The 1997 Honda Prelude has OBD II, there is no conversion. You will need a scan tool or code reader that is capable of reading OBD 2 codes. From 1996 up all vehicles with few exceptions are mandated by the Government to have OBD II systems. This was put into place to standardize codes and make diagnosing problems easier.

There is no obd port. You can peel back the carpet under the passenger foot area and reveal the ecu. From there you can read the led flashes to find out what codes are being displayed.
if its a us Honda then its under the dash on left if its a UK Honda then its not obd compliant until 2001 actually i believe only 1996 and up year civics have an OBD port for plugging in the scanner..
I have the same code on my 2003 accord.
The obd 2 connector is located under the passenger side of the dash behind the center console, there is a panel that pops off for access
where is the plug to conect the code reader on a 1990 Honda accord
