These codes all indicate issues with the Injector Control Pressure (ICP) sensor circuit. The specific issues that the circuit is experiencing will depend on the exact code you’re seeing:
- P2285: Injector Code Pressure Sensor Circuit Low
- P2286: Injector Code Pressure Sensor Circuit High
- P2287: Injector Code Pressure Sensor Circuit Intermittent
With code P2285, the circuit will be giving a lower voltage than expected; with P2286, the voltage will be higher; with P2287, the voltage will be intermittent, which may mean it’s not present at all sometimes and working fine at other times.
More About the P2285, P2286, and P2287 Codes
The ICP sensor is part of the hydraulic electronic unit injector (HEUI) system present in some diesel engines. In traditional diesel engines, fuel pressure is used to open the fuel injectors. However, in some engines, oil pressure from the engine is used to open these injectors. In this case the ICP sensor monitors the oil pressure produced by the Injector Pressure Regulator (IPR), which regulates the oil pressure going to the fuel injectors. If this data is missing or in some way not coming in correctly, it may not be able to add fuel correctly to the engine, resulting in all manner of issues.
What Are the Symptoms of a P2285 Code?
There are many possible symptoms of the P2285, P2286, and P2287 codes. You should see the check engine light turn on, especially since this code can cause serious driveability concerns. Outside of that, symptoms may include general engine performance issues, including rough running and hard starting, with the problem potentially progressing to a complete no-start condition.
What Are Some Causes of a P2285 Code?
These are generic trouble codes, which means that the cause can vary depending on the problem that you’re actually experiencing. For example, the problem could simply be due to issues with very low engine oil, or it may be as serious as a defective PCM; although this cause is exceptionally rare and will almost always come with other problems as well. Other common causes include issues with the oil pump, ICP sensor, or IPR, as well as wiring problems, including a damaged connector.
How Serious Is the P2285 Code?
If the car can’t drive at all, then the problem is obviously very serious. However, even if you’re not experiencing a no-start condition, you should still assume that this issue is very serious. This is because any problem within the engine is naturally going to result in serious concerns for the engine overall. If your vehicle is unable to pump in fuel accurately, then you could start seeing issues elsewhere in the vehicle, even if it starts out as not showing many driveability concerns. Assume the problem is serious and approach it in that manner.
Can I Still Drive with a P2285 Code?
If your vehicle is still able to drive and isn’t experiencing a no-start condition, then you are still going to be able to physically drive. However, that doesn’t mean it’s necessarily a good idea. The more you drive with a vehicle that has these kinds of concerns, the more likely it will be that you will experience more severe engine issues, which can result in serious concerns over time. Instead, fix the problem early to avoid more expensive and more difficult fixes.
How Easy Is It to Diagnose a P2285 Code?
These three codes can be very difficult to diagnose, as they’re generic codes that can be set across many different makes and models. Additionally, there may be an oil pressure problem within the engine’s lubrication system, causing it to lose system pressure. That means you’ll need to go through an extensive diagnostic process to determine what the core problem is. If you can’t fix the problem by simply topping up the oil in your vehicle, then the problem may be more extensive than you can fix at home, which can mean it’s best to get help from an expert.
How Difficult Is It to Inspect a P2285 Code?
The inspection process for these codes is equally as difficult. It’s not especially common to inspect the area of the HEUI system, which means that you might not have a lot of experience with it. If you don’t have this experience, then it can be a complex and confusing process, one that you might not be well-versed in. Instead of trying to inspect it yourself, you might want to get help from an expert.
Need Additional Help with Your P2285 Code?
For many people, the P2285, P2286, and P2287 codes are very confusing and difficult to understand. If you don’t have a lot of experience in the realm of fuel injector systems, then you might not want to deal with them yourself, which is where an expert comes into play.
KBB makes it easier to find a repair shop in your area that can help you fix these problems. No matter what issues you’re experiencing or what type of car you have, one of these local professionals can help you determine the right solution.
Additionally, because this is a generic code, it’s very common to see other codes alongside this code. You can discover more about these codes using the OBD-II database from KBB.
