature Sensor Range/Performance Bank 2
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P34A9 covers the plausibility check of the temperature sensor at intake cam actuator A on bank 2. Nissan names it together with P34A5 in bulletins NTB18-016 (2018 Pathfinder) and ITB18-009 (2018 QX60): vehicles built before 18 December 2017 could store one or both codes and switch on the MIL when started in freezing weather. Nissan traced this to the electric intake valve timing control module and first replaced the module with one carrying newer software; a later revision moved the fix to a reprogramming campaign. If P0021 or other timing codes are stored, they take priority. Outside this case, a sensor whose reading wanders or a poor contact at the bank 2 actuator are the candidates. Bank 1 is P34A5.
- What you may notice
- Check engine light on after a start in freezing weather
- Engine runs normally in most cases
- Likely causes
- LikelyModule software (Nissan 2018 Pathfinder/QX60, reprogramming)
- PossibleSensor reading wandering or slow
- RarePoor contact at the bank 2 actuator plug
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
