Engine Code 43 on 1992 Accord

[1992Accord]

Thought my experience might be helpful to anyone else that has a similar check engine light problem. 3 months ago the engine light on my 1992 Accord came on. I jumpered the diagnostic port and found that it was a code 41 (Oxygen Sensor). I replaced the sensor with a Bosch OEM sensor from Autozone and the engine light went out immediately. 2 months later, the engine light reappeared, this time with a code 41 and code 43 (fuel supply). I disconnected the Oxygen Sensor and rechecked the code which was now a code 1 (Oxygen Sensor). I cleared the code by disconnecting the battery and the code was then only code 43. Another new Bosch sensor did nothing. I was told to get the Honda Oxygen Sensor (2 times the price!) which looks different than the Bosch sensor. The installation of the Honda sensor seems to have fixed the problem as the engine light is now out. BTW, the performance was unaffected when the engine lights were on so there was reason to doubt the code was fuel supply related. Now we'll see if it passes the emissions test! I'd be interested to hear if someone has had a similar circumstance.
