PINPOINT TEST P: DTC C1440-PRESSURE TRANSDUCER INPUT CIRCUIT FAILURE

Tests P1 - P5:

Test P6:

Normal Operation
The pressure transducer transforms brake fluid pressures in the master cylinder to an electrical signal which the ABS module receives through circuit 8-CF64 (WH/BK). The transducer receives a five-volt reference from the ABS module through circuit 7-CF64 (YE/BK). Circuit 9-CF64 (BN/YE) provides ground for the transducer.

Possible Causes
^ power circuit 7-CF64 (YE/BK)
^ ground circuit 9-CF64 (BN/YE)
^ transducer signal circuit 8-CF64 (WH/BK)
^ pressure transducer
^ ABS module

NOTE: Excessive clearance between brake pad and rotor, leaks, or air in the hydraulic brake system.
