Gents,

I've changed my sparks, packs, cats and STILL this damn code shows up WTF:
P1000 (249) LeakageDetectionModule - leak detected

MAF?

 

Maybe. Read all of the above advice. I’d clean the MAF before replacing it though.

 

What are you using for a code reader? I suggest elm327 and torque app. I have not seen that code but occasionally there are issues with the leak detection system in the evaporative emission system. The purge valve is a common issue, but have had other issues.
