Первую половину пути шел 130-140 км/ч, eco выключен. Вторую половину 110-120, eco включен, иногда, не на долго включал круиз. В принципе можно ехать еще экономичнее, если не крутить двигатель выше 2000 оборотов, но это же совсем не интересно.
И кстати нашел нормальное и не дорогое средство от жуков-самоубийц.
Остановился, нанес на стекло, через 2-3 минуты смахнул дворниками и помчал дальше. Ночью особенно актуально. Брал в Ашане, около 170 руб.
P0522 is an OBD2 diagnostic code that is triggered when your Jeep Grand Cherokee detects that the value being sent from the oil pressure sensor is below its normal operating ranged.
It is typically caused by a bad oil pressure sensor or an issue with the oil system, and should be diagnosed and fixed right away. While it is possible (and even likely) that the oil pressure sender/sensor is bad, there could also be a problem with the oil pressure.
Assume that you do not have any oil pressure until you confirm that you do. If there isn’t any oil pressure, this can keep the engine from locking up.
Your Grand Cherokee’s oil pressure sensor measures the oil pressure mechanically, and converts that reading into a voltage signal that the PCM (Powertrain Control Module) uses for the oil pressure reading. This reading is what you see on your oil pressure gauge and triggers the oil warning light.
Here are the most common symptoms of P0522:
P0522 is going to be caused by an issue with the sensor or sensor wiring (which would mean your engine is fine). Or it is going to be caused by an issue your Grand Cherokee’s oil level, viscosity, pressure, or cleanliness.
Since proper oil flow is so critical to the engine, this code should be treated with respect and not ignored.
Here are the most common causes of P0522:
This P0522 diagnosis order is written (like everything on the site) for the DIY guy who doesn’t have a lot of specialty tools.
T he first thing that you should do is check the oil level. If it’s full make sure that it looks healthy. If it appears to be black or grimy, it may be interfering with the oil pressure sensor. If the wrong oil viscosity was used it can also trigger P0522 even with a full reading on the dipstick.
Next, you should inspect the wiring harness running from the oil pressure sensor to the PCM. If it has any damaged wiring, that could be causing P0522. Don’t forget to make sure that the harness is still plugged into the sending unit and undamaged.
Wiring issues are one of the more common reasons that this code is thrown. The wiring is close to the Grand Cherokee’s exhaust and can get brittle over time.
Assuming that the oil level and wiring look fine, the next thing to do would be to manually check the oil pressure. You can use a manual oil pressure gauge to see if it’s where it needs to be. They are easy to use. Here’s a great YouTube video that will show you exactly how to use this gauge to check.
If the oil pressure from the gauge reads ok, you’ll need to replace the oil pressure sending unit/sensor. They’re cheap. If there is low or no oil pressure, you’ll need to figure out why.
It’s relatively straightforward diagnosing P0522. Knowing the actual oil pressure level makes it a lot easier. Feel free to leave a comment below if there is something that you would like to add and good luck fixing your Jeep Grand Cherokee!
