Logged Larry 4 Miatas but who's counting!! Everything seems fine after that but I was just driving to work 0. I was just putting along in a parking lot when it happened. Logged Yeah, vacuum leaks are the first thing I'm gonna check once I'm off work tomorrow. This technician can even travel to your home or office if needed. The oxygen sensor sees a rich mixture and commands a leaner mixture to compensate. I thought it odd, checked everything under the hood, the filter on tight , oil level, etc.
Logged I'll definitely update this with what they say. I was sitting idling in traffic and it popped. While it is still possible to drive most vehicles registering the P2187 code, it is important to address the underlying issues at your earliest convenience. I have this same problem. Took mine today to the stealership.
Im a welder and i travel, so who knows how hard its going to be. The only other change recently has been the weather has cooled off significantly and has certainly made the car run incredibly well. The light reset, then about a week and a half ago the check engine light came on again. If the idle rises then you found the leak. Reset it a couple of times and it kept coming back. Once the code has been validated, the mechanic may consult professional repair manuals or use the appearance of any other trouble codes to narrow down the potential cause of the lean fuel mixture indicated by the P2187 code.
The front sensor is primarily responsible for the mixture, the second sensor behind the exhaust is used for comparison to the front sensor to determine if the converter is working properly. I had the code read and it said there were 4 codes. It's been very good as of late. However, both of these conditions have likely been there for a while possibly months without issue. Check the hose or connection between the sensor and the intake manifold all the way to the manifold for cracks or loose connections. I'm sure this is on here somewhere, but I'm on the blackberry and searching isn't quite as easy as it should be.
Step 1 Assuming that the engine is known to be in good mechanical condition, record all fault codes present as well as all available freeze frame data. Bernie, you said that you checked your vacuum hoses for leaks. Stealer said they check it and every thing is working as supposed to, including purge valve. Check all vacuum hoses carefully attached to the intake manifold, to include the one to the vacuum brake booster. Mazda 6, P0420 and P2187 togetherMazda 6, 2002 year of birth, Engine - 2. I checked around the throttle body to see if it was either of the two vacuum lines referenced above.
Mechanic did a detailed Diagnostic and it was the Intake Manifold Gasket causing air to get in. Need more help with a p2187 code? How do you get to that vaccum line. But from the weird engine reving at iddle, I don't have it anymore. Be aware though that while low fuel pressure can contribute to code P2187, this condition will almost always be indicated by a code other than P2187. I didn't worry about it.
It was around 45 deg F when it happened and I have read that cold temps sometimes accompany this code. Glad to hear it's gonna get all worked out. Glad to hear it's gonna get all worked out. What has your gas mileage been? Oddly, mine only began acting up once it got cool out. Since it is easy to be bogged down in small details, it sometimes happens that the code is resolved without realizing it, so rescan the system regularly to save time and effort.
I've entertained the idea that it's the fuel pump. Again I apologize if I'm not providing enough information. It also seems to be more prevalent during colder days. Seriously, I have no idea how that would even have happened. The strategy dictates that the driveability problems are observed and noted, then start with the most commonly found problems and progress from there. Not to mention if i turn the ac on it jumps to 17.
