P164A is back again

I got the P164A code again. Dealer will not even evaluate the situation or reset the code. They told me Ford told all service techs not to touch it until they have a fix and the fix was suppose to be last month (mid-Fed).

This time I was going up a small hill at about 45MPH, truck sputtered for ~20 seconds and just about died, then the "Cleaning Exhaust Filter" message came up and the truck started to run fine. Shortly after, the CEL showed up.

Frustrating...

My dealer tells me that Ford has the fix but is waiting on EPA approval. I asked him how EPA approval effects vehicles in Canada and he didn't know...
If Ford is in fact waiting for EPA approval who knows how long it will be. My CEL has been on since November. Way too long already in my opinion.

I second the Frustrating....

What I find frustrating...and I know I'm stating the obvious...but how would I know I didn't have other codes on top of it if we didn't have a code reader? We have 4x 2011's in our fleet and 3 of them all have this code. Come on Ford or EPA or whomever!

Fix is in!

So I had my truck in getting it's first oil change and the fix arrived so they actually got it on mine first! It was a reflash of the computer so not sure exactly what it does (maybe just ignores that sensor now), but it's on there now so hopefully that's that!

That's good news! If anyone locates the TSB can you please post it. I will have to take it to my dealer for them to know what I am talking about.

Thanks

I think this is the TSB that fixes the CEL.
Copied from another forum

NEW TSB (11-3-23) FOR CEL AND SHIFT ISSUES
________________________________________
Hope this is the one that finally fixed the shift issues....

FORD: 2011 F-250, F-350, F-450, F-550


This 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
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

Sorry guys, I just brought this TSB to my dealer and they tell me Ford has pulled this TSB because of some shifting issues it causes.....

So we sit and wait AGAIN, I have really had it with this issue AND the way it has been dealt with.

Dealership called me and they are 'recalling the recall'.

Oh and my CEL is back on and the truck is running worse now....

FYI for anyone who drives in a lot of snow and extended cold weather.

My dealer got me in a couple of days ago and they tell me the reason for the check engine light and P164A code (apparently there were other NOX sensor related codes there that I could not see with me cheap OBD-II tool as well) is that the air filter was plugged with snow. They say the reason it took so long to get in is because they have had over a dozen 2011's back with the same issue since we had our last big snow fall last week. My tech checked with another local dealer and same thing, the 2011's are lined up to get in. My dealer figures Ford will come out with a tech bulletin pretty soon (but who know's, that's just what he tells me) to fix this issue. He says it is an extremely high percentage here (Edmonton, Alberta, Canada) of 2011's that have come back since the last big snowfall / cold spell with this issue.

Dealer replaced the soggy air filer N/C.

For now I will install a winter front and see if Ford does anything.

And YES, I do know that the manual says to watch out for this...but there is no way I am going out every mourning in -20 to -40C and checking if there is snow in my air filter. I have been driving for 25 years and have never had to do it, no way I will start now. She will be sold if the winter front or Ford doesn't fix the problem.

But I STILL love this truck!!!!

Thanks
I have a 2011 f350 , just got code, middle of summer, 80deg. air filter is good.

Damm even I am having a similar kind of issue, I have searched all over the internet and even have posted on number of threads on different forum, no solution seems to work. I am really frustrated, can anyone of you here help me resolve this issue, I am very much tired now.
