Deleted 2014 ecodiesel, service electronic throttle control light on. No check engine light.

[Ecodiesel_dave]

I have a 2014 eco diesel that’s deleted. The service electronic throttle light came on with no check engine light. When I monitor the EGT 1 sensor it’s reading 32 degrees consistently either parked or driving, measured the resistance of the temp sensor and it’s at 257 K ohms. (Sensor looks new)
When you clear the nonexistent trouble codes the light goes out and stays out for a few hours worth of driving. I’m thinking it’s to do with the tune as all the other EGT sensors read the same(32)even though they aren’t there. Anyone see something like this before?

Do you have an EGR delete?

My egt 1 always reads correctly, 2-3-4 always are a consistent readout but it’s like -600f or something lol that sensor is like 300$+. I have a new one that’s reading 216.6 at 60ish degrees.

I should add this sensor goes on passenger side rear part of the manifold pre turbo

Had the same issue recently. Full Delete if egr and dpf done in january. I thought many of the sensors would have been bypassed by the tune but not this one. New pre turbo sensor installed and back on the road. Lost all 4-8 gear acceleration without that sensor working. Question, anyone know if it is that a safety thing or prevention thing?

Yes thank you. I have actually had this sensor replaced and air intake cleaned twice and tested for leaks now with none found and there is still build of soot triggering the sensor and setting off the throttle control light.
Anything you suggest in this case?

 

[Tremper126]

You still have soot buildup in the intake?

It looks like that yes. Is it because the egr cooler may have left some or it wasn’t cleaned out enough?

 

[Tremper126]

If you have had the intake cleaned twice it seems your egr is still allowing soot in it. Do you still have the tube going into your intake?

 

[Taxpayersmoney]

The egr is removed and there is just a bypass tube i believe for coolant. But i recently took out the intercooler tubes and plugged them and the exhaust tailpipes and intake and i pressurized it. I think i discovered the gasket in the push-on intercooler tubes were not see right and it seemed to hold pressure. I erased the codes and it seems all good now.
Did see some oily liquid inside the tubes that I wiped out. Is that an inticator?

 

[Tremper126]

The crank case vent dumps back into the intake tube before the turbo, so I would venture to say the tube leak was the culprit! Mine has some slop near the turbo outlet

 

[Taxpayersmoney]

Oh yes thanks for reminding me, so it will never be clean but egr delete should reduce the soot? . I heard it called a waste gate on a youtube video. Is there a way to tell if those are jammed open? I read that that is somewhat common.

 

[Tremper126]

We don’t have wastegates as our turbos are vgt meaning they have vanes inside that open and close to control boost. Your intake shouldn’t get anymore soot than what is there now at this time since the egr is no longer recircing exhaust gasses back to the intake. Now, the oil residue will continue in your intercooler piping unless you install a catch can, but they can create their own set of issues with the check engine light. To me, the little oil present that it causes isn’t ideal, but it’s not worth me worrying over. An overabundance of oil use in the future and no oblivious leaks can mean the turbo seals have failed internally and that will cause much higher oil concentrations in the intercooler piping but I don’t think I’ve seen anyone have that issue on here. I have seen reports of stuck vanes causing under and overboost conditions
