M: Pressure Transducer Main/Pri Input Circuit Fail

Pinpoint Test M: DTC C1288--Pressure Transducer Main/Primary Input Circuit Failure

Note: When diagnosing this DTC, the main/primary pressure transducer is the C147 pin 1, Circuit 9-CF64 (BN/YE). 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.
