GAS TEMP test point
EVAP TEMP test point
1.
When measuring DC voltage, use Evap Temp and Gas Temp points
to GND (ground) test point.
2.
When measuring DC voltage, measure from ET Sensor pin to pin
and GT Sensor pin to pin at J3 connector.
3.
When measuring resistance, remove J3 harness and measure ET
and GT pin to pin
