    Default Error code P301

    Hi,
    I had one of my ignition replaced a long time ago.
    Now I just got a code P301. Is a cylinder 1 left or right side when you are looking at a motor (you are standing the front of a car)?

    Thank you as always!

    I thought #1 was closest to the water pump, but Iíve got no documentation on that...

    That's right. I would say common convention has #1 cylinder at the "front" of the engine. Typically where the water pump or crank pulley would be. Now with some of the new engines with things like the cam chains/belts at the rear, then I would think #1 would be at the front of the car. If that type of engine was transverse...well now that is confusing and would suggest looking at "the book".

    Thank you Astro14 and Bill!
    So I think it's the left one which is right next to timing belt and water pump.
    I know I can switch the ignition to find it out, but it's 20F here in NE, so I just replace the one I need to.

    Thank you guys as always!

    Hi,
    Just replaced it and it's running great now. It was the one right next to a timing belt (P301 code) as you guys told me.
    I don't remember how I loosen a screw for a cover right underneath of an intercooler hose (underneath of strut bar) last time. I didn't have right tool for it today, so it took 20 minutes to figure it out...

    It was cold, but sunshine helped me.
    Thank you again guys!

    As with all things automotive there is an exception to pretty much every rule.

    Normally the front of the engine (cylinder 1) is going to be at the opposite end from the transmission. V engines normally the #1 cylinder is the furthest forward cylinder.

    One exception that i know of is the Jaguar XK engine where #1 is to the rear, as fitted to many classic Jag's such as the E-Type
