okay so my car is throwing 2 CELs. it gave me #1 which is the O2A - Oxygen sensor #1, and it gave me #23 which is the knock sensor. just to double check, the O2 sensor is on the downpipe correct? also where is the knock sensor located? could it be bad sensors or just a bad connection on the sensor??

yes the o2 sensor is on the downpipe, i cant remember how you test to see if it bad or not. and it could be a bad connection to the sensors but i would assume 9 out of 10 times for 02 sensor its bad(not hard to replace either). just my .02 cents.1990 Accord 4dr EX R.I.P
