So let me understand this correctly. You want to remove AIR pump, but you want to keep EGR valve??? Right ?

If this the case the EGR system uses EGR control valve which is mounted on a bracket bolted to intake manifold on the passenger side. ECM is uses PWM control signal to control amount of vacuum that reaches EGR valve. You can simply remove plug used to control AIR pump and individually tape of wire ends



On this bracket you'll find MAP, ESC module and EGR control valve. On the photo the EGR control valve is mounted on the backside, upper middle of the bracket (you can see white and pink wires protruding).
