P34A8A Camshaft Position Actuator Temperature Sensor Circuit Bank 2
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P34A8 mirrors P34A4 on bank 2: the module detects an open or otherwise faulty circuit at the temperature sensor of intake cam actuator A on the side without cylinder 1. Only V and boxer engines have this bank. The one documented user of the family, Nissan's electric intake valve timing on the 2018 Pathfinder and QX60, monitors both banks separately (range codes P34A5 and P34A9), yet P34A8 itself turns up in no manufacturer document we could find. NTN-SNR describes it as an electrical fault of the inlet-side temperature sensor on the second bank. Typical findings are a corroded plug, a chafed harness near the cylinder head or a failed sensor. Range, low and high are P34A9, P34AA and P34AB.
