I'm getting a check engine light code 46 which is barometric pressure/manifold air pressure sensor high.Can anyone tell me what this is and how to fix it.

 

If its running good,no idle problem or backfiring problems,just take off battery lead for about 30 seconds and see if code comes back. If comes back,could be indicating voltage drop or spike in map sensor harness. Kits are available if you are having problems. OPT

 

Check the 4 wires on the T-BAP sensor, I have had the wire connector replaced 3 times, and the last time the tech re-enforced the wires and left the harness loose allowing for engine vibration. The engine does vibrate A LOT and the wires in the connector are very small too small IMO. Next time I have an old sensor a will solder larger wires on the sensor male pins and make my own connector.
