DTC P0710: Problem in ATF Temperature
Sensor Circuit
NOTE:
• Record all freeze data and review General
Troubleshooting Information (see page 14-247)
before you troubleshoot.
• This code is caused by an electrical circuit problem
and cannot be caused by a mechanical problem in the
transmission.
1. Check whether the scan tool or the HDS indicates a
code for the fuel and emissions system.
Does the scan tool or the HDS indicate a code f or
the f uel and emissions system?
YES Perform the Troubleshooting Flowchart for
the fuel and emissions system. Recheck for code
P0710 after troubleshooting.
NO Go to step 2.
2. Disconnect the 2P connector from the ATF
temperature sensor harness.
3. Measure ATF temperature sensor resistance at the
sensor connector.

4. Turn the ignition switch ON (II).
5. Measure the voltage between terminal No. 2 ATF
temperature sensor connector and body ground.

Is there about 5 V ?
YES Go to step 6.
NO Go to step 7.
6. Measure the voltage between ATF temperature
sensor connector terminals No. 1 and No. 2.

Is there about 5 V ?
YES Check for loose terminal fit at the PCM
connectors C24, C18, and at the ATF temperature
sensor. If necessary, substitute a known-good PCM
and recheck. If the DTC recurs, substitute a known-
good ATF temperature sensor.
NO Repair open or loose terminal fit in the wire
between the C18 terminal and the ATF temperature
sensor.
