I have a 2002 Accord EX, 2.3 ULEV, automatic. The CEL light came on. I took it to Auto Zone to use a code reader, and codes came back P0700 and P0706. The P0706 is a transmission range sensor circuit. Any good resources on how to trouble shoot this, or any parts that are readily replaceable? Also, the D4 light in the instrument panel went out a couple weeks ago, when the car is shifted in D4. Could these be related?

Thanks
