How to replace the MAP Sensor on Buick Terraza?

You should start by taking off the intake manifold cover before you replace the Manifold Absolute Pressure Sensor. The first step involves disconnecting the engine harness electrical connector from the manifold absolute pressure (MAP) sensor followed by MAP sensor bracket bolt removal and bracket detachment. Check the MAP sensor seal for damage following removal of the sensor. Replace the sensor seal if damaged. Before installing the MAP sensor back into its position, install a new seal (if needed). After installing the MAP sensor bracket keep its bolts tightened to 25 N.m (18 lb ft). Plug in the engine harness electrical connector to the MAP sensor then place back the intake manifold cover.
