CIRCUIT INSPECTION
INSPECTION AT ECM CONNECTOR
• Always clean around and keep any foreign material away from the
ECM 33P connector before disconnecting it.
• A faulty PGM-FI system is often related to poorly connected or cor-
roded terminals. Check those connections before proceeding.
• In testing at ECM 33P connector (wire harness side) terminal,
always use the test probe. Insert the test probe into the connector
terminal, then attach the digital multimeter probe to the test probe.
