Turn the ignition off.
Reconnect all the sensors that were disconnected in the previous step
except the CMP Sensor harness connector.
CAUTION: Do not probe the PCM harness connectors. Probing the
PCM harness connectors will damage the PCM terminals resulting
in poor terminal to pin connection. Install Miller Special Tool #8815
to perform diagnosis.
Measure the resistance in the (F856) Auxiliary 5-volt Supply circuit from
the Sensor harness connector to the appropriate terminal of special tool
#8815.
It may be necessary to perform this test from every sensor that uses
the (F856) Auxiliary 5-volt Supply circuit.
Is the resistance below 5.0 ohms?
