So today after I finished bowling with some of my friends, started my car and had the check engine come on!!!!! So me n my buddies are mechanics and so tomorrow my buddy is gonna bring his scanner to see wats up with the code that came up! All I have done to my car is put the hi flow stillen intake on!!! So most likely my MAS(mass airflow sensor) has come on. So juss letting u guys know if that ever happens to you guys! But won't find out till tomorrow, so I'll keep u guys posted on wat code came up! But if any of u guys has had experince with this let me know!

 

Keep us posted!

 

I know that this sounds stupid and I'm certain that you and your friend checked this but the first thing I used to do when I got CELs on my 2k or 2k3 is to make sure that the Gas Cap is screwed on tightly.

The first time it happened in my 2k I was like WTF? I started checking the intake, disconnecting and reconnecting things and it still stayed there, I took it to Autozone to do one of those scans and then the guy checked the Gas Cap and then the light went off.

I felt about as tall as Tatoo from Fantasy Island.

Oh well, at least I didn't have to pay for a new MAF.

 

I checked my gas cap this morning and diddnt seem loose, but don't know felt weird wen I loosen it up so won't be able to find out later in da day for my buddy to get off work. Checked the intake and didn't look like I didn't have any leaks or anything!

 

I have learned over time, sometimes its good to start simple. Two things happened to me once. One, I ran out of gas (Fuel Gauge broke), and couldn't figure out what happened, I was about to call a two truck, but just decided to try gas, started right up. Two, car would go full throttle while driving. After taking it to a shop for 3 days and getting it back, the problem happened again. Then took it to a dealership, they called the same day and said we found your problem, the mat would not allow the pedal to come back up from the floor, by the way, that'll be 80 dollars please!

 

so what was the ses light ?


mines got 7,000 miles and been in at the the dealer for allmost 2 weeks all added up .
they still are clueless why it has a miss and ses light is on

 

The SES light has a long history. Back in Nov I had the problem and it was fixed by replacing the evaporator canister. A bunch of cars had a bad batch.

For more info see the "Sorry I bought this car" thread.

 

p0456 said small leaks or loose gas cap!!! and mine was probably a loose gas cap since its a new car!! so i juss deleted the code and if that code pulls up again den that means ders even more problems for me!! but it shouldnt!!!
