I recently noticed the check engine light was on in my 97 QX4, So I hooked up a Actron Diagnostic Tester and got a code P0105 Map/Barometric Pressure Circuit Malfunction! Would a good point to start be the Map/Baro Switch Selenoid Valve, or just the Map Sensor?? If anybody has dealt with this problem or can be helpful with answers I would greatly appreciate it!
