This is actually an easy swap out. Remove the electrical connection, remove the retaining bolt and pull out old one. I believe the sensor is located in the front passenger side of the engine on this particular model.

If you have bearing problems MAP sensor codes are the least of your worries. Check on the cost of getting a new engine. I hope this is not the problem. Good luck Moe

Hi there, Best thing to do is buy a Haynes or Clinton's repair shop manual at your local AP store for your particular vehicle. Then read up on it in the trouble shooting section or the step by step RR section. You can purchase these at your local Auto Parts store or buy them on line at ebay burdfrenzy
