So I have a 2016 ecodiesel showing a p0402 code and a “service electronic throttle control” message I have replaced the egr cooler and valve, cleaned the egr diffuser, and replaced the map sensor. Any ideas what else could be causing these codes?
I will try that. 2015, 199K, setc, P0402 and P0183. Cleaned MAP twice, MAF twice, EGR tube twice and def nozzle once. Changed air and fuel filters. With codes cleared, it will idle rough until warmed up. No codes except low idle code. Still no pedal. After a few more minutes the pedal starts to work if pressed slowly until stops at 2700 rpm. Will not move. Still no codes. After a few more minutes the setc sets. Pedal is very responsive then up to. 2700 rpm. Will barely crawl. Usually code p0402 sets then and occasionally p0183. If I rev engine up, I will start seeing yellowish/brown smoke coming from tailpipes. ECM was updated Jun 2019 and EGR cooler replaced later. I will try BTdriver's suggestion in a day or 2. Trying to get the Jaguar inspected in case the ED does not get fixed soon. Any other suggestions will be appreciated.Just a guess here but check the throttle butterfly on the front of the intake manifold. If it's not opening up properly, restricting flow of fresh air, that will cause a greater draw from the EGR. Also, check the electrical connectors to it.

SomeoneYou also may have to check the DPF Pressure Sensor. I just returned one as that was my next piece of the puzzle but the EGR valve was my issue.
Are you referencing the flapper valve at the back of the EGR cooler? If so,, what was wrong with it? TY.You also may have to check the DPF Pressure Sensor. I just returned one as that was my next piece of the puzzle but the EGR valve was my issue.
Mine was fine but it was part of the exploration to get my truck running and clear codes. Make sure the line has suction going into the solenoid (flapper) on the back of the EGR cooler. Also test the plunger on the back side with the lever to make sure it moves freely. If that is failing and the suction fails to pull the flapper it could throw the code as the computer is telling to allow exhaust gas into the intake manifold. The DPF Pressure Sensor is under the truck and has 2 hoses to measure upstream and downstream flows. If one of the lines clogs or the sensor gets damaged it can no longer report to the ECU and puts the truck in limp mode.Are you referencing the flapper valve at the back of the EGR cooler?

mine gave me that code at 20000 miles, changed air filter and cleared and all goodSo I have a 2016 ecodiesel showing a p0402 code and a “service electronic throttle control” message I have replaced the egr cooler and valve, cleaned the egr diffuser, and replaced the map sensor.
