Unusual Failed EGRVP Response Pattern

[mchan68]

Just curious, but has anyone else ever had a 6.0L with a failed air management test where the EGRVP pattern looked something like this? Replacing the EGR valve repaired it, but this one didn't look dirty nor did the intake passages look like it was carboned up, which is unsual for an E-Series.

EGR Valve position sensor failure. I see it from time to time and have several screenshots.

Mike... press <print screen>, open MSPaint (or anything better you might have on that IDS) and click <paste> and save as "jpeg". The glare makes it hard to see.

 

Don't forget that the PCM isn't just looking at valve response through the sensor - it is also looking for coherent (as in within the expected range) sensor readings.

Seen it so many times I cant even come up with a number to give you.
