Hello everyone, new here, looking for answers! I have a 2001 sebring 3.0, the car runs fine, however the ses light just came on. The code is a p1400, manifold pressure differential sensor. I checked for vacuum leaks, fixed a couple, replaced the front(easy) valve cover gasket...it was leaking. I also just done some general maintenance to the car, oil change, air filter, etc. I reset the codes and all was well...for a day! This morning, the light came back on, not yet sure of the code, but assuming it's the same.

I had a diagnostic done at chrysler prior to performing the aforementioned maintenance. They were going to replace the manifold pressure sensor, change valve covers, redo the entire ignition system, etc...($2300.00) haha...they were saying all kids of crap needed replaced, so I figured I would do most of it myself, which I did. So back to the question.

What the heck will fix this code? Replace the sensor? Keep looking for vac leak? Please help!!!

On a side note, it does have a little blue smoke here and there, like a valve seal leak, possibly rings, but it has 125000 on it. Let me know any suggestions!

Thanks

 

start out with the sensor first what cant not be said is if the wires are good to and from the PCM.
