The resistance value of a temperature sensor may
test good at a certain temperature but it might be
defective at other temperatures. If in doubt, try a
new sensor.
Also remember this validates the operation of the
sensor at room temperature. It does not validate
the over temperature functionality. To test it, the
sensor could be removed from the engine/air si-
lencer and heated with a heat gun while it is still
connected to the harness to see if the ECM will
detect the high temperature condition and gener-
ate a fault code.

ECM Connectors
The most recommended and safest method to
probe ECM connector terminals is to use the
ECM adapter (P/N 420 277 010). This tool will
prevent deforming or enlarging terminals which
would lead to bad ECM terminal contact creating
intermittent or permanent problems.
420 277 010
Disconnect the desired connector from ECM and
reconnect on the tool connector. Probe required
terminals directly in the tool holes.
