I have a 2017 Ram 1500 EcoDiesel. In mid-April I got the Service Electronic Throttle Control message with the DTC P0299 (77,000 miles). After some research I decided to try cleaning the soot out of the MAP and sensor then clear the code. Service Electronic Throttle Control message with the DTC P0299 was back within a few weeks. I took it to 3 dealerships in the Fort Worth area before one had a diesel tech on staff (crazy right?). By this time, it was early June. That dealership determined the solution was to replace the EGR Cooler. They did that under warranty and had it back to me after a couple weeks. On my way home from the dealership the check engine light came on- this time P245B. I took it back a couple days later (early July). It took them 3 weeks of testing and communicating with Chrysler to decide that the solution is to replace the exhaust temperature sensor ($520). I called Ram Customer Care to explain what is going on and see if there is anyway this is under warranty. They basically just asked the dealership if they thought it was related to the previous problem. The dealer said they didn’t think it was so Ram Care told me there was nothing they could do. I paid the $520 and got the sensor replaced. I drove the truck for a few weeks locally and on some longer trips with no issues. Then I drove the truck 2,000 miles on a trip, still no issues. The day after my trip (80,000 miles), I started my truck and got a P2D2F code. I took it to a fourth, different dealership in a more rural area hoping they had technicians that were more familiar with diesel engines. They quickly diagnosed that the issue was that the cylinder 5 injector is over fueling and the cylinder 4 injector is under fueling. They came to this conclusion after a “manual fuel system test” and the solution would be to replace all the injectors and lines for $2,900. I am going to reach back out to Chrysler but hopefully someone on here has some advice.
