EGR fault code in a '97

Post by GeekWarrior77 »

Got a CEL on the highway. Pulled code P1418 - EGR temperature sensor signal. The car is an 1997 850 t5. From my understanding there is no EGR in 97's.

Earlier this week I installed an ARD TCV and swapped in an ARD "Stock R" ECU. Could the swapped ECU be from a EGR car thus causing the CEL? Oddly the CEL lit the moment I clicked on the A/C for the first time in a while. Thanks.
