  Q: How to replace the Mass Air Flow Sensor on Buick Lucerne?

  A: The first step when replacing a mass air flow (MAF)/intake air temperature (IAT) sensor is to handle the Mass Air Flow Sensor carefully while protecting it against damages by touching only the specified parts and keeping it free from solvents and lubricants. A limited amount of soap-based solution helps installation procedures. Start by removing the intake manifold cover before you detach the engine harness electrical connector from the Mass Air Flow Sensor/iat sensor. To remove the air cleaner outlet duct the technician needs to loosen two clamps: one at Throttle Body and one at Mass Air Flow Sensor/iat sensor position. Remove the bolts securing the Mass Air Flow Sensor/iat sensor followed by pulling out the sensor from its position. The installation requires repositioning the Mass Air Flow Sensor/iat sensor followed by tightening its bolts to 4 n.m (35 lb in). Reassemble the air cleaner outlet duct after securing the Mass Air Flow Sensor/iat sensor clamp to 4 n.m (35 lb in) and the Throttle Body clamp also to 4 n.m (35 lb in). The final step includes reconnecting the engine harness electrical connector to the Mass Air Flow Sensor/iat sensor followed by reinstallation of the intake manifold cover.
