moving connectors and wiring harnesses related to the
sensor.
A change in the display will indicate the location of
the fault. If DTC P1515 cannot be duplicated, the
information included in the Failure Records data can
be useful in determing vehicle mileage since the
DTC was last set.
If it is determined that the DTC occurs intermittently,
performing the DTC P1515 Diagnostic Chart may
isolate the cause of the fault.
