feed.
Diagnostic Aids
An intermittent may be caused by the following:
B Poor connections.
B Mis routed harness.
B Rubbed through wire insulation.
B Broken wire inside the insulation.
Check for the following conditions:
B Poor connection at PCM-Inspect harness connectors
for backed out terminals, improper mating, broken
locks, improperly formed or damaged terminals, and
poor terminal to wire connection.
B Damaged harness-Inspect the wiring harness for
damage. If the harness appears to be OK, observe the
cruise cancel switch display on the Tech 2 while
moving connectors and wiring harnesses related to the
sensor.
A change in the display will indicate the location of
the fault. If DTC P0566 cannot be duplicated, the
information included in the Failure Records data can
be useful in determined vehicle mileage since the
DTC was last set.
If it is determined that the DTC occurs intermittently,
performing the DTCP0566 Diagnostic Chart may
isolate the cause of the fault.
