Rockrunner99 Posted July 7, 2021 Report Share Posted July 7, 2021 New to us 2015 Edge sport, took it to the shop after the engine performance went down and white smoke appeared from the exhaust. Ford claims a P1026 code and to replace either the PCV or Purge valve. Since the car has a 90 day warranty on it they are pushing back hard not wanting to do anything right now. The pcv is not part of the powertrain and they want $400 to diagnose and replace. I think it has more to do with the cooling system or EGR. It is true that the PCV can cause smoke and poor performance but I've never had a code with it, especially not a P1026. Any ideas would be greatly appreciated, the picture shows their diagnoses.

1004ron Posted July 7, 2021 Report Share Posted July 7, 2021 You might want to try a better image - impossible to read that even on a large monitor. You don't have an EGR. How's the coolant level ? Get the codes read at Autozone and post them here. Quote Link to comment Share on other sites More sharing options...

Ford's solution usually includes an updated valve cover. https://www.ecoboostperformanceforum.com/index.php/topic,496.msg78981.html#msg78981 Quote Link to comment Share on other sites More sharing options...
