VSV and EGR P0401
I am new to the forum-2001 I4 2.2 L 79K. I have searched and came up with the fact that most of the folks who have replaced the VSV have been able to clear the CEL. Well I did so after bench testing the old VSV-bad-then proceeded to run the tests on the EGR, the Modulator, and the MAP sensor. Everything checks out. Clear the code and back again-P0401.
I am going to research it more, though the circuit is so simple I can't figure to where the problem might be and to what I might have done improperly.
Inputs appreciated, thanks.
