2002 Buick Regal Repair Question
Asked on February 2, 2009
2002 Buick Regal Service Engine Soon Light
Engine Mechanical problem
2002 Buick Regal 6 cyl Front Wheel Drive Automatic 160000 miles
My service engine soon light came on a week ago, I went to an auto parts store and they checked the codes for me, either Mass Air Flow Sensor, MAP Sensor, cracked or loose throttle body hose, or cracked or blocked vacuum hose. I changed Mass Air Flow Sensor and checked throttle body hose and my service engine soon light is still on. Before I spend another $60 for the MAP sensor, I was wondering if you could tell me where the vaccuum hoses would be or if you new of anything else I could try?

What was the actual code? Any sensor related codes, I always check the sensor circuits ,first. As far as the map sensor, the circuits are ref voltage--ground--signal, plus it needs vacuum.
