After replacing the corroded map sensor. The van now runs better than ever until I reach operating temperature and then the limp. Turning the key off resets it but it goes into limp immediately if the engine's warm. I now have added codes, P0045 Turbocharger boost control A circuit open, P0402, EGRA flow excessive detected, P0101, mass volume air flow sensor A circuit range performance Thanks in advance The internal piece of the old map sensor fell into the manifold during the swap!!!
