Hello I will help you with your question,
The primary O2 sensor is the one you can access from the top of the engine
You will have to perform two "drive cycles" to have all the I/M monitors set as ready. If a code sets before the monitors are ready they will stop running until reset and you start the process over again. The monitors will be not ready once you pull the ECM fuse and the drive cycle will have to be compleded again
There is a TSB for code P0133 if that is what set

Applies To: 1998-02 Accord DX and L4 EX/LX LEV - ALL
MIL Comes On With DTC P0133 (Supersedes 00-017, dated September 11, 2001)
Updated information is shown by asterisks and black bars.
The MIL comes on with DTC P0133 (primary heated oxygen sensor slow response).
*Some brands of fuel and/or fuel additive packages may create deposits at the fuel injector tips. This build-up may cause slight air/fuel deviations between each cylinder. Build-up of these deposits, when coupled with very specific driving conditions, may cause the MIL to come on and the PCM to store DTC P0133.*
Replace the primary heated oxygen sensor (HO2S) and the fuel injectors.
For 1998-2000 models only: Compare the vehicle's ECM/PCM part number to PARTS INFORMATION. If the numbers do not match, replace the ECM/PCM.

John G raises good questions.
Here is a copy of the drive cycle for your vehicle once we determine what sensor you have the issue with
Completing the Drive Cycle successfully one (1) time should reset most drive cycle monitors to a "Ready" status. However, there are "two trip" monitors, which require that the drive cycle be successfully completed two (2) times, to achieve a "Ready" status. Furthermore, systems which use averaging, may require the drive cycle to be completed more than 2 times.Verify the status of the readiness monitors with the appropriate function of your scan tool.NOTE: Certain vehicles have known OBD-II Readiness issues. Please be sure to review TSB's for special circumstances and or exceptions to readiness monitor resetting procedures.Before Beginning the Drive Cycle Check the status of the Readiness Monitors, check for DTC's, correct faults, clear DTC's before beginning the Drive Cycle.Begin Drive Cycle The vehicle should be driven approximately 7.5 miles within a period of approx. 23 minutes (1372 seconds) from a cold start. However, due to manufacture variations, it is necessary to perform only as much of the Drive Cycle as is necessary to reset the required monitors to a "Ready" status. Operate the throttle smoothly to obtain best results. Do not shut the engine off during the drive cycle.CAUTION: Obey all traffic laws and drive in a safe manner!NOTE: Extreme driving conditioning such as very high/low temperatures, rough roads and high altitudes may prevent some monitors from attaining a "Ready" status.
NOTE: Remember, clearing DTC's or interrupting power to the ECM after the readiness monitors have been reset to "Ready" will require that the Drive Cycle be repeated.Completing the Drive Cycle successfully one (1) time should reset most drive cycle monitors to a "Ready" status. However, there are "two trip" monitors, which require that the drive cycle be successfully completed two (2) times, to achieve a "Ready" status. Furthermore, systems which use averaging, may require the drive cycle to be completed more than 2 times.

Sorry but I have been busy today and have not had time to get this to you
Usually the heater code is the sensor itself, if you used a Honda sensor and not a "universal" sensor the code will be cleared from current once the monitor runs successfully
If you have a voltmeter to check the heater voltage supply we can move forward with this
