[lulu44321]

okay its saying circuit malfunction bank 1 knock sensor malfunction replaced the plug and the o2 sensor but the light is still onbut the car idles fine and doesnt stumble when driving but cant find the problem

[Wc240]

if it said knock sensor circuit, why did you replace the o2 sensor? what plug are you talking about?

[lulu44321]

sorry o2 sensor bank 1 circuit malfunction and knock sensor circuit malfunction

[Wc240]

you cleard the codes after you did the repairs right? when it says 'circuit malfunction' that doesnt neseccarily mean the sensor itself, means the ecu cant get a signal to/from it. look for damaged wires/connectors, bad connections, etc

[lulu44321]

yep didnt have a chance to clear the code but check the wire and replaced the one that looked a littlle burnt off the header but took it on a drive for more than 50 miles so it should have learned

[Wc240]

no, it takes alot more stuff to do it like that. clear the codes, THEN take it for a drive and see if it comes back

Make sure you clear out your codes after addressing the problems.

I would check the fuses to be safe because if the wire was touching the header, it would have grounded and blew a fuse. The code for the knock sensor may still be throwing the light. I as well ahave a knock sensor code but its a soft code
