LLY: EGR valve Need HELP

[mraaaooo]

Got DTC P0401, P0404, P1404
Replaced stepper motor but still get same codes

The most strange is that I get these errors only if engine is hot
On cold engine it does not set codes

Possible wire harness related. Did you disassemble and clean out the Valve while you were in there?
