data list.
Does the ATF temperature exceed the ambient-air
temperature?
YES—Record the ATF temperature. Leave the
engine off for more than 30 minutes, and go to step
2.
NO—Record the ATF temperature. Test the stall
speed RPM (see page 14-201) three times. G o t o
step 2 after stall speed testing.
2. Check the ATF temperature w i t h the HDS.
Does the ATF temperature change?
4. Check the ATF temperature w i t h the HDS.
Is the ATF temperature almost equal to the ECT
SENSOR (1)?
YES—Intermittent failure, the system is OK at this
t i m e . Check for poor connections or loose terminals
at the ATF temperature sensor and PCM. •

3. Check the ECT SENSOR (1) w i t h the HDS.
Is the ECT SENSOR (1) equal to the ambient-air
temperature?
YES—Go to step 4.
NO—Leave the engine off until the ECT sensor (1)
equals the ambient-air temperature, then go to step
