My check engine light went on right before i was going to take it into a smog cehck. pulled the codes, here is what i got:

P0325

Automatic ka right?

Knock sensor = replace (might have one laying around)
Evap small leak = check for leaks in the vacuum lines, fuel lines, charcoal canister, gas cap, etc.
Vent Control Valve - probably has to do with the evap, could be the sensor or just a vacuum line.
Shift Solenoid Valve = something to do with the tranny, do manual swap to fix this or look for that small metal thing on the driver's side engine bay and make sure it is plugged in. iirc it is bolted to the the engine bay side of the wheel well with two 10mm. If that is unplugged it will throw that code. Feel free to correct me if i'm wrong, when you get old the memory starts to go.

Whats the easiest way to get to the knock sensor?

Whats the easiest way to get to the knock sensor?

Probably from underneath. iirc it is held on right under the head and intake mani by a single 12mm bolt or is it a 10mm? I can't remember. It is a huge pita though. Find someone with tiny asian hands to help you.
