SES Light Blinking

**lvbroham1** · 11-25-2008, 10:21 AM

Alright guys, through many of searches I've found out what a blinking ses light means (multiple cylinder misfire), and was worried about even driving the car to vatozone to get it scanned, but i did and here are the 4 codes they read.

P0200 X2
P0300 X2

After getting them scanned, the guy erased them and they haven't come back on even after the ride home, but i'm still concerned that they'll pop back up. Now i'm completely lost as to what a P0200 code is, all i know is that it has something to do with a fuel injector circuit condition. And in addition, I thought along with a p0300 you also get what cylinder it's misfiring on, but no luck, both P0300 codes didn't say what cylinder it was. This car is by no means my dd, but I would like to get this fixed before snowfall. Any help as to what is causing these codes to pop up is very much appreciated, and thank you in advance.

try ohm'ing out the injectors wires and make sure they are consistent across the board..secondly..try checking the inj fuses..look at your manual for the layout....if thats doesnt solve it..maybe a faulty pcm. have you changed anything on the car lately ?

Well I recently changed the head gaskets, and got a new tune. I went over every electrical connection 3 times before starting it. I know the tune wouldn't make the ses light flash. I'll check the fuses and make sure nothing is messed up. For ohming the wires, what ohm should they all be at, or should i just make sure they are all the same?
