Please help with the folling codes p0132 p0138. Both O2 sensors have been replaced. What does the Map sensor do? And what does it stand for.

 

p0132 front o2 shorted
p0138 rear o2 shorted
first, try this..
disconnect both o2, make sure you don't have any spread pins on both side of the connectors, look very close. spray both sides of the connectors with brake cleaner, then use a blow gun to get them completely dry - reconnect them. if the check engine light comes back on you need to do your voltage and ground check at the o2 connectors, it may be a bad pcm.
Does anyone know of a forum similar to this one but for Chrysler-Dodge-Jeep Dealer techs only?
