Both of which register a value of 0 - with Lambda Partial Self-Adaptation decreasing from 0 to -0. On the opposite end of the scale, you may note rough idling, lack of power on acceleration, even misfiring or stalling, which tends to get progressively worse as the engine warms up. It happens to the best of us! If it steadily drops, this means you have a leaking fuel injector or fuel pressure regulator. Seems odd that the intermediate shaft is stuck in the first place, however. A good idea would be to check the spark plugs again for fouling. Ashraf- The first thing I would check is the mass air flow sensor for contamination.
Her idle then fluctuates about 100rpm constantly. The problem is that i have replaced all 4 of my O2 oxygen sensors but still i am getting codes P0172, P1152. I recently 4 months changed turbo with its oil pipe at the dealer original oem. If it sticks, you have a faulty sensor. How do you troubleshoot code P0172? As a matter of fact, this error code is very similar to P0175, in some cases and scanning tools, the vehicle may show both codes simultaneously. Im sorry for long reply but I thought maybe u need this information to have a better view of this problem.
Let us know what you come up with. Rough idle and very poor accelaration unless i floor it. I have a 2006 Audi A3 1,6 petrol with 182000Kms on the clock. There is an emissions hose. ملاحظة سريعة لكل شخص يعمل على شفرات تقليم الوقود: استبدال أجهزة استشعار نسبة الهواء للوقود أو مستشعرات الأكسجين لن يؤدي إلى حل هذه المشكلة. Recently its been a been shaky, hesitate when running slow and has stalled on 2 occasions automatic car My Fuel Trim bank 1 long term is -3.
I dont know where to start with fixing this problem. I read that cat converter should be checked and most likely replaced with turbo replacement. How serious is the P2097 code? Diagnose and repair a cylinder misfire before attempting to diagnose a rich condition. The engine was probably sucking in a steady venturi of oil every time I hit big bump! Are you using factory coil packs? Having looked through the logged data - a rich condition was encountered with a 0. If the engine is running rough, that would indicate a misfire, the excess unburnt fuel and oxygen throwing off the fuel trim readings.
Turn the engine off and make sure fuel pressure stays stable. How to check O2 sensor using monitoring obd data? Please help Hello Benjamin, I loved your description and detailed information about this code. And While im driving it is reaching 1600 psi. Fuel pressure should be 40 — 45 psi, whether the engine is off or idling. Need to find a wiring diagram for this car to diagnose further. In any case, I think you might have multiple problems. Has the fuel consumption suffered? I have mazda cx7 2010.
Caution should be taken when the last test is done as the exhaust can cause burns. Found fender under airbox covered with oily dirt. Thank you for the reply. The vehicle will then be raised and inspected for exhaust leaks. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. If the oil smells like fuel, change that, as well.
Also, vacuum leaks would lead to a lean problem, not a rich problem. Old vacuum lines can crack, or there could be carbon buildup in the port feeding it. If fuel pressure still drops, this means you have a leaking fuel injector, which could definitely cause a rich code. Went to check, code P0172. The computer is no longer able to automatically adjust the mixture to the correct ratio.
I know these can be complicated issues, especially when they all come at once. Inspect the Bank 1 injectors for leaking, refer to. A Check Engine Light will accompany the P2097 code as well as a failsafe mode. I went to the local auto parts store, replaced the hose, tightened it with the proper clamps, ran it for about 10 miles; and was smog ready. The other codes that tend to pop up along with the P0172 are P0300 random misfires detected, and those have been on cylinders 1,3 and 4. He said the fuel pressure is fine and all the hoses are well fitting.
I think I would start with checking the spark plugs, perhaps doing a compression test, and a fuel pressure test. There are two simple tests for them. What repairs can fix the P0172 code? Over time, however, dirt and grime builds up, and it can easily find its way into the engine and control systems. These are easy to see and indicate an exhaust leak. For V6, V8 and V10 engines, Bank 1 is located at the side of the engine that contains cylinder 1. These include the manifold absolute pressure, mass air flow sensor, and the oxygen sensors.
