When it comes to your 6.0L Powerstroke engine, some or a lot of the problems or symptoms that might manifest might be due to the Injector Pressure Regulator failure. The good news is, once you are familiar with some of the 6.0L Powerstroke Injection Pressure Regulator valve failure symptoms ( IPR valve failure symptoms ), it gives you a head start on how to tackle the problem with your ford engine.
A properly functioning IPR valve works to control the pressure of the oil generated by the oil pressure pump. Generally, the IPR valve has to ensure that the oil maintains the perfect pressure. When oil pressure is great, every other part of your vehicle and engine functions properly.
However, with a bad IPR valve comes a host of trouble we would address in this article. We’d show you how to perform a 6.0L Powerstroke IPR valve test and how to identify 6.0L Powerstroke IPR valve symptoms and how to go about replacing it. So sit tight, and let’s go straight into it.
6.0L Powerstroke Injection Pressure Regulator Valve Test
If you’ve recently changed your IPR valve but you’re still experiencing the same symptoms, don’t give up hope yet. You can always conduct an IPR valve test to be certain that the IPR valve you got is the problem. With a simple test procedure, you can save yourself the stress of changing the IPR valve, especially if it’s not the problem.
So, what’s the best way to test an IPR valve? It’s to use a diagnostic tool. Diagnostic tools present an easy way to test your IPR valve. The number one rule your diagnostic or scan tool must succumb to is that it must read the IPR and the parameter IDs of the ICP. You can make use of the 6.0LHPOP test tool. They are durable and make it easy to detect if the IPR valve is the culprit of your car troubles or not.
It is important to carry out the injection pressure regulator (IPR) valve test first before changing the IPR valve. The reason? The problem with your engine might not be the IPR valve but some other issue related to the Powerstroke engine. For instance, when the ICP sensor is faulty, you might encounter similar symptoms as when the IPR valve is faulty.
Ford 6.0L Powerstroke Injection Pressure Regulator valve failure symptoms
Here are some of the symptoms of a faulty IPR valve.
Unstable, Rough, Poor Idle:
Engine idling is great when the idling is smooth. You’ll easily operate some of the basic systems in your car. For instance, great idle leads to easy operation of your car’s cooling system, power steering, and electrical system. Idling occurs when you let your engine run, but the car is off gear, or the accelerator is off. When there’s a problem with the IPR valve, it becomes difficult to run a smooth idle. Instead, what you get when you attempt the vehicle idle is that your tachometer needle starts to jump around in a not-so-steady way. Poor or rough idle also manifest when your vehicle’s engine keeps rising and falling while idling, or it becomes difficult for your vehicle to have a steady rotation rate.
Another symptom you’d experience when your IPR valve is faulty is your car stalls. This happens when your engine abruptly stops working and turning. Although it happens accidentally, car stalling can be dangerous and is quite stressful. For example, you could be driving on a busy road, then, all of a sudden, your engine just stops operating immediately. When this happens consistently, you might want to check the IPR valve as it might be the culprit.
Crank but No Start:
When your car cranks but doesn’t start, it could be as a result of certain things like zero fuel in the fuel tank, etc. however, if every other thing seems fine and you experience this symptom alongside some of the other symptom of IPR valve failure, then you already know who’s the culprit.
When related to the IPR valve, the injectors tend to surge when you accelerate. If you notice this symptom, get ready to take your vehicle to your mechanic.
Other symptoms of bad IPR valve include random surging (this often happens because of the low power to the IPR), your vehicle might crank for a long time before it starts, etc. when your vehicle cranks for a while before it finally starts or it becomes difficult to start your car when the engine is hot, don’t let sleeping dogs lie in this case. Instead, perform an IPR valve test to be sure the IPR is the problem. If the IPR valve is bad, take it to your mechanic to get it replaced. If you’re trying to save money, stick with us to see how the IPR valve is replaced.
6.0L Powerstroke Injection Pressure Regulator Valve Replacement
Replacing a 6.0L Powerstroke Injection Regulator valve is not something just anyone can pull off. Frankly, you have to either be a skilled mechanic or someone who takes it as a hobby and has the intermediate skill level for these things. As a beginner in the Powerstroke fixing field, you would likely get confused attempting to replace the IPR valve in your Powerstroke engine. Hence, it’s best to entrust the responsibility to an expert. Also, it would only take two hours to get the IPR valve replaced.
To remove the IPR valve, you’ll need the IPR socket and a 3/8’’ ratchet. The fastest route to reaching the IPR valve is to reach from under the vehicle. It makes it easier for you. However, you can also reach it from the top. If you reach the IPR from the top, you’ll need to take out quite a few components. For example, you’ll need to get the turbo, cab, etc., out of the way to get to the IPR valve. However, you choose to get to the IPR valve and ensure that you take out the heat shield that protects the IPR.
Once you reach the IPR valve, slide the IPR socket into the old and faulty IPR valve. It would help you make it loose so that you can twist it out. Then, put in your new IPR valve. Also, don’t forget to reinstall your heat shield.
A faulty IPR valve can eventually damage your car. So once you notice 6.0L Powerstroke Injection Pressure Regulator valve failure symptoms, and you start to suspect that the IPR valve might be the issue, do not hesitate to get it checked and fixed.
If you know how these things work, you can fix it yourself to save you money. For example, with a great scan tool from amazon, you can run a 6.0L Powerstroke IPR valve test.
Once the problem has been verified, you can replace your IPR valve with a new one. However, if 6.0L Powerstroke IPR valve symptoms persist, you might want to drive your vehicle to a mechanic to determine what the problem is.
