Manifold absolute pressure sensor circuit high?
Hey guys, my engine light turned on last night and the code is P0108 which means Manifold Absolute Pressure Senor Circuit High. What does this mean? Is is something I need to rush the jeep to the shop over?

I installed a Unichip a few weeks ago, could this be the cause? I've unplugged the battery for 20 min and reset it, it stayed off the rest of the night, but came back on this morning.

All bets are pretty much off with the Unichip but this could also be the throttle body table being changed and the blade being open greater than what the MAP sensors believes it should be.

hmmm....well it has a throttle body spacer on it, but it's been on since it was brand new. It has 4500 miles now. So you think I need to take to the dealer then?

And don't bother to reinstall the throttle body spacer after.
