What P34A5 means
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.
P34A5 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 2.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P34A5
- Check engine light on, often after a cold start
- Usually no driveability complaint
Common causes of P34A5
- Most likelySoftware of the electric valve timing module (Nissan 2018: cold-start false alarm)
- PossibleTemperature sensor drifting out of its expected range
- Less likelyIntermittent contact at the actuator plug
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P34A5 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 3 | Mixed range: generic and manufacturer-specific codes. |
| 4 | Area: auxiliary emission controls (catalytic converter, EGR, EVAP). |
| A5 | The exact fault in that area. |
What to do next
- Note P34A5 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P34A5
What does P34A5 mean?
P34A5 means "A Camshaft Position Actuator Temperature Sensor Range/Performance Bank 1". P34A5 means the temperature reported for intake cam actuator A on bank 1 passes the electrical checks yet makes no sense. It is a generic code, so it means the same on every make.
Is it safe to drive with P34A5?
Drive gently and only to a workshop. With P34A5 the car can go into limp mode (reduced power) to protect itself.
Will P34A5 fail an emissions test?
Yes, it can. P34A5 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P34A5 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will P34A5 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
