SOURCE: check engine light on 1997 Honda accord EX
Hi
If the engine is running without any problems then The fault code which has flagged the checked engine light will either pertain to the upstream O2 sensor, a drop in catalytic efficiency, an EGR issue, or maybe even an EVAP issue.
A lot of EVAP issues can be resolved by simply ensuring that the fuel filler cap is on securely, otherwise a vacuum leak will be detected in the system and the check engine light will come on.
A drop in catalytic efficiency (P0420) is usually temporary and will stay away after a reset.
EGR issues can sometimes be rectified by removing the EGR valve and cleaning it, and the ports on the intake where it was sat, but there are occasions when it has to be renewed.
The O2 sensor issues are a wee bit different. There are a number of fault codes which relate to the O2 sensor, and which make the O2 sensor look faulty, when the O2 sensor is actually attempting to rectify a problem from elsewhere and isn't faulty at all. However, they could also be due to a fault with the O2 sensor. Basically, further checks should be made before condemning the O2 sensor should the fault code relate to the sensor.
Have a code read done and then have the codes reset and see what comes up.
Regards
Geordie

P1361 TDC Sensor Intermittent Interruption (I got this from Engine-Light-Help.com)
TDC should mean Top Dead Center.
It is the sensor that tells the computer the #1 cylinder piston is at the very top. And therefore, fires the spark plug.
Since the maintenance done above, I believe the the timing marks for the timing belt is not lined up properly. Being off by one tooth will cause this problem.

before you do anything, let the engine and exhaust line cool down first. disconnet the electrical connector to the sensor, spray some lubricating fluid like " WD 40 " to the thread of the sensor, allow for a few minute then use the right spanner to turn the sensor. here you go, the sensor is now removed. Installing a new sensor is just the reverse. Enjoy it.

This sounds a lot like a bad TDC (Top Dead Center) sensor. Of the many sensors on this model vehicle, the TDC sensor failure is common and is one of the few sensor failures that will disable your vehicle.

If it's running rough, chances are that it's misfiring. If the Check Engine light is flashing/blinking, it is definitely misfiring.
If that's the case, drive it as little as possible... Or straight to the mechanic because the more you drive it while it's misfiring, the higher the chance is of you ruining your catalytic converter.
