What does P0106 mean?
P0106 — Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem. This is an OBD-II diagnostic trouble code a scanner retrieves when your vehicle's computer detects manifold absolute pressure/barometric pressure circuit range/performance problem. The level of risk depends on how the vehicle is currently running and how long you've been driving with the light on.

How to fix P0106
- Check the MAP sensor vacuum hose for cracks, plugs, or blockage
