check engine light

My wife told me that the check engine light came on today on the CX-5 (2013 2.0Gas, 80K Miles). She did not notice drivability concern, except saying the engine 'might be' a bit louder at loads. I used OBD scanner and retrieved two codes: P0172 running rich, P013a downstream O2 slow switch...

A few weeks ago, the CEL came on. I took it to Advanced Auto, they gave me the code, went to the mechanic, and he said that it was one of the oxygen sensors. I paid for that repair, and by the time I came back home, the CEL was back on. I took it back, they said nothing was wrong with the...

every time it snows, especially when the temp is above 10degrees F & snow is a little more wet, within a few blocks of driving the orange wrench light will come on & the transmission shifts a little jerky/chunky. occasionally this will go away, especially if we aren't driving in the snow and...

My battery died last night. It was really weird as when we walked up to the car the interior lights were still on (normally they'd time out wouldn't they?) The car unlocked normally. I pushed start and nothing, red key on dash, flashing push button (orange). We tried to jump it but the key was...

Hey all. So a few months ago, the CEL came on, car wasn't running any differently, no power loss, same mpg, etc. but I had it read at Autozone as I don't have a reader. code came up P2177, system too lean at off-idle, right bank. I waited on getting around to it, but finally did earlier today...

Hi all, I was driving today and I got off the highway. The cars traction control turned on and the car would not accelerate. I basically rolled until I got out of traffics way. I hit the traction control off button and nothing happen. Stopped the car, put it into manual mode to see what gear I...

The check engine light came on a couple days ago on my MSP giving me code P0171, Does anyone know what this code means ??

I have a 2007 Mazda3 2.0L w/ 71,000 miles and have been experiencing a rough idle. Eventually the check engine light came on. I had a mechanic run a diagnostic test and code P0300 came back (random misfire). Upon further inspection, he recommended I replace these items: Crank position sensor 4...

We bought our CX-5 a few days ago and we had a check engine light come on this evening. My scanner says that it's a P0722 but I haven't been able to determine what exactly that means. Has anyone else had this code or knows what the implications may be? All I was able to determine is that it may...

I turned my MSP on today to discover that it was idling very rough and uneven, and the check engine light is flashing. I'd just ordered and received my timing belt components in the mail and was going to replace the whole thing in a few days - I really hope my timing belt didn't fail just now...

Hi to everyone on the forum! It was back in about 1998 that I rented an MPV to take five adults and our luggage on a 1200 mile weekend trip to Southern California. I wasn't expecting much given the load she was carrying, but that MPV surprised me by hauling us all up and down the grapevine...

Hello all, first post! And a challenging one too... 2003 Protege5, 107k Here's what's happening: most of the time car runs ok although the check engine light is almost always on. On ocassion, and more frequently, when completely stopped, the revs will go down to almost zero (but it has NEVER...

Check Engine Light (CEL) System Too Lean (Bank 1) Re: 2003 Mazda Protg5, 46,800 miles, All Stock. The CEL came on, took car to Auto Zone, got code - System Too Lean (Bank 1). I call my maintenance Mazda Dealer and they wanted over $300.00 just to change the Oxygen Sensor. I replaced the...
