I know your dealer "sucks ****"—most Mazda dealers do—but maybe there 's another Mazda dealer—a good one—within, say, 50 miles or so? First thing I do when I get a car is locate a good service department. I'll drive an hour out of my way if I locate one. They're perfect for this kind of stuff.

I like to go to the dealer once or twice a year just to make sure I'm caught up on ECU flashes.

Besides, there aren't a lot of rotary mechanics out there. If you need work on your engine some day, might as well take it to someone who knows what the hell they're doing.

Just my 2˘. Glad you got this solved.

 

Driving around with no dipstick could load your oil with dust/owls/water/leaves/road grit.

Get your oil changed soon.....

S

 

The Dipstick should be here in a couple of hours. I'm going to have the oil changed soon anyways.

Sneak Peek: I just ordered Wheels and Tires too...

 

LOL

Be prepared for the possibility that its not the sensor, but the CAT.

 

It was only like 3 days without a dipstick... Unfortunately, I can't tell if you're serious or not. Do you think it may be my cat?

 

Also, I only drive like 15 miles a day so it's not like I've been whippin' all over the place....

 

dude I dont know how much you paid for that baby... probaly a ton.. but you could just get a universal one from auto zone($70.00) and wire it in from the stock harness.. could save you a ton! I know that it works because I did this myself... car runs perfectly and no more check engine light. Got the idea from a reputable rotary mechanic.

 

also rip that heavy *** cat off and and get a midpipe.. you wont have to worry about a clogged cat ever again.

 

Emissions good sir. Don't know any crooked garages around here. Actually I paid less for the OEM sensor than I did from the ones at AutoZone. I priced them while I was there getting the code read.

 

I too thought that MM. Hope the new sensor works.

Did you ensure that the connector wasn't just loose?

 

****. Anyone want to give me a recommendation on a replacement cat?

 

Also, is there not a seperate code for Cat Failure? P0037 specifically stated that it was a rear 02 sensor failure. I'm not doubting anyone chiming in that that's the possibility; I'm just trying to understand.

 

If the CEL bothers you that much and it turns out to be a clogged cat and not the sensor, make sure you get a hi flo cat not the midpipe as suggested earlier.

I have a permanent CEL since my resonated midpipe.

 

Is there any way I can tell that it's the cat and not the sensor from some sort of noise or smell or anything?

 

UPDATE: Just got a call from the shop I used and they said it appears the O2 Sensor did the trick. Will post a final update when I get it back in a few hours.

 

When I installed my mid-pipe I did get a cel, all I did was clear the ecu and havent had one since... I also passed emissions cause all they did was hook up a computer to the OBD-II and as long as there was no exsisting code she passed it! It was really smelling up the place too HA!!

 

Lol. Tsk Tsk. While I love performance, I personally want my car to be as green as possible in doing so.

UPDATE: Got the **** sensor that was in there before and it sucked ***. I can see why it threw the code. No more CEL. Car is running well; therefore all is well. I hope this thread can help some people later down the road.

 

Glad you got it resolved. I know how infuriating the CEL can be.

 

Here's the culprit.

 

My 04' CEL comes and goes and is on now. I take it in and my dealer gives me a loaner (very nice!) and they have replaced O2 sensors and catalytic converter but it still comes and goes. Doesn't run bad. They are just as mystified as we are tho. Might just be an RX-8 "Gemlin". Shouldn't Mazda figure this all out?

 

Get the code and post it. Could be the dreaded Evap Leak. You may just need a gas cap.

 

SOMEBODY HELP!

I too, had a P0037, check from Autozone several months ago. The code first appeared after I changed the stock air filter for a K&N drop in replacement. I've looked around for loose hoses but haven't seen any.

So, I assumed that my problem was the rear O2 sensor, as the P0037 indicates. I ordered a Denso exact fit, and installed it this morning. I tried clearing the CEL by disconnecting the battery, pulling the Room, Door, and Window fuses, and also by rapidly pressing the brake pedal 20 times. None of those procedures cleared my CEL, and it comes on immediately every time I've started the car after each procedure.

Does anyone have any other suggestions for clearing the CEL? I have not driven the car very much since replacing the O2 sensor, maybe just a total of 5 miles, but I thought one of those procedures should have forced the CEL to clear.

Do I just have to wait and drive the car a few more days to see if it goes away, or should I go to Autozone and read the code again?

Any help would be appreciated.

 

+1

Just got my first CEL ever. It came on after right when i was about to drive my car home from work... i know it wasnt the gas cap. Im gonna get it scanned hopefully tomorrow. I do have a HF cat on there from Rotary Performance. I hope it isnt that...

 

Does anyone have any idea where I can take my 8 for problems that isn't over an hour away from Terre Haute, IN?

If I HAVE to drive all of the way to Indy, it's going to be a huge pain in the *** everytime.

At the moment, I need a code for my CEL that reared its ugly head this morning.

 

I'm in the same situation. My CEL is on and I live in an E-Check county in Ohio. They won't test my car since the light is on, and I have a $2k Matco code reader. I reset my codes but the light won't stay off on the second startup, problematic for anybody trying to pass E-Check.

Right now after reading all these posts I'm gonna try to replace the rear O2 sensor. After that I'll open my dash and disconnect the CEL itself... R-tards @ E-Check won't know the difference, and they'll think my car's been serviced by a dealer since there's no code history.

God bless the Eight because I know we all love it, but I've never owned a car so idiot-light happy. I especially love the green "courtesy light" that comes on to let me know everything's cool with my headlights. I'm not ignorant enough to believe this is the last time I'll wrestle with this problem...

I'm surprised nobody's called anyone a "newbie" on this site so far... that BS is the reason I left here 2 years ago, now I've come back and hopefully order's been restored. Rest assured I have a roll of quarters all ready for the mouth of anybody with the cajones to type that word on this board...
