Driverj Posted December 28, 2010 Share Posted December 28, 2010 In the last month I have seen 5 trucks with code P164A, all diag tests show no faults, hotline guidence is also a let down We have tried a new module and sensor with no change, after the road test the code comes back,and later the light comes on. I'm really not sure what step to take at the moment. any sugestions Quote Link to comment Share on other sites More sharing options...
GregH Posted December 28, 2010 Share Posted December 28, 2010 Are you at the latest calibration? Quote Link to comment Share on other sites More sharing options...
Gofaster23 Posted December 29, 2010 Share Posted December 29, 2010 You have to drive the vehicle for a minimum of 25 miles for the DTC to clear. Don't worry, it dosen't tell you that in the PCED, workshop manual, SSM, or TSB. Clear all DTC's, drive for over 25 miles, said DTC should be gone. Been there, done that.

Jeff_E Posted December 31, 2010 Share Posted December 31, 2010 Well guys, I have one in right now for this code. PPT leads to a NOx sensor, but our parts guy can't seem to find it. Anyone know the part number for a NOx sensor??? Quote Link to comment Share on other sites More sharing options...
Gofaster23 Posted December 31, 2010 Share Posted December 31, 2010 BC3Z-9D378-E as per TSB# 10-19-7. Quote Link to comment Share on other sites More sharing options...
Jeff_E Posted December 31, 2010 Share Posted December 31, 2010 Thank you sir! I even used Oasis quick start and it didn't show that tsb for my code Quote Link to comment Share on other sites More sharing options...
Jim Warman Posted January 1, 2011 Share Posted January 1, 2011 Thank you sir! I even used Oasis quick start and it didn't show that tsb for my code Your code (P164A) doesn't relate to that TSB... neither does the one that will soon join it (P2A00). You will find that the part is updated (new part number) and our partsmonger cannot give me a delivery date. We are seeing a lot of these....

Jeff_E Posted January 1, 2011 Share Posted January 1, 2011 Excellent... More labor ops for me It's too bad I actually went through all the motions. It sounds like this may be the 6.7's equivalent of the DPFE if you know what I mean. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted January 1, 2011 Share Posted January 1, 2011 It sounds like this may be the 6.7's equivalant of the DPFE if you know what I mean. Oh no you didn't! You did not just say that!!! Quote Link to comment Share on other sites More sharing options...

Jim Warman Posted January 1, 2011 Share Posted January 1, 2011 Have you read through PPT RD? What I get out of the tree for P164A - if the NOX module has power and ground, replace the sensor. Now.... if you replace the sensor because of a P207F, you do one thing... If you replaced the sensor because of any other codes, you do something different. I'm sure there is some logic there... but it escapes me... FWIW.... you need to read RD10 very carefully because it was written so poorly.... Sidebar... Even Ford has fallen into that trap where they can't reconcile "then" and "than". Please, guys.... "I would rather buy him lunch <than> give him a blow job" reads a LOT different from "I would rather buy him lunch <then> give him a blow job".... Just sayin'.....

Keith Browning Posted January 19, 2011 Share Posted January 19, 2011 BROADCAST MESSAGES 1/19/2011 2818 - 6.7L DIESEL - MIL DTC(S) P164A AND/OR P2A00 - ENGINEERING INVESTIGATION SOME 6.7L DIESEL EQUIPPED VEHICLES MAY EXHIBIT MALFUNCTION INDICATOR LAMP (MIL) ILLUMINATION AND DTC(S) P164A AND/OR P2A00 BEING STORED. THIS MAY BE MORE COMMON IN AREAS EXPERIENCING VERY LOW AMBIENT TEMPERATURES OR HEAVY SNOW FALLS. INSPECT THE AIR FILTER MINDER FOR RESTRICTION INDICATION AND REPAIR AS NECESSARY. IF NO OTHER DTC'S ARE SET AND NO DRIVEABILITY CONCERNS ARE PRESENT, PERFORM NORMAL DIAGNOSTICS. IF DIAGNOSTICS LEAD TO NOX SENSOR REPLACEMENT, DO NOT REPLACE THE NOX SENSOR AT THIS TIME. IF ADDITIONAL DTC'S ARE STORED, PERFORM NORMAL DIAGNOSTICS AND REPAIR AS DIRECTED. ENGINEERING IS AWARE OF THE CONCERN FOR MIL DTC'S P164A AND/OR P2A00 AND CURRENTLY WORKING ON A CALIBRATION UPDATE.

64nomore Posted February 24, 2011 Share Posted February 24, 2011 Have first 6.7 in bay now. Codes P012f, p0133, p164a, p2a00 koeo, passes koer. p012f and p0133 ppt states diag other codes first, ssm to 21690 states under investigation. So do i disregard p012f and p0133 too. will contact hotline Quote Link to comment Share on other sites More sharing options...

mchan68 Posted April 18, 2011 Share Posted April 18, 2011 Well folks. I have my first one here with P164a set and went through PPT RD up to step RD10. No later calibration available as of yet (my IDS is up to version 72.02). The problem with this one, it operates in engine idle only mode, so we can't release it back to the customer.

lmorris Posted April 18, 2011 Share Posted April 18, 2011 Odd that it's in idle only. We have a lot here and all they do is reduce power while the light is on. Are you sure it's not out of DEF or the sensor thinks it is? Quote Link to comment Share on other sites More sharing options...

Are you sure it's not out of DEF or the sensor thinks it is?Well, two Hotline engineers are stumped with this one, as am I. Both as well as one of my "go to" guys have also informed me that a P164a by itself SHOULD NOT put this vehicle into "idle only" mode. And yes, I've already checked the DEF level and verified the vehicle has the latest calibration update (as of IDS version 72.02). According to the customer, he states that vehicle will accelerate from a stop and feel like it's in neutral, meaning engine speed will increase with throttle response, but no increase in vehicle speed.

mchan68 Posted April 20, 2011 Share Posted April 20, 2011 Well, the FSE is now involved with the one I'm working on. I've been informed that the new calibration is to be released at latest by the end of the week, if not by tomorrow. In the mean time, I've been instructed to replace the NOx sensor (despite PPT RD10 checking out good). What now concerns them, is the loss of accelerator control of engine that has happened twice with this truck since it showed up on our doorstep yesterday morning. We've also been instructed NOT to release the vehicle back to the customer, and I've been instructed to drive it home until I can recreate the symptom again with IDS connected to take a "snapshot" of all the PIDs. When it occured yesterday, I noticed APP 1, APP D and APP E all showed a change during full sweep of the throttle, but APP 2 remained at 0.41 volts. Shutting the engine down and restarting it about three times was all it took to restore accelerator control of engine speed (along with APP 2 to read again). It did this TWICE with only P164a set. Apparently mine is only the fourth such reported case of this happening. The "brake over accelerator" feature is BS by the way, because I attempted it today, with the FSE riding shotgun and IDS in his lap. Quote Link to comment Share on other sites More sharing options...
