6.0 Sub 0 Temps

Ok I have a cold weather problem with my 04 6.0. When the outside temps reach 0 degrees f and my intake temp reaches below 4 degrees, I seem to loose boost. Its like the "VGT" does not work and once I get to above 2000rpm I finally start getting boost and holy cow hold on. I understand these really cold weather days/nights are brutal on any vehicle. Mods are K&N custom intake, 6.4 banjos, 4" down pipe to 5" straight pipe, blue spring upgrade, EGR delete, sinister coolant filter, and Edge CS running Level 3 towing mode (not currently towing though). I have recently done an oil cooler replacement. Any Ideas on why I loose boost...Intake freezing??? Also when I let the truck sit idling for a minute and intake temps hit above 10 degrees I get full VGT boost back. So after this happened I performed a diagnostic test via EDGE CS, these are the codes that came up...P0069 MAP Barometric Pressure Corelation, P0299 Turbo Supercharger Underboost, P0036 CKP Sensor A Circut range / performance, P0408 EGR sensor B circut High, P0488 EGR THrottle Position Control Range/Performance, P1000, P1334 EGR Throttle Position Sensor Minimum Stop performance, P2290 ICP too low. The check engine light was not on with these codes. Any help PLEASE!!!!

Wats your oil and coolant temp when this happens? Icp low - that code may be an unrelated issue but also need to check that out.

EOT 198 ECT 186. I know I have an IPR problem. Had a no start issue a few times, took the IPR out and the tip with the screen is broken and stuck in to HPOP. Have new HPOP and IPR to put in but working 7 days a week dosnt leave me much time to do it. Also noticed the trans temp about 20 degrees warmer when I lost the boost. Normally trans runs about 140ish but was 167 on the drive in today.

Take a look at MAP and BARO with koeo. They should be the same. Does your engine have a throttle position sensor or is the "sensor" a dummy? Could be sticking vains, but that map baro code seems like your map sensor may be bad or a chafed harness.

Not exactly sure what koeo is? Isnt the tps sensor located near the intake elbow? Really cant complain because the truck has 180k on origional everything including the EGR and cooler which is now deleted. But it just seems like everything is taking a crap at once. When I do the HPOP I want to batmowheel the turbo and do a detailed cleaning also. So maybe the veins are just sticking and worsening when its cold. IDK, but someone on here once said the more you know about the PSD, the more you realize you dont know.

^ you are so right! Im still learning and its difficult to diagnose.

Koeo- key on engine off. Map and baro should be the same.
Yes the tps is under the elbow. There is a (if i remember correctly) 4 pin plug that connects to it- some trucks have the sensor, others have a dummy and is just a peice of plastic... If you are getting that code, along with ckp circuit codes, you might have chaffed wires. Im assuming the egr codes are because of the delete. Sticking vanes or unison ring isnt neccessarily cold related. Once you start the truck and egt gets up to 350, zero degree ambient temps dont come into play. Its the cleanliness and wear on the ring and vanes. Your headed down the right track with cleaning... In short, if your egr is deleted, ebp, map, tps and maf will affect vgt performance. If your vanes stick it will sometimes throw a under/overboost, and can cause the other sensors to act up too. While idling unplug the vgt. See if you hear a noticeably different sound.

Well......Lets add insult to injury. Last night leaving work there is a large bridge on I-75 here, while driving up the bridge i heard a whooshing sound and all of a sudden my boost gauge pegged at 39psi. I am sure it was higher because the sound got higher and higher. It was so loud I kid you not a jet plane would be jealous of the sound. I seriously thought one of the heads were going to pop out through the hood. I got off at the next exit, and parked the truck. Lets just say at idle it was at 4psi of boost and it was hard to stay stopped, had to hold down the brake pretty hard. 25MPH it was about 22PSI. Now I am throwing P0470 Exhaust backpressure sensor circuit malfunction and a P0611 FICM performance in addition to all the other codes I listed earlierI think its time to take the truck to a shop. AAANNNNDDDD the wife bought a For Sale sign last night, said its time to go.

But I do plan on checking the TPS sensor. And checking the koeo. Luckily I actually get a few days off here too!!!

It is likely that your EP sensor is plugged, biased electrically, or the tube is restricted. The TPS on the intake elbow is just to verify EGR throttle plate position on vehicles equipped with EGRTP. Since a 6.0L Ford diesel uses ICP to drive the injectors, which is controlled by PCM via the IPR, a throttle plate for air intake control is not necessary. The APP/ pedal assembly is what tells PCM how much fuel you would like to add. EGR throttle plates can stick closed, restricting air flow, but it wont typically create the situation you have described.

Your exhaust back pressure sensor and tube is freezing at those temps. Get a new tube then pull and clean the sensor
