P0107 map
 

I have a 1999 Saturn SL2. It runs poorly (limp mode?). Codes are: P0107, P0341 and P0404. I am most concerned with the P0107. I have replaced the MAP sensor with no change in condition. I have checked the 3 wires in the MAP sensor and I have good power, ground and signal.

I am thinking the problem must be the signal wire between the MAP sensor and the PCM. I will check that next. Anything else I should be checking? Thanks!

That would be a good thing to check. Verify that intake manifold pressure is actually reaching the MAP as well.

Another example of where live-data can check it (the MAP system, in this case) in mere seconds.
