P1105 Nissan - 2000 pathfinder

Question

I've replaced both MAP sensor and the tubes connected. Service engine light is still coming on, still getting code p1105. what should I try next?

Answer 1

HI there,

This code is usually a result of a bad map/baro solenoid. This solenoid switches when you start the truck. The map is manifold pressure and the baro is barometric pressure. Basically when the truck isn't running the computer is seeing the air pressure and then once started this solenoid switches and shows the manifold pressure. When you have this code the solenoid isn't switching which results in this code.
