The car is running very well. I don't think that this will harm the engine as it only happens occasionally and briefly but any Nathan type advice would be appreciated. Oxygen sensors are installed in the exhaust system. When I refitted the cleaning hadn't made any difference. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. In reality, every case is different.
The engine temp was normal 220f. This will momentarily stumble for like a split second then clear out. What are the symptoms of the P2190 code? Codes came right back after a reset. I don't know want Bank 1 or Bank 2 mean in these codes. It was actually pretty clean which surprised me. Different from yours but lead me to a fuel delivery diagnosis for the Fuel Pressure Sensor.
What causes the P2190 code? Googleing your trouble code yielded the info above on both Pontiac and Mazda cars so Im prett confident of the answer. It only happened once this afternoon during acceleration on a mildly spirited drive on a country lane speeds 40mph-70mph in 100f heat. No rhyme or reason when its going to occur. The result will be a misfire while idling and possible misfires while driving. He obviously tried to do this with the air intake tube in place.
I basically covered the grommet with oil resistant silicon. Ran really well for a couple of months and then started playing up again. A more observant owner may notice loss of power, slight hesitation or a rough idle. There are numerous parts in the ignition system that can fail and create this condition. The vehicle starts and drives fine.
This is very helpful in narrowing down the possibilities. It could have to do with the new aluminum noncollapsible Alta Turbo Intake pipe as opposed to the old Alta silicone collapsible hose which I installed last weekend. Boy, do we have an info site like no other! Some code readers translate it for you, most don't. A variety of failures can cause this condition. P2189 trouble code definition The most environmentally friendly and power efficient air-fuel ratio is 14.
In some circumstances where the use of a vehicle requires extended idling, the problem this code is reporting will likely result in the fouling of the spark plug for the affected cylinder. This is part of the theory. This code may also be caused by a lean fuel condition caused from a faulty fuel pump, bad fuel pressure regulator, clogged fuel filter, or engine vacuum leak. I have gotten it a couple of times, but then it goes away. Each code does not have its own special light or pattern of flashes. How does a mechanic diagnose the P2190 code? How serious is the P2190 code? There are only a few parts that can do this. Here's what I have done over about 12 months 1.
Once it is determined this code needs to be addressed, the mechanic should check scan data looking for clues to point him in the direction of the problem. If the ignition system fails to create a spark at the spark plug, the injected fuel will not burn and will be pushed out of the cylinder into the exhaust. Most cases have been after an aggressive drive, and the problem is apparently a software issue that can be fixed with an upgrade. If you don't find anything I would next suggest cleaning the throttle body. Any one know what that P code means? Typically, deviations that exceed twenty-five percent of the long-term fuel trim desired value will cause a code to be stored and a malfunction indicator lamp to be illuminated. If nothing is done to address this code, more obvious symptoms will eventually result.
I would recommend have a dealer trace the problem with their diagnostic tools for you before you start chasing the problem down and throwing new parts at it without positive results. I got the car back from the shop today after new drive shafts. A technician can now ask him or herself what can affect only one bank and not both. I did clean the throttle body. Doesnt do it all the time Wouldnt a dirty Throttle unit also cause a rough idle more consistently? Sorry for the questions,just trying to understand it all The amount of unmetered air depends on multiple factors such as location of the leak, current value of vacuum, size of the ingress point, air density, etc. If this code were present on a vehicle such as a police car, it would be more of a problem.
Interesting: the last time I asked you about code P2188, it was the old collapsed hose not letting in enough air and now the new pipe lets in too much. I reckon there was a one centimetre gap in the seal. But the general approach is the same as described above by cbotb. Hi Joe D The good news is that you are not on your own but the bad news is that I've been chasing these codes for 12 months and not eliminated them. I figure if it was a vacuum leak it would do it consistently but this only happens for a split second almost. A mechanic should begin by. If a condition exists that sets this code, the vehicle will likely begin to misfire the longer it idles.
