What's up Everyone!... I apologize for more posts about my 98 civic.

So I recently replaced the Knock Sensor and the o2 sensor... Recently had to replace the speed sensor. When clearing the codes they automatically come back. I wen't to pep boys and he tried to clear the codes and they Immediately come back... weird huh? Does anyone have any suggestions of what it could be?

Again the Make is a 1998 Honda Civic EX model.

Which codes came back, all of them, or only certain ones? Have you checked your fuses? What about your wiring?

List the exact "Pxxxx" codes

Can not help without knowing which codes they are.

Yes I do. The codes come back.
It could be anything. Especially since you never bothered to say why you were replacing all these things.
Now go and post up what the codes are or you're just wasting time.

Codes:

P0325 "Knock sensor"
P0135 "Bank 1 sensor 1"

Those codes keep coming back.

Also the Speed sensor code came back on. Sometimes it flutters when going over 4000 rpm 5miles over, or 5 miles less than what the car is going. **This is from the replaced speed sensor**

Edit: I replaced the sensors because i failed the California smog test.

And another question, Would the front Sensor plugg'd into the Headers be bad aswell?

Check fuse 15, like the TSB said. Have you poked the wires with a multimeter to see if they're damaged?

Bank 1 sensor 1 is the 1st o2 sensor(pre cat) not the one further down. You possibly changed wrong o2

That's the one under the car..

Didn't think it was the one plugged into the headers..

I'll check all my ground
