I just replaced the crankcase vent hose (the one that connects oil separate and dip stick). Then, I reassembled all the necessary parts(not included heat shield and fuel rail cover). After I started the engine, the engine light is still on. In addition, EML and DSC lights are also on now.
I do not know much about cars.
I might accidentally adjust the length of line that connecting the gas pedal and throttle body because I did not know what that is.
Anyway, Does anyone know what might cause the this issue? Is it possible that my adjustment cause the problem?

Thank you!

Before I replaced the hose, only the engine light as on.

What almost always causes the EML on a 323 is the throttle body. Given you have to go near one of the main "junction boxes" while replacing the hose you did, you may have bumped it or torn a wire, or even disconnected it. I'd start there.

Thank you. I will check it tomorrow.

Thank you. I will check it tomorrow.

If you have a scanner the OBD2 codes would help us help you too. :thumbup:

I found out that the throttle body was dirty and the butterfly was stick to the edge. I cleaned it then reassemble all the parts. Now EML and DSC light are off but the engine light is still on. Thank everyone for the tip. Hope the engine light will be off after I drive a little bit.

Yea, might want to think about a new throttle body. On your car, they are problematic and will leave you stranded if you aren't careful.

The engine light is off now.
