Which plug did you disconnect? If you disconnected the EBP Sensor (3 wires) that will disable the EBPV but the CEL light will come on. If you disconnected the 2 wire plug just below the turbo that also disables the EBPV, PCM will store a code but the CEL should not come on. If you have a Cali truck the CEL might still come on with the 2 wire connector disconnected .. I don't know.

well for a guess, you are right on the money. It is a California tr5uck and i did disconnect the two wire plug. I am wondering if i can place resistor in the plug so it can trick the computer?

I've never tried it but don't think it would work. If it was me I would unplug the IAT (intake air temp) sensor and stick a 37K ohm resistor across the two wires. PCM will think air temp is about 68 degrees and should not activate the EBPV except on engine start up diagnostic. IAT sensor is only used to control the EBPV (cold mornings) and has no other effect on engine fueling or performance.
