P0108 on a Nissan: Causes, Fixes & Repair Cost
🟠 Moderate severity · drivable
Safe to drive, but the engine may idle rough, hesitate, and use more fuel until the sensor issue is fixed.
What P0108 means on a Nissan
On a Nissan, P0108 means the manifold absolute pressure (MAP) sensor signal is higher than the computer expects. Many Nissan engines, including several V6 models, use a MAP sensor, and a bad reading makes the computer misjudge engine load. That can cause rough idle, hesitation, and poor fuel economy.
Is P0108 common on Nissans?
P0108 appears on Nissans like the Altima, Sentra, and Maxima, usually from a failed MAP sensor or damaged wiring. The sensor itself is a common, inexpensive replacement once the wiring checks out, so the repair is usually quick.
Commonly reported on: Altima, Sentra, Maxima, Rogue.
