So, I shut the key off and proceeded to take the hose off of the EVP and unhook the wiring connector and then start the car to see if there was a vacuum leak through the valve.
Today my wife came home and said CEL was on, so I connected a bluetooth OBD2 reader (like I have done before) and read the codes, a P144a, which has something to do with the EVP. will I need to take it to a dealer to have them flash the Air Bag Code? View 14 Replies Ford Wiring/Electrical :: 2009 - CEL On With Code P144a - No Start - Key Fob Not Working? I googled this topic, and still can't seemed to find this. So, how does one reset or clear this 52 code - I know that it was a result of me pulling that fuse, as the light was perfect before, and no issues. I pulled the right kick plate, and see the AIR BAG module, etc the fuel inheria switch mounted on the firewall, but no sign of that 2 prong plug. It's a 96 OBD II - so I don't think I can do the "short the 2 pin gray connector" trick, or can I? I pulled the wrong fuse, and now my air bag light is flashing a 5 2 pattern, and then stays on continuously.

I just took the car to an Auto service place and they came up with the code P144A. The car wont pass inspection (required in MA). Waveform is similar even with a swapped coil and plug.Ford - Escape :: 2010 - Engine Light Stays On Continuously - Code P144A The spark also looks weak as compared to a good cylinder as well, but to be honest I'm not sure if that's just down to my scope settings or not.
The burn line from the initial firing stays straight as an arrow directly into the second firing. Ford uses a multi-strike/spark ignition strategy at idle and on the trouble cylinder the second firing looks odd. Upon scoping the secondary ignition though I found something unusual. All 8 cylinders were pretty much identical). I have also scoped the injectors, again all looked fine (at least I think they did. I am a pretty new scope user, but I have ran a relative compression test which looked just fine. Swapped #4 coil and plug with Cyl #1 and the miss stayed put at Cyl #4. With the cylinder disabled it drops down to a steady -80%.
#4 exhibits about -20 to -40% low contribution via cylinder balance test at idle (ran on an Autel MaxiSys). It is not a dead miss, but pretty regular and sets a P0304. I have a 2010 F-150 5.0L in the shop that has a #4 cylinder misfire. Wish I discovered the site sooner, great resource!
