P0522 is an OBD2 diagnostic code that is triggered when your Honda Odyssey 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 Odyssey’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.

Should be taken very seriously
The most common symptom is the oil light or an improper oil pressure gauge reading

P0522 Symptoms: Honda Odyssey
Here are the most common symptoms of P0522:
Low Oil Light/Gauge- While P0522 is often caused by a bad oil pressure sensor, you should treat the readings from the oil pressure gauge and low oil warning as though they are correct until you know better.
Ticking and Knocking-If your engine is ticking and knocking, it’s likely that the oil pressure sensor is accurate and there’s a problem with the engine or you need oil.
Won’t Start–If there was no oil pressure, your Odyssey’s engine very well could have locked up.
Odyssey P0522 Causes
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 Odyssey’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:
Low or No Oil-The first thing that you should do is check to see if there is oil in your Odyssey’s engine at all. If the crankcase is empty or really low on oil it can throw P0522. If this is the case, fill the oil back up, clear the code, and that may fix the problem.
Low Oil Pressure-If the oil pressure level is too low, this code can show up. It should show up with the oil light, or a low reading from the oil pressure gauge. Honda Odyssey Low Oil Pressure Diagnosis
Dirty or Wrong Oil-If there hasn’t been an oil change for a long enough period of time, it can interfere with the oil pressure sensor, even if there still is oil pressure.
Oil Pressure Sensor Wiring-P0522 indicates that the signal from the oil pressure sensor below it’s operating range. This could indicate a wiring issue.
Oil Pressure Sensor-The oil pressure sensor itself is very likely to be the cause of P0522, but looking at the oil and wiring first is a smart move.
P0522 Diagnosis: Honda Odyssey
This P0522 diagnosis order is written (like everything on the site) for the DIY guy who doesn’t have a lot of specialty tools.
1. Check the Oil
The 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.
2. Inspect the Wiring Harness
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 Odyssey’s exhaust and can get brittle over time.
3. Manually Check The Oil Pressure
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.
Conclusion: P0522 Honda Odyssey
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 Honda Odyssey!
It is set when the PCM detects that the signal coming from the engine oil pressure switch dips below standard levels. Code P0522 is commonly caused by engine oil pressure sensor failure, PCM failure, or a faulty instrument cluster.
Error Code P0522 is defined as Engine Oil Pressure Sensor/Switch Low Voltage. This means the sensor is indicating that the oil pressure value is too low, which is due to faulty sensor, faulty sensor circuit or low oil level.
The oil pressure switch is usually located in the cylinder block near the oil filter or its housing. Older vehicles might also have the switch wired to the oil pressure gauge.
A faulty oil pressure sensor or oil pressure switch can falsely signal a low oil pressure condition, causing the oil pressure warning light to turn on.
Low engine oil pressure can arise from numerous factors, including a low oil level, old or degraded oil, a clogged or dirty oil filter, a faulty oil pressure sensor or gauge, a worn or damaged oil pump, or blocked or restricted oil leaks or passageways.
Code P0522 is commonly caused by engine oil pressure sensor failure, PCM failure, or a faulty instrument cluster. Symptoms of P0522 include a lit oil pressure warning light, a stalling engine, and mechanical noises like ticking, knocking, and rumbling.
You should not take this situation lightly, as it is an indication that your engine has lost normal oil pressure. If you see this light on, we highly suggest that you stop driving your vehicle immediately and turn off your engine. Driving with this light on your dash can cause severe, irreversible engine damage.
On average, the cost of parts can range from $50 to $200, while the labour costs can range from $80 to $150. Therefore, the total cost can range from $130 to $350.
Functionality: The oil pressure switch is a simple on/off device that activates a warning light or alarm when the oil pressure drops below a certain threshold. On the other hand, the oil pressure sensor provides continuous feedback on the oil pressure, allowing the driver to monitor the engine's health in real-time.
While it might be physically possible for you to replace the engine oil pressure sensor at home, the risks associated with using a faulty or improperly installed sensor make it an inadvisable do-it-yourself project.
Oil pressure sensors go bad and eventually fail. When this happens, the dashboard light can become constantly illuminated. It can also cause an oil leak. If you keep driving your vehicle, you'll cause significant damage to your engine.
the oil pressure sensor connector is broken, it may cause the engine's oil pressure warning light to illuminate on the dashboard. While the truck may still operate, it is not recommended to continue driving without resolving the issue.
Dirt and debris: The sensor may become clogged with dirt, debris or sludge, especially if the engine oil is not changed regularly. This can prevent the sensor from providing an accurate reading.
Additionally, the labour required to replace an oil pressure sensor can take anywhere from 0.8 hours to 1.5 hours, with the actual time varying based on the complexity of the job and the mechanic you choose to perform the work.
Dirt and debris: The sensor may become clogged with dirt, debris or sludge, especially if the engine oil is not changed regularly. This can prevent the sensor from providing an accurate reading.
The oil pressure light is often triggered due to very low oil or no oil in your engine. This could be because the oil hasn't been changed in much too long or there is a major oil leak. Your oil filter can also be clogged, usually because of the lack of regular oil changes.
The average cost for an Oil Pressure Sensor Replacement is between $143 and $163. Labor costs are estimated between $74 and $93 while parts are typically priced around $70.
