The check engine light keeps coming on. so then i read about it on the internet and it said to look at my ecu. so i did and it keeps blinking once every 3-5 seconds. what does that mean? is it bad?

nico91civic Posted June 7, 2007 Share Posted June 7, 2007 the blinking light on the ECU is an error code description of the codes can be found here http://www.hondahookup.com/info/error_codes.php Link to comment Share on other sites More sharing options...
spike10197 Posted June 8, 2007 Author Share Posted June 8, 2007 so this is the problem that my ecu is saying Heated Oxygen Sensor (HO2S) so how do you change that? also where is it located? Link to comment Share on other sites More sharing options...
nico91civic Posted June 9, 2007 Share Posted June 9, 2007 well the O2 sensor is located either right off the header by the head or right before the cat on the top of the exhaust manifold (somewhere off your exhaust). you will need an O2 sensor socket which is a normal socket with a slit for the wire to fit through and alot of penetrating oil. I would locate the senor and start oiling the piss out of it. I would use aerokroil if you can get it but wd-40 should work too. also if you have trouble with the socket gripping get a hose clamp to put over the end after its on so its less likely to twist due to the slit Link to comment Share on other sites More sharing options...
