Guys, please forgive me but I didn't know where to turn. My wife has a 2000 Sable with the 3.0L DOHC. I'm not sure if this is the same 3.0L as in the Ranger but I figure someone might be able to help. Last week the check engine light popped on and since I was near an Advance Auto, I slid in to get them to check the code. It was something like "insufficient EGR flow". No problem. I replaced the EGR valve, pulled the battery cables for about 30 minutes and went on my way. Sure enough, about 20 miles later, it pops back on.

I "decarboned" my 4.0L Ranger last year per the instructions here on the site (with the PM-3). Is there a way to "decarbon" this engine as well? Should I even look for some other "fix" first?

As always, thanks to anyone for their help and opinions.

P.S. If it matters, this engine has about 80,000 miles.

I have a 2000 sable as well and had the same problem at about 90k mi. Mine turned out to be the DPFE sensor (flow sensor). A new one cost me about $35-$40 at a Ford dealer and it's easy to change.

 

That's what it was. Where is that thing located?

 

It's on the the back of the top back of the engine towards the firewall.

 

Wow, I guess early in the a.m. I should read what I type before I hit submit. That previous post made no sense.

It is on the top of the engine on the back towards the firewall. It is a small block with 2 tubes and a wire going to it.

 

LOL. Thanks for the help.
