1MZ–FE ENGINE – CHECK FOR INTERMITTENT PROBLEMS
VISUAL CHECK AND CONTACT
PRESSURE CHECK
(a) Disconnect the connectors at both ends.
(b) Check for rust or foreign material, etc. on the terminals of
the connectors.
(c) Check crimped portions for looseness or damage and
check if the terminals are secured in the lock position.
HINT: The terminals should not come out when pulled
lightly.
(d) Prepare a test male terminal and insert it in the female
terminal, then pull it out.
NOTICE: When testing a gold–plated female terminal,
always use a gold–plated male terminal.
HINT: When the test terminal is pulled out more easily
than others, there may be poor contact in that section.
CONNECTOR HANDLING
When inserting tester probes into a connector, insert them
from the rear of the connector. When necessary, use mini test
leads. For water resistant connectors which cannot be ac–
cessed from behind, take good care not to deform the connec–
tor terminals.
