Egr and vss code

[mclark]

Is there any solution to solve egr code. Cleaned egr port and replaced egr valve and egr solenoid vacuum.still have cel with codes.how to check ecm/pcm.

the egr code is typically due to the passages in the little steel lines that run from the egr tube to the sensor getting clogged up. cleaning the port is not the solution - cleaning those steel lines is the solution.
