P34A7A Camshaft Position Actuator Temperature Sensor Circuit High Bank 1
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P34A7 is set when the temperature sensor of intake camshaft actuator A on bank 1 delivers a voltage above its upper limit. Most often the sensor wire or its ground is interrupted, or the signal touches a supply voltage; with an NTC-type sensor this reads as an implausibly cold actuator. The module then lacks a usable value for its thermal protection and usually switches to a cautious phasing strategy. NTN-SNR assigns P34A7 to the inlet camshaft adjustment with too high a signal. Nissan fits such sensors to the electric intake phaser of the 2018 Pathfinder and QX60 but has not published this particular code. Check the actuator plug and the harness routing over the engine first. Low is P34A6.
- What you may notice
- Check engine light on
- Intake phasing on bank 1 reduced
- Mostly no noticeable effect while driving
- Likely causes
- LikelySignal or ground wire of the sensor interrupted
- PossibleSignal wire shorted to a supply voltage
- PossibleSensor open internally
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €50 – €700
