KY ecodiesel issues

[W Royalty]

I purchased a 2015 Ram 1500 eco about a year ago with 42,000 mi. Soon after purchase service engine throttle red lighting bolt and limp mode! I have a very steep drive and this happened at top of hill turning out of drive. $378.00 and new map sensor and a couple of weeks later lighting bolt and limp mode. This time I reset the code myself and drove on with no issues. About 3 months later under same conditions it happened again and reset the code and still driving.

Now getting p24ae. Have onsite edge and getting acceptable soot level indications. I believe the sensor is bad. Have tried to take it out and see what condition it is in but can’t break it loose. Fuel mileage has been 22/23 short trips and 26/27 highway. Truck runs great now at 53,000 but cel won’t stay off.

I think the sensor is good. You need to once again clean the MAP sensor and then remove and clean the EGR diffuser tube. Then go for a ride on the highway for an hour. Clean it up quick before you have to pay for a dealership regen. I would suspect you also have a leaking EGR cooler. Check your truck coolant level and see if it is low. It may be leaking and causing you to soot up faster than expected.

Strongly recommend you get a GDE or PPEI engine tune to turn the EGR valve off.

Welcome to the site! We have folks here that can give you good input.

Thanks cs. I just watched a video on cleaning egr diffuser and see what you mean. I’ll get in garage this coming week and see what condition mine is in. Thanks again

please strongly consider getting the GDE tune so all these kinds of problems stop costing you trouble and money.

As expected here’s before and after. I am going to go for a GDE real soon. I have insight edge that lets me know when regen is taking place and I am still trying to decide if I want to add any options.

amazing! MAP sensor too?

Didn’t do map sensor. It was replaced recently. Probably should have but got sidetracked. Did drive through a regen. Soot level on Edge was @71% when started and dropped to 9% at complete. An appointment with a rod and reel kind of interrupted any other work on truck for today.

Just tried out GDE for first time. Wow! Chose the Regen option and took it through the first regen. Reset my trip a and monitored last 20 miles. Local driving, stop and go at least six times and major increase in mileage. I know this is not enough mileage to determine what results will be but they are better than I’ve ever gotten. Soot level dropped to 8% at completion of regen and only increased 2% in next 25 miles. This is probably 1/3 what I was seeing.

makes the truck so much better than factory. Taking the EGR out of the loop really fixes it, along with the other tune benefits.
