To much additive

[chopper698]

I have been using power service fuel additive in my 2011 6.7 all winter and still up until last week, only cause I want to finish eats left. Now 2 weeks ago my engine light comes on and through my edge insight I checked the code PO14C which was slow response rich lean condition. I cleared the code through my insight only to have it come back a day later. I brought it to the dealer and was told your tuner was setting off codes. I said what tuner? Those are just gauges you can't tune or change any parameters with that. They said there technician said when they unplug the so called tuner the light goes off and there is a lot of power when its plugged in. I said you better send your tech for a drug test. I called edge products they said its impossible to program anything through that there just looking for anything to put the blame on other than there product especially warranty work. But my theory is I think I was using to much additive and which was causing that engine light and 02 sensor to react because of the amount of cetane. I also noticed that my truck was regening everyday. Any thoughts on this?

I'll look into this tonight and see if I can find something on this.

[chopper698]

Thanks I appreciate it. The dealership also said if it comes back with those codes and the edge insight installed they are voidin my warranty. Nice bunch of people.

Apparently they haven't heard about the Magnuson-Moss Act. The Wikipedia article is more of a general description:

Part 1:

P014C-O2 SENSOR 1/1 SLOW RESPONSE - RICH TO LEAN

Theory of Operation

The engine aftertreatment system monitors the oxygen content in the diesel engine exhaust. The Powertrain Control Module (PCM) monitors the exhaust gases for oxygen content and varies the rich/lean fuel mixture of the intake air fuel mixture to adjust the system. This diagnostic monitors the status message broadcast by the Smart O2 sensor module for the upstream O2 sensor circuit. The PCM will set the fault if it receives an FMI (Failure Mode Indicator) message from the Smart O2 Module. The PCM will illuminate the MIL lamp immediately when the diagnostic runs and fails. The PCM will turn off the MIL lamp diagnostic runs and passes in four consecutive drive cycles.

When Monitored: This diagnostic runs when the engine is running.
Set Condition: The Powertrain Control Module (PCM) will set the fault if the O2 Sensor 1/1 responds too slowly.

Possible Causes
EXCESSIVE FUEL ENTERING THE AFTERTREATMENT/EXHAUST SYSTEM
MASS AIR FLOW SENSOR
ENGINE MISFIRE
FUEL DELIVERY SYSTEM FAILURE
INTAKE AIR SYSTEM LEAK
EXHAUST SYSTEM LEAK
EGR SYSTEM LEAK
O2 SENSOR 1/1
O2 SENSOR MODULE
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).

NOTE: Before replacing O2 Sensor or O2 Sensor Module, check aftertreatment wiring harness for spread terminals. For wiring harness checking procedure, DO NOT back probe, use Electric Terminal Tool Kit 8197A (http://millerspecialtools.spx.com/Detail.aspx?id=375) ( 6801 (http://millerspecialtools.spx.com/Detail.aspx?id=1663) Tool).

1. ACTIVE DTC
NOTE: If there are any cylinder misfire, Crank Sensor, MAF Sensor, or Fuel Injector DTCs stored with this fault, perform the diagnostics for those DTCs before proceding with this test.
1.Turn the ignition on.
2.With the scan tool, record all Freeze frame data.
3.With the scan tool, erase DTCs.
4.Turn the ignition off for 75 seconds.
5.Start the engine and let idle up to five minutes.
6.With the scan tool, read DTCs.

The fuel delivery system test in step 2 is a long procedure that involves checking a variety of components/items. Fuel pressure, fuel condition, leaks, flow, etc. Because extra fuel is injected on the exhaust stroke for DPF operation they want to make sure it is operating properly.

The intake air system pressure test is basically checking the intercooler and intake piping for a leak.

The exhaust system leak test is self-explanitory, it is tested in a similar fashion as the intake air system.

If the DTC resets without the Edge Insight plugged in then they have to go through the diagnosis.

The excessive regens is possibly caused from the O2 not reading right.

[chopper698]

So is or was there a defective 02 sensor or was it just sooted up? And in your opinion did the edge have any effect on this? And thanks for the whole breakdown on the PO14C, I have been on numerous forums and couldn't get an answer or even a suggestion on that code.

I highly doubt the Edge Insight had any effect, but anything is possible. As far as the Upstream O2 sensor, you'd have to go through the diagnosis as directed from step 6 on. If after cleaning both sensors, clearing the codes and running the truck 5 minutes the DTC resets you then switch them with each other, clear the codes again then run the truck another 5 minutes. Code switches to Downstream sensor code listed, bad sensor. Same code, bad O2 sensor module.

[chopper698]

Tbird where are the 02 sensors located? And are they easy to pull out and clean? I was reading on another thread to leave the EB on and use the +/- and keep it out of 6 around town and to not lug it and keep rpm's upto 1500. It's tough cause my round trip to work is 35 miles, going there is all highway coming home is highway but sometimes it crawls. And I don't pull a trailer but I do haul wood and coal and occasional motorcycle or two.

the over fueled condition from the edge prog is cloging your dpf( reason for the daily regen) emissons system is sensing the cetane booster also...this was only noticed when out side air temp rose and the intake charge became less dense....

[chopper698]

How is it being overfueled by the edge, its not a tuner or programmer. It's just an extra set of gauges, and a maintenance reminder.

[Tbird100636]

1 is Upstream, 2 is Downstream.

According to Chrysler as little as 45 minutes of highway driving is needed. If you have time on a weekend take a trip down the highway. Do more than 45 minutes just to be sure it fully regens. Shouldn't matter wether the exhaust brake is on or off or what gear it's in.

[chopper698]

Thanks for the diagram, can these be taken out cleaned?

[Tbird100636]

Thanks for the diagram, can these be taken out cleaned?
Yes they can.

[chopper698]

Thanks Tbird, I have started keeping the EB on all the time now and when not on the highway keep it in 4th and 5th to keep the rpm's up around town. Im gonna keep the edge unplugged for now and use up that tank of fuel that has the additive in it and see what happens.
