Check Engine Light came on today. Car idles fine. Came up with 2-4-1 on the ignition side of the OBD. No temperature sensor that I can see in the EGR line up to the manifold. There is 12V at the connector. EGR vacuum booster checks in at 65Ω. Bentley claims the spec is 85Ω +/- 10.

Since the booster is the only electrical part in the EGR system, I suspect that it is triggering the CEL. Has any one hacked the EGR system to eliminate / substitute / repair the vacuum booster and keep the EGR system working ?

Thanks

Greg
