Be careful researching for what year. 1996-98 is about the time when Honda was moving some of those sensors around from inside the distributor to down at the crank.

I don't know why the OBD-1 code (jumper & flashing light) would be different from the OBD-2 code (from scanner).

You can check each sensor with an ohm-meter, but that's not as conclusive as using an oscilloscope. Or an OBD-2 scanner which can display live data.

The TDC sensor is not available as a part. It's in the distributor in 94 Accord manual and I think 94-97 are all the same.

I had this code occur once due to my improper installation of the distributor into the camshaft keyway. When i tightened the bolts I bent an internal frame cause sensor misalignment and code error. I remove distributor and was able to straighten the frame.

A new (aftermarket) or used distributor can be purchased very reasonably. I would go w/ a used as they will be much cheaper. Check ebay or car-part.com for one near your zipcode.

If you got the codes right, Autozone misread them. P0420 is catalytic converter efficiency problem, not P0402. Code 8 (Obd1) corresponds to three OBD2 codes (P1359, P1361, P1362). All are electrical faults in the TDC sensor circuit. Might be worth getting a 2nd opinion on the OBD2 codes. If you have a TDC sensor fault the OBD2 code will narrow the type of fault down; disconnected, intermittent, or no TDC signal.

good luck

Read your post and mine. I wasn't questioning P0401, but P0402.

good luck
