Hello and welcome to JustAnswer!I'm not showing this to be a valid code for the vehicle listed. It's possible that it was just a typo or if it was read with a generic scan tool or code reader then it may have been reported wrong. Once ina while an engine controller will fail and set codes that it shouldn't be capable of but it's not common.Can you double check the code?
Customer: replied 6 months ago.
I know the discription of the code is
Low pressure egr controller implausible
I have replaced the low pressure egr
Valve already.The code comes back
On second key cycle.
Another code that comes after the first code is low pressure egr cooler

Expert:  sprinkles08 replied 6 months ago.
The definition of 4C87 is EGR cooler efficiency low, 4779 also does not show valid. Did you replace the actual EGR valve or did you replace the cooler?

Expert:  sprinkles08 replied 6 months ago.
The cooler is the cause of the 4C87, cooler efficiency is the definition of the code and the only possible causes are the cooler and the EGR Valve 4779 is not valid per factory service information.4C87 is the same as P14D0, which I believe you meant to type when posting the question but there was a typo.

Expert:  sprinkles08 replied 6 months ago.
Alldata is factory service information. Based on the information known about the code that is valid, I would recommend replacing the EGR cooler.
