Question

I have a 2009 jeep warngler Sahara unlimited. It is throwing codes p2173. P0441, P0507. The P2173 is say a vacuum leak. Where do I start looking?

Answer 1

P2173 High Air flow / Vacuum leak detected (slow accumulation)

P0441 Evaporative purge system performance

P0507 Idle speed high than expected

You have 2 code that confirm the vacuum leak is valid. P2173 and P0507. What stands out is the code P0441 will set when the FTP (fuel tank pressure ) sensor see that its vacuum is lower than expected. so if anywhere it with the purge valve system . The purge solenoid is right near the battery either the purge broke , or the hose broke there. you can probable hear the the vacuum leak as it would make a hissing noise.

​ Right near the battery is the purge solenoid look at the hose from being disconnected.
