rcrsn Posted February 5, 2011 Share Posted February 5, 2011 Check engine light has been on since Dec 14 2010, dealer informed me that no fix available at this time....will call me when "update is available from Ford" The engine lacks power and the DEF consumption has dropped...filled the DEF tank on Nov 27 2010... 15,000 km later and the dash monitor states the Exhaust Fluid Level is OK Hooked on to a empty 20 foot trailor...definitely NOT like before....need to pick your spot to pass any slow moving vehicles!!! What long term engine and exhaust system damage is being done while FORD finds a fix??? What is with the air box...stopped to assist a gentlemen with a 6.7....air box packed full of snow....5000 km on his truck and 3 weeks old. This reminds me of the 6.0 litre fiasco in 2004....and they say they rigorously tested the 6.7 before launch. :shades: :titanic: Quote Link to comment Share on other sites More sharing options...

Do you live where there is a lot of snow. For some people, the fix is simply to change the air filter (gets clogged with snow). Quote Link to comment Share on other sites More sharing options...
rcrsn Posted February 6, 2011 Author Share Posted February 6, 2011 Did a google on P164A O2 Sensor Positive Current Trim Circuit Performance (Bank 1 Sensor 1). Do you live where there is a lot of snow. For some people, the fix is simply to change the air filter (gets clogged with snow). Yes we live where we have snow and the air filter was changed just before the check engine light came on. Cleaning the air box out during snow conditions can be a daily event, know of 9 other trucks with the same code. The frustration is the driveability issue and Ford's failure to communicate back to their Service Departments when and what the fix might be!! These trucks aren't grocery getters they're work trucks and this is going on 2 months since diagnosis Quote Link to comment Share on other sites More sharing options...
Albitron Posted April 4, 2011 Share Posted April 4, 2011 Might be able to unhook the batteries to reset the comp and get it to the previous power you had before, but cannot promise this will be a fix for it. Quote Link to comment Share on other sites More sharing options...
Hydro Posted April 4, 2011 Share Posted April 4, 2011 (edited) there is a TSB for it. I posted this on the 6.7 reliability post. Look at the smilies... his article supersedes TSB 10-23-9 to add additional calibration content. ISSUE: Some 2011 F-Super Duty vehicles equipped with a 6.7L engine and built on or before 3/14/2011 may exhibit malfunction indicator light (MIL) on with diagnostic trouble codes (DTC's) P0401, P0402, P009A if driven at highway speeds with a snow plow attached, P164A if idled for extended periods in colder ambient temperatures, 2-3 transmission shift flares, harsh/inconsistent transmission shifting during transmission fluid warm up and tip-in events when at low speeds or coming to a stop. Refer to the Calibration Content for additional details. ACTION: Follow the Service Procedure to correct the concern SERVICE PROCEDURE Reprogram the powertrain control module (PCM) and the transmission control module (TCM) to the latest calibration using IDS release 71.05 and higher or 72.01 and higher. This new calibration is not included in the VCM 2011.3 DVD. The Calibration Update Contains Improvement Actions And Enhancements: DTC P0401 (exhaust gas recirculation (EGR) flow insufficient detected) DTC P0402 (exhaust gas recirculation (EGR) flow excessive detected) DTC P009A (intake air temperature/ambient air temperature correlation) if driven at highway speeds with a snow plow attached :shades: False DTC P164A (O2 sensor positive current trim circuit performance (bank 1, sensor 1)) if idled for extended periods in colder ambient temperature 2-3 transmission shift flares Harsh/inconsistent transmission shifting during transmission fluid warm up Improved shift feel for tip-in events when at low speed or coming to a stop Previously Released Calibration Content Previously released calibration content included in IDS software release 69.07 and higher contained improvement actions and enhancements to address the following: Calibration Content Vehicles Built On Or Before 11/5/2010 Delayed manual upshifts from 1st to 2nd gear when in Select Shift mode while going down a grade Harsh/delayed 1-2 upshift and downshift Harsh 2-3 upshift on first drive away of day after vehicle soak DEF warning messages won't reset after refilling DEF tank with Key On Engine Running Modified vehicles for rail applications, that will not re-engage PTO operation or speedometer inoperative after riding on the tracks with the front wheels off the ground VSOUT signal inoperable from customer access circuits under dash DTC P2463 or P246C (DPF restriction) and DTC P2459 (DPF regeneration frequency) - adds increased ability to perform manual regeneration at higher load values when performing system diagnostics Calibration Content - Vehicles Built On Or Before 08/23/2010 False DTC P132B (turbocharger/supercharger boost control A performance) False DTC P0299 (turbocharger/supercharger A under-boost condition) False DTC P050E (cold start engine exhaust temperature too low) False DTC P06EA (NOX sensor processor performance (bank 1, sensor 1) DTC P249C (SCR time to closed loop) - improved diagnostics and reporting DTC P249F (excessive time to enter closed loop DPF regeneration control) - improved diagnostics and reporting False DTC P0884 (PCM/TCM power input signal intermittent) DTC(s) and freeze frame data being erased in the PCM when running KOEO, KOER, Datalogger, Active Commands or any other guided diagnostics with IDS False P0731 (gear 1 incorrect ratio) False P0732 (gear 2 incorrect ratio) False P0733 (gear 3 incorrect ratio) False P0734 (gear 4 incorrect ratio) False P0735 (gear 5 incorrect ratio) False P0729 (gear 6 incorrect ratio) Low speed/load engine surge Abrupt engine shutdown feel HP fuel pump knocking noise at idle Delayed DEF level indication after refill event Harsh/bumpy transmission upshifts/downshifts Delayed/harsh transmission engagement feel between R-D and D-R shifts Transmission gear hunting during speed control operation when climbing grades or climbing hills, particularly while towing Erratic transmission operation after descending grades while in 1st gear Flashes/delays of current gear indication when using SelectShift mode Added Brake Over Accelerator (BOA) feature - reduces engine power during off-idle driving when both the accelerator and brake pedals are applied simultaneously Added SelectShift memory feature, so SelectShift gear display comes back on whenever going back into drive if the vehicle was turned off while SelectShift mode was still activated Added engine protection feature from overspeed while descending long grades while towing and in manual gear ranges (forces transmission upshifts at 4000 RPM) Increased torque - during hill assist operation - (see Owner Guide for additional system operation) PTO operational enhancements - (applicable to vehicles equipped with optional PTO) - Automatic secondary electronic idle controller (SEIC) turns on at engine start if the switch in on position - Engine coolant temperature to operate PTO lowered to -7 °C (+20 °F) - Improved RPM control with SEIC controllers WARRANTY STATUS: Eligible Under Provisions Of New Vehicle Limited Warranty Coverage And Emissions Warranty Coverage IMPORTANT: Warranty coverage limits/policies are not altered by a TSB. Warranty coverage limits are determined by the identified causal part. OPERATION DESCRIPTION TIME 110323A 2011 F-Super Duty 6.7L: Check DTCs, Reprogram The PCM And TCM (Do Not Use With Any Other Labor Operations) 0.6 Hr.
