I still have the P0299 - so my tune isn't blocking anything. I am pressure/smoke testing the exhaust today to see if there is a boost leak or any leaks in the downstream components. I ran the actuator yesterday from AlphaOBD and it moved perfectly, so either the turbo is plugged up or on the...

Hi everyone! I detled my 2016 1500. Everything is fine until I started chasing an underboost issue (P0299). Using TopDon scanner tools I noticed that the VGT position called for and actual were very different and the airflow the engine should be getting is about 1/3 of whats called for. I have...

...have learned a TON here from Googling and ChatGPTing my way to this forum. Deleted 2016 1500 Big Horn Crew - Everything went well until the P0299 LMFBO! RABBIT HOLE! So I have embraced learned code readers and have lived under my truck for a week and half. Smoke test. Pressure test. Then...

2016 Ram 1500 Ecodiesel 67,000 miles Service Electric Throttle Control P0299 - Turbocharger Underboost P0401 - Egr Flow Insufficient Detected While I was driving on the freeway yesterday I got a message on my dash telling me to service the electric throttle control. The check engine light...

P0299 and another one I can’t remember. Like a p0238 I forget. I’m not in my truck anymore part. Mainly the P0299 everytime

Also when I first fire the truck up it sounds like it’s surging in the air box you can feel it when you put your hand on it sucking hard then stops like it’s taking deep fast breaths almost . Felt it in my intercooler tube also it’s loud enough to hear it surging in and out …..

...that has something to do with it ? Also drove it it wouldn’t accelerate then bam Rpms fly up and truck takes off then sluggish again won’t go p0299 code thrown turbo under boost also when it does take off fast outta nowhere I can’t hear the turbo anymore ? Can anybody help me where to look ...

...reads *edit* 52-54 psi. But when it cranks the psi drops to about 40-46 psi. Do you or anyone know if this is normal? Should I replace my lift pump? I have no codes besides p0299 which is caused by exhaust leak after doing an EGR/DPF delete and tune. Any help will be much appreciated! Thanks!

...yesterday driving to work. Engine starts stumbling and bucking. Then power drops severely. Running the codes I get the above mentioned u1424 p0299 p0234, and I am looking at 1 psi of boost max. I limp in to work, take a look to make sure I did not blow an intercooler pipe (just installed...

Hello I have a 2016 eco diesel with km175 and a delete done two just recently I keep getting the po299 code only when I tow i used to get it when I didn’t tow two I changed the map sensor the air filter gas filter and cleaned the mass air flow sensor it stopped doing it when I don’t tow but...

...diagnosed a bad throttle actuator. I also had to wait 3 weeks for the parts to come in so I kept driving it and resetting the codes (P02E8 and P0299). However, if you do keep doing that, it won’t run a DPF regen due to the active codes. If it doesn’t regen, it will eventually become dead in...

The hissing noise would have me looking for air leaks in the pipes/hoses that run from the turbo to intake first. Especially clamped areas, in case a clamp has came loose.

Hey guys I’m new here I have the dreaded p0299 turbo underboost code and it’s driving me mental ill clear it and it’ll be fine for 10-15km or so then comes back on I can see on my boost gauge I’m only hitting 18-19psi or so and can hear a hissing noise coming from the engine bay I can’t for the...

...The check engine light went off on its own the next day. I thought it may have been dirty fuel or something. Now I have recurring P0402 and P0299 codes and a service electronic throttle control light that comes on quite often. I just got it back from my most recent trip to the dealer where...

...tunes no deletes. Kept up on regular maintenance, oil changes, filter changes without issue. Over this past winter I have had codes P0402 and P0299 pop up and can’t shake them. I’ve cleaned my MAP sensor and EGR Diffuser tube and the codes are still there. The tube and MAP sensor were fairly...

...starting, took two tries but sounds perfect now that it's running. Tried to reset the CEL and it won't clear. CEL said P0208, P0336, U1401, P0299. Took it for a spin about 5 miles out, limp mode and all. Reset the CEL at the grocery store parking lot. Won't clear. Get home, now P0299...

...blowing white smoke and had no turbo. Thankfully I was at the top of the pass and was able to coast it down to a gas station. I got the code p0299 I believe, the turbo underboost. I shut it off and retuned it back to stock (I have the mr tuning tune)to see if that would work. Thank goodness...

...throttle body and the truck went into limp mode. Cleaned the EGR tube and map sensor and all was good. Drove to town this weekend and got the P0299 code again but didn’t get the clean throttle body msg and truck didn’t go into limp mode. Reset the code to it out and hammered down on...

Wow, P0299 is for Turbo Under Boost, which will set the Service Electronic Throttle Control message, I fail to see how the EGR cooler would affect that, but since there was and active recall for that system it doesn't hurt. Now the P245B is related to low voltage in the EGR Cooler circuit which...

The Egr is leaking into your oil. Don't drive it. The egr is under extended warranty.
