Check Engine light on - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hi, I just got my car back from the mechanics and I noticed that my Check Engine light is on. They had to close soon so they weren't able to diagnose the problem. I'm going to need to drive my car today and tomorrow etc, and I would like to ask, how do I diagnose the check engine light? My car is 1995 240sx ka24de OBD I.

You should be able to pull codes off the ECU's light. I don't remember the procedure off the top of my head but it's listed in the FSM.

If anything, start off with disconnecting the negative battery terminal first for a couple of minutes to reset the ECU. If that doesn't work refer to the FSM to see how you can check ECU codes.

Good Luck!

^ No. Now you just get normal MPG. Your car just sucked your gas like 10 cent hooker.

Dude, get an FSM! C'mon you've been here for 3 years and you're asking questions as if you've never seen a 240SX before.
