Tuners I have a Civic EK3 issue. A few days ago, I noticed my engine (D15B standard) check light comes on everytime I start the vehicle and it remains lit once the vehicle is on and running. This never occurred before, I did a diagnostic check and no errors were detected in the result.

The EK3 works normal as before and there is no sound or performance changes that I’ve noticed at all. Once the civic is on this light is always illuminated.

Any advice?

Thanks for the info red_dragon I'll check it out but still new to alot of this stuff...

did u do an engine wash of have coolant leak of any sorts

alexfos101 about 2yrs ago i did the last engine wash and the check light was on for a day or two and then disappeared, I guess water in it had to dry off completely and then it never came back until now. Since then no engine wash was done and surely no coolant leaks either.... this thing is hard to pinpoint and frustrating...

follow the link I posted

but if its odb11 since its an ek3 you cant jump the connector. you need a scan tool not so?

^ nope not with OBD2A

just follow the steps

cool i learn something everyday

Thank you red_dragon!
I followed the link and I got an error code 65 for the check light.
Although the ABS does not illuminate at any point after start up/driving, I got Four codes for it...61, 16, 17, 54
I guessing as the ABS light don't illuminate when driving it may not be anything severe and can perhaps be overlooked?
I will look into the engine check light error code. Thanks again

Error code 65 - Oxygen Sensor Heater (Secondary)
malfunctioning or defective oxygen sensor heater

Does anyone know exactly where this sensor is located in the ek3?

on your exhaust manifold

also depending there might be 2

if your car had a catalytic converter sometime there is one on it or after

Thanks red_dragon
