P04DB00

2015 Dodge Dart Aero 1.4l w/turbo stock, no modifications

I wanted to get the wife to drive down to the 2016 meet up this past weekend but had no luck!!!
She’s had this problem with this car for a few weeks now and the dealership can’t seem to get it fixed. They ordered a part for it and never called her to let her know when it came in. She called the dealer last Saturday and they were supposed to call her back, that never happened. Then Monday she called again and they told her the part was in and ready to be installed. We went in today (Wednesday) as soon as the dealership was open and got the part installed (P/N 68217630AA sensor pressure). Drove down the road about a mile and went into a store, got what we went in for and when we came out, the engine lamp was illuminated again. Since we had to pass by the dealership to go home we stopped there again. Once again P04DB00 was the trouble code on their scanner. Got a ride home from the dealer and the vehicle is being checked out there again. Need a solution to this problem. Is there one???? I’ve checked everything I could find on line and there is no fix that I could find.

I don’t think you’re going to get any better information than the thread you started here:

Either the new sensor is DOA or the PCM isn’t outputting the proper signal or seeing the proper signal.

Honestly it’s a recorded issue at the dealer, the absolute worst thing you can do is start touching it. The second they see you’ve been in there, they are likely to wash their hands of it. Just work with them to solve the issue.

Remember, they are people too and they hold a lot of the power when it comes to making sure your repair is taken care of. Put what you need in simple unemotional terms and give them the opportunity to meet them. A huge majority of the time they are there to work with you and will gain nothing by not helping you.

Call corporate. Again, remember they are people too. They can often do things that the dealer can’t, or simply won’t do. If you need a rental, they can authorize it. Then if the dealer can’t solve it, there’s a definitive record of what’s been going on.

Agree…
It is the dealerships responsibility, let them correct the issue.
That is what a warranty is for. 😉

There’s not a whole lot of information on this vehicle, but I did manage to find some wiring diagrams at http://www.bbbind.com/tech_database.html
I downloaded all of them for the 2015 Dodge Dart Aero 1.4L Turbo
In the Wiring diagram section under Engine – Fuel Control System – Intake Air System, last rectangle on the top right (Sensor – Crankcase Pressure) of that section is what I think they replaced. The three wires match in color to the one in this schematic with a 5V reference, sensor signal and ground. I don’t have much faith in these techs at this dealership. Before I would replace that sensor I would have checked those 3 wires and checked the waveform of the sensor signal wire against a known good one. They replaced it and it didn’t fix the problem. They took out the K&N air filter that had been in it for 8,000 + miles and put a new Mopar filter in it and gave it back to her to drive yesterday. She drove it into work and when she started it up to come home, engine lamp illuminated again. As I type this she is on her way into the dealer again with her car. These newer vehicles are getting so complicated it’s hard to fix ’em anymore. I told her when she bought it she’d be getting to know the dealer and now I think they’ll be glad to get it fixed and not have to see her again (I hope). I don’t really want to work on it unless I really have to.

Update – The oil separator came to the dealer on Monday. They didn’t call, so my wife had to call. They couldn’t get it installed until Wednesday so she took it in first thing Wednesday and got it back that afternoon. Later that same afternoon we drove it about 5 miles to the mall. When we finished there and went to start the car the engine lamp stayed illuminated. Less than 25 miles were put on the vehicle and still the problem is there. She called the dealer first thing this morning and they told her not to bring it in yet. They wanted to talk to the engineers to see what to change next. Parts changers, not techs, no troubleshooting!!!!! So the vehicle is just sitting here now waiting to see what they want to change next. We’re supposed to be going to see my brother in northern MI on Saturday. I guess we’ll be driving it with the light on still, cause my Chevy C3500 dually with a 454 only gets 5 mpg and we’re not doing a 500+ mile trip in it!
Will keep this updated as it progresses.
