Check engine light

6k and no CEL so far. It's kind of funny since mine was one of the early ones (purchased June 6th.) It does, however, go in on Monday to get the drive shaft replaced.
 
CEL light again

On my fifth CEL light. All for the same reason. First they changed the leak detection pump, then they reset it, didn't do anything else (said my gas cap was loose, yeah right!) Next came the new gas cap, then the new software update, now yet another CEL light. I've got 4000 miles on the vehicle. At least I'm making a lot of new friends at the Mazda service dept. I wonder what their latest fix will be??

G-Papi...what's the drive shaft and what is the problem with it? Just curious. No CEL yet...1500 miles on her.

There's a TSB on it . . . let me look . . . it's on early models (I got my CX in June) where there's a metallic "clank" the first shift from park when everything is cold.

Mazda designed a new driveshaft with a damper that was standard for all the later models. There was a thread . . . lemme see
 
Still not sirius?

Day 10 with no Sirius & my 3rd CEL. Not a good day. (2,150 miles)

I just wanted to ask you if you are still having issues with Sirius...also wanted to see if your CX-7 came with a 30 day sirius trial when you first purchased it. I may have solution for your from my dealer for the lack of Siruis service.

I've had the CEL twice now, the first was at around 250 miles and the second at 2550 miles. The first time, dealer said it was the gas cap not fastened securely. OK, I can buy that since I was still on the first tank of gas and the dealer is who filled it up. The second one is still on as I'm waiting to see if in fact it will go off on its' own as the dealer has told me... make sure the cap is securely tightened and go through several start/driving cycles. Like many others here, I always turn the cap around 3-4 times so I know it's secure.

Now I recall someone mentioning the CEL condition being mentioned in the owners manual, so I went looking and found this:

The check engine light may come on in the following cases:
1) The fuel tank level being very low or approaching empty.
2) The engine's electrical system has a problem.
3) The emission control system has a problem.
4) The fuel-filler cap is missing or not tightened securely.

After seeing item #1, I thought what the heck... why on earth would Mazda consider low fuel level as a CEL condition? Then I had a revelation... normally I fill up before reaching a 1/4 of a tank remaining, but both times I've had the CEL condition I had let the fuel level go below a 1/4 of a tank. Now I'm wondering if anyone else who has experienced the CEL condition has noticed this. If this is happening due to letting the fuel level go near empty, that's total nonsense.
 
I've gone pretty much all the way to E on every tank and never had a CEL with 4200+ miles now. It does have a low fuel light so I'm not sure what that CEL condition stated in the manual is all about.

uhh, that light is just telling you the tires are low
look at it carefully, it looks like a cutaway of a tire!
Yeah I noticed that when I got in the car. I now have a cel but I havent checked the mileage. Ill take her in this weekend for a check up and to have the autolock turned on.
 
OK guys. Here's my question. My CX-7 is an early production model (purchased early June.) So it probably has the gas cap that's causing CEL's for everybody else - only on mine it hasn't. I'm at 6k miles.

Should I ask for a new cap, or just leave the darn thing alone, and hope for a continuation of my lucky run?

I'd leave it alone. Picked mine up in July and no issues with mine at 4700mi thus far.
 
Joining the club

Got mine at 4k, but I had a Hyundai that had the same problem with the CELs and tighten the cap again and light came off a couple days later. But just like G-papi should I ask for the cap even the light came off.
 
Now What?

OK I've got the same issue! Had the gas cap replaced in August, Leak Detection Pump two weeks ago. Now what? I know that they'll try to tell me (again) that the gas cap wasn't tight.(pissed) Come on, this is getting old!

Question: Have they, since August, improved "replacement" gas caps that they can put on?
 
Get It Fixed

My CEL came on this morning, at 324 miles. 40 minutes at the dealer, put on the redesigned gas cap, reprogrammed ECU. I am surprised that the dealer I bought it at didn't just do it before delivery (which was last Saturday).

TheMAN posted the dealer info that said there was a range of VINs that had bad caps, in page 7 or 8 of this thread. Check the spread and if you're in it, take it in. Why wait to get it fixed? It's free, and if the light comes on, you won't know what it's for--gas cap or something else.
