Keith Browning Posted August 15, 2011 Share Posted August 15, 2011 I am chasing down another P00B7 code. Anybody actually perform PPT K2? Are they kidding? Yea, just like that. Disconnect the ECT sensor. Seriously? What have you guys been coming across on thes DTC? Quote Link to comment Share on other sites More sharing options...
Fordracer Posted August 15, 2011 Share Posted August 15, 2011 P00B7 doesn't send you to PPT K2. Were you just messing around and looking at all the PPT steps? I haven't had a code yet that sends me to K2. Whenever I have that code I end up at K9 and replacing the thermostat. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted August 16, 2011 Author Share Posted August 16, 2011 Yes, I was perusing the entire K tests. Usually accessing and disconnecting a sensor to perform a test is not too big of a deal. The ECT on a 6.4L is not easy to access let alone disconnect. We have another 6.4L in the shop with the shroud and stator odd and the connector was still a pain in the ass. I am probably looking at a thermostat but the last one I came across needed an oil cooler. Quote Link to comment Share on other sites More sharing options...
mchan68 Posted August 16, 2011 Share Posted August 16, 2011 Isn't 00B7 the code that seems to set most frequently after 11b23 is done? Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted August 16, 2011 Author Share Posted August 16, 2011 Ah, yep. You gotta love it when a truck comes back shortly after being in the shop for a re-flash. Makes for happy techs and happy customers. Quote Link to comment Share on other sites More sharing options...
sixturbosix Posted August 19, 2011 Share Posted August 19, 2011 Tech that works beside me had one with this code today and this is what he found.Cavatation under the thermostat.I had never seen this. Quote Link to comment Share on other sites More sharing options...
Mekanik Posted February 13, 2013 Share Posted February 13, 2013 Interesting... I've got one right now with that DTC. The pinpoint test leads right to the thermostat, but the thermostat was JUST replaced at another Ford dealer. Will this DTC cause a lack of power and a wrench light?

Mekanik Posted February 14, 2013 Share Posted February 14, 2013 I guess it goes into a failsafe mode. I set him up with a flight recorder and he's going to return. How can I tell if I've got a plugged oil cooler, is it like on a 6.0L? Quote Link to comment Share on other sites More sharing options...
Mikill Posted February 14, 2013 Share Posted February 14, 2013 Usually if the coolant level is correct and there are no leaks the it's mostly likely thermostats. I have had a couple where they were recently replaced and code returns because of damaged t-stat housing. Quote Link to comment Share on other sites More sharing options...
Aaron Posted February 14, 2013 Share Posted February 14, 2013 I just put stats in my truck when I replaced my radiator, and warm up times are significantly longer now, and it loses ECT in a HURRY at idle after cruising on the highway.

They slots where the thermostats go into get worn out or cavitated which causes the thermostats to pop out of the slots. Quote Link to comment Share on other sites More sharing options...

You'never guess what I found when I took the thermostat housing off... The ORIGINAL thermostats. There is NO WAY they were JUST replaced.

There is NO WAY they were JUST replaced. So they likely ended up in another tech's toolbox. You know, this sounds exactly like a situation I had been through years ago on an E-Series that wouldn't start once up to operating temperature. The OASIS also showed that the STC had been replaced recently, so here I was chasing a high pressure oil leak that sounded like it was cover from the STC as well. Low and behold, when I pulled the pump cover, it still had the original STC. Quote Link to comment Share on other sites More sharing options...

Once I spent years dealing with a Ford Probe with an engine noise that some other tech did a TSB for a cam gear that would take care of this noise. FINALLY I took the thing apart to re-replace the cam gearand fixed the car. The thermostat seals were coming apart and they were most definately original.

Aaron Posted March 5, 2013 Share Posted March 5, 2013 You can tell by the bypass openings in the thermostat plate as well, they changed shape when the part number changed. Quote Link to comment Share on other sites More sharing options...
