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.
