Default PCV valve

Hey guys,

I am struggling to get my car fix. I've been to the mechanics and they said my vacuum line needed to be changed. I changed that but my engine light keeps comming on. I will another diagnostic tomorrow.

Does anyone know where the PCV valve is located on a 1994 Pontiac Bonneville SE?
Does anyone know what else can cause the engine light to come on and also make my car not to start?

I've gotten two dianostic already and they won't tell me the code. Please help.

If the '94 is the same as the '96 (I'm not sure) it is located on top of the engine in front of the upper intake plenum. It is different than any PCV that I have ever seen. It is electrically controlled, so look for an electrical connection as well as vacuum.

On the OBDI cars (pre '96) you can get the codes by jumpering the "A" and "B" pins on the connecter where they plug the scanner in. If I remember correctly they are the two on the right side either side by side or upper and lower. Just use a "U" shaped wire or even a paper clip. Then count the check engine flashes. It will flash code 12 (flash, pause, flash flash) three times to indicate the system is working. Then it will flash any stored codes. A code 23 would be flash flash, pause flash flash flash. It will flash each code 3 times. When finished it will flash code 12 again. Or, you can get a simple code reader called "Creader" made by Launch for about $40 from Harbor Freight. They have both OBDI and OBDII readers. They are a must for the OBDII cars as the above proccess will not work on OBDII cars but a waste of money, I think, for the OBDI cars.

94 - series I
96 - Series II, different spot.

You dont' technically need tools, but a screwdriver and a needlenose will be a good idea.

Pull off the engine cover, the part of the cover that'* hooked in the middle is where the PCV is. Right next to, or under your plug wires. You just twist on that waffle looking thing, and pull it out. Take note of the order.

Make sure you keep all your o rings and only replace the part that'* in your packaging. Make sure everything goes in the same order, etc.

I got a diagnostic on my car. These are the codes that came up 341, 321, 361, 705, and 131.

So far I was told to change my crankshat sensor and my oxygen sensor.

Do you know of any place where I can do this because the place that I went couldn't do it?
