Section 06 ENGINE MANAGEMENT (4-TEC)
Subsection 03 (COMPONENT INSPECTION AND ADJUSTMENT)
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 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 generate a fault code.
