Hello, about to service and fix other details in this 458 and while we scanned the car with an Autel scanner, got a complete report of DTC and in the slave ECU we got an active DTC, P5121. Car has no check engine light ON, but seems this is an ACTIVE dtc and says it's related to the stuck or open circuit for the control falp of the intake. I'm trying to locate the list of DTC's for Ferrari or for this particular model but can't find it anywhere. I have a copy of the workshop manual and can't find the lisf of DTC's as well. In this link appears to be a slightly different description for the P5121 if the check engine is not ON....anyways, if someone knows something about this particular DTC, let me know anything Ineed to check before start looking for the circuit components. Thanks!
