Re: VW Polo 2002 1.2 16V AZQ. Code P0172 Archived Message Posted by john weddup on September 2, 2008, 8:37 am, in reply to "Re: VW Polo 2002 1.2 16V AZQ. Code P0172" Have you tried revving engine to see if map sensor responds. Clear fault codes first after disconnection. On overun engine vacuum should rise with throttle closed if no response then probably map sensor fault. I normally hope for 23 inches mercury but not sure if those 3 cylinder engines will acheive this. John Message Thread: VW Polo 2002 1.2 16V AZQ.
