just had a 17 with a bad cylinder head gasket. truck was stock ( no performance parts/flash) YOU should be able to get it to build high cooling system pressure when the engines cold as well IF you have a gasket issue. I power braked it (f550 with a ultility box) and the pressure gauge would climb like a boost gauge.

ive done a lot of clutches, straight forward. I leave the shroud in and unbolt the fan from the clutch. be careful witht he harness and connector attached to the long 13mm w/p bolt

after letting the truck sit and at 4am i can navigate nyc streets at 5mph i tried the procedure again and it went away. still not confident on what just happened lol

what does the dpf pressure pid read? what about the ebp?

ive done close to a dozen now, both for sensor failure and oil leaks!

it sucessfully regened but light didnt go away, here in nyc we drive slow lol but i cant limp it at 4mph to be continued for now

ill give it a shot thanks.

morning all, have the engine idle only see manual fault on the dash. found a later pcm recal and tsb-14-0192 so I updated the pcm and followed the tsb 2x now and cant see to get it clear. made sure it was a cold soak, verified pid for reduct pressure was zero then watched it come up. as the injector square wave started I limped it around until it stopped then parked it revved it to 2k and waited for egt14 to reach 311*. well it reached it and then nothing I kept it going wil it reached 380*(15-20 mins after it hit 311*) and nothing. I did notice after it hit the set "311*" the injector would cycle every few seconds, I thought it was carrying out its own test but alas itll do it till it runs out of fuel. NO dtc's and I verified the def level is full and clean. what am I missing? thanks.

cleaned maf and all is well problem solved.

after using the last resort (google) i cam across some info also pointing to the mass air aswell. ill chk it in the morning. thanks

Truck came in crank no start, long story short dpf was plugged and the back end was starting to melt. Typical codes for soot accumlation and pressure performance. Installed a new dpf and all new sensors, reset the scr and dpf functions but it still throws a code p2463 soot accumulation within a minute of running. Dpf pressure was .05 and within 3 minutes pf running is .30 and inferred load is 150%. And says drive to clean exhuast. Almost makes me think i got a dirty motor. Seems to run ok but i did notice i have 2 injectors with +.02-3 grams of fuel at idle. Any run into his? Side note trucks been black listed by ford. 40k miles and 8000 hours its on its 2nd possible third engine

just finished one, was pretty easy knock the belt off and pulled the pump from the fender well.

the gaskets used in the dorman egr and oil cooler kits are bad news, ive never seen one do that BUT the Chinese egr cooler inlet hoses don't make it a month usually lol

Update, just a fuck ton of air. I stuck a long trans funnel init and filled that halfway up. Took 20 mins pf sawing the wheel back and fourth

Stuck fan clutch? Ive replaced a ton of them. Check the fan rpm vs engine rpm vs commanded % Raide the engine to 1200 rpm and the fan should only read like 6 or 700 rpm if its good from what i remember.
