Check the plug and make sure it's making contact first.

 

well ondemand says that the cyp sensor is located inside the distributor. it says to check the resistance of the wires on the connector then voltage(didnt get the specifics but i can if you like). buttttt if those check out ok then it says to replace the whole dizzy since the sensor is INSIDE the dizzy. its not accessible from the outside

 

ive heard of people changing out a sensor i believe there is a walk through on this site, or it might just have been inner seals. you'll have to do a little searching i know there is info on this out there.

deffinitly check your connections as i had 99 (cylinder at TDC) sensor which is in the distributor and it was just a loose wire.

 

I tried replacing everything on my dizzy. And after all that I still ended up buying another one cuz the light would not go away. Save yourself the headache and just replace it.

 

I got a 1381 code, just bought the car (2000 GSR) and tried erasing the code with a scanner only to have the code come right back up immediately each time I fired up the engine. Well, I pulled the spark plug wires and oil came gushing up from 3 of 4 spark plug passages. I am convinced this is why I am getting the cylinder code because the wires are wet with oil and ignition signal is disrupted. Anyway, I got some of the oil falling into the cylinders as I was removing the plugs to replace them. I had to buy new wires and a valve cover seal kit but now I am wondering of I will be able to fire up the car with all that oil on top of the cylinders.

 

i dont think that should be a big problem honestly now im not an expert so dont take it just on my word, but as long as its not like a ton of oil it should be fine, that is how you perform a leak down test is it not? so should be ok as long as the oil amount isnt over a table spoon or so

 

It was quite a bit of oil gushing out, I think at least 2-3 spoons fell into the cylinder holes. But I am thinking it will burn off once I get it going.

 

well the oil coming out of the spark plug hole is not a good thing if its gushing. i would recomend running a compression test on those cylinders. if its "gushing" sounds bad. possible blown rings. and a leakdown test is when you shoot compressed air into a cylinder to find out where air is coming out. a wet compression test is where you squirt a little oil into the chamber to try and determine if the rings are indeed blown.
i agree with mulisha. just replace the dizzy. it saves a lot of time and money even though it may seem like its more expensive.

 

Yeah but the oil came out before I took the plugs out so I think it accumulated there because of the bad seals. Strangely enough the car was running with no misfires while this was going on.
