I was wondering if someone could clear something up for me about the scanguge Egr values? My truck will not read the EGR-EMV code. how ever It does read the EGR Value Desired and it is reading EVD 11@Idle with the EGR Throttle Position Desired reading ETP -4093 @Idle and only move up to -4096 when I rev the engine. Is this normal?

 

Ok guys I think im on to something here! I had the wrong codes for ETP Egr Throttle Position and the EGR EVM. Now got them workin and this is what I found. 11% EVD 3 ETP, 27%EGR @ hot Idle.

 

Bump for the night owls!
