Section 05 2–TEC ENGINE MANAGEMENT
Subsection 02 (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/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.
