Test N5 Continued:






NOTE: When diagnosing this DTC, the main/primary pressure transducer is the C148 pin 1, circuit 9-CF65 (BN/WH). The pressure transducer connectors can be connected to either the main or the redundant pressure transducer and still operate correctly, therefore the wire color must be looked at before continuing diagnostics.
