White smoke and P1026 DTC

Recommended Posts

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.

even tho MY and obd code are not included in the tsb

Issue: Some 2016-2017 Edge/MKX, 2017 Continental, and 2017 Fusion/MKZ vehicles
equipped with a 2.7L or 3.0L gasoline turbocharged direct injection (GTDI) engine and
built on 1-Apr-2016 and through 1-Jan-2017 may exhibit white or blue smoke from the
exhaust, rough idle in neutral or park at normal operating temperature or after a hot
restart. The vehicle may also exhibit an illuminated malfunction indicator lamp (MIL)
with diagnostic trouble codes (DTCs) P0300, P0301, P0302, P0303, P0304, P0305,
P0306 and/or P0316, P0524 and/or P06DD with excessive oil consumption. Oil
consumption may be 1 Liter (1 quart) in less than 4,800 km (3,000 miles).

 

yes, PCV can cause smoke issues, and performance issues (it leans out the A/F mix).  and it has on the 3.5 EB transverse setup.  Ford's solution usually includes an updated valve cover.
