I was hoping someone could help me ive got a code in my computer that wont delete it says, manifold pressure sensor short with power G71 p1155 intermittent.

Manifold pressure sensor power supply p1157 intermittent.

Ive changed boost sensor,air flow metre,re wired were i found a broken wire for map sensor with plug an wiring from tps. Use to get power back after pump staring it while driving but since re wiring an changing map sensor just constantly stays in limp mode. Also changed black vaccum solenoid box too.

Has the broken wire blown any fuses?
