Common Ford 3.0 Powerstroke Problems and Solutions

Not every 3.0 liter Powerstroke engine has these problems, a few of them come with such issues. Here we’ve mentioned 5 common problems that are usually found in 3.0 Powerstroke engines.

We’ve broadly discussed the problems, how they affect the vehicle, what the symptoms are, how you can fix them, and how much that would cost you. The cost mentioned here isn’t accurate, but you can get an idea.

#1 – Loose EGR By-Pass Valve Flap Screws

Almost all the 3.0 powerstroke diesel engines in the 2018 – 2019 model year F-150s have loose screw issues in the EGR by-pass valve flap. This is why Ford recalled most of those vehicles and fixed the issue.

The Exhaust Gas Recirculation (EGR) valve is an integral part of the emissions control system. And anything wrong with it has a direct effect on the performance.

A loose flap can cause severe damage to other components of the EGR system such as the cooler, pipes, hoses, and even the valve itself.


When the EGR valve flap screw is loose, the engine won’t be able to deliver the power it used to before, plus, the fuel economy will be reduced.

Like these, there are a bunch of symptoms that indicate that something’s wrong with the EGR by-pass valve. Take a look at all of them –

  • Check Engine Light On: This is the very first symptom you’d see if there’s anything wrong in the engine.
  • Rough Idling: You might experience rough idles and also vibration when starting or driving the vehicle.
  • Increased Emissions: When the bypass valve screws are loose, it doesn’t allow the EGR valve flap to open and close properly which increases the emissions of nitrogen oxide (NOx).
  • Engine Losing Power: There are many reasons why an engine loses power, and a faulty EGR system is one of them. If you notice a couple of the above-mentioned symptoms and also feel the engine isn’t delivering the required power, then the EGR system is to blame.

Possible Fix

If the EGR is in good condition then tightening the loose screws should fix the problem. But if the EGR is damaged anyhow, then replacement is the only option.

However, depending on the type of damage, EGR can be repaired sometimes. For example, if the pipe or hose has a leak, then replacing that component should solve the issue.

Whatever it is, it’s best to go for the replacement, since that eliminates the chance of further issues.


The price of the EGR system depends on the vehicle model but to give you an idea, it should be between $400 – $1,000. And the service cost depends on what state you’re living in.

However, you might need to pay around $150 for the service. So, all together you’re looking at anywhere between $500 to $1,200. That’s for replacing the entire EGR unit.

#2 – EGR Clogging

Since the 3.0 Powerstroke has loose EGR bypass valve flap screw issues, that increases the chance of a damaged EGR valve. And that leads to EGR clogging.

Not only that, the EGR system can clog due to many other reasons as well such as failed DPF, using the wrong engine oil, etc.


  • Check Engine Light On: As said earlier, if there is anything wrong with the engine, the engine check light will be turned on.
  • Increased Fuel Consumption: The engine has to work harder than usual when the EGR is clogged. And this will increase fuel consumption.
  • Hard Idle: The vehicle will idle hard and sometimes it might even stall.

Possible Fix

Cleaning the EGR valve should remove the clog. But if the valve or any other part is damaged, then that’ll require replacement.


You’d be paying around $150 for cleaning the EGR valve. And around $400 for EGR valve replacement, including the service charge.

The price may vary depending on the availability of the part, the model year of the vehicle, and the state you’re living in.

#3 – Bad EGR Cooler

There are many reasons why the EGR cooler goes bad, and in the 3.0L powerstroke, it seems like the loose EGR flap screws are the culprit. The most common reason behind bad EGR coolers is carbon buildup. It clogs the cooler and restricts the usual flow.

Coolant contamination is another reason why EGR coolers go bad. Though not very common, corrosion can also prevent the cooler from functioning properly.


  • White Steam or Smoke: When the EGR cooler has any leak inside, the exhaust pipe will release white steam or smoke.
  • Engine Check Light: If the vehicle’s system detects any fault, it triggers the check-engine light.
  • Lowered Coolant Level: The coolant level going down sooner than usual is a sign that there are single or multiple leaks.

Possible Fix

If the EGR cooler has leaks, then repairing them should get the cooler in working condition. However, if the cooler has been clogged, or started to corrode, replacement is the only way out.


Repairing the leaks won’t cost much, $25-$75 should cover it. However, installing a new EGR cooler can be a bit costly. EGR cooler kit can cost between $250 – $550. Plus, the service cost.

#4 – Crankshaft Bearing Failure

Though crankshaft bearings don’t require attention at the initial phase, but with the 3.0 Powerstroke you need to be careful.

Some users have reported the premature failure of crankshaft bearings in the 3.0 Powerstroke. However, Ford did fix the issue later.

A failed crankshaft is one of the last things you would want because it’s expensive. And if the bearing failure isn’t detected early, then that might cost you the entire crankshaft.

The reason for bearing failure isn’t due to any defect in the bearings, it was due to low oil pressure.


  • Knocking Noise from Engine: The very first hearable symptom of bearing failure is ticking or knocking noise coming from the engine.
  • Oil Leak: Check the parking spot, if you see oil leaking from the engine, that’s a symptom of bearing failure.
  • Engine Vibration: When the bearings are worn out or damaged, the vehicle will vibrate when riding. It might misfire when starting and idle hard as well.
  • Increased Fuel Consumption: The fuel economy will decrease noticeably when the crankshaft bearings are damaged.

Possible Fix

If the bearings are damaged but the crankshaft is in good condition, then replacing the bearings will be enough.

But in most cases, when the bearing fails, it soon damages the crankshaft too. In such cases, repairing or replacing the crankshaft is the way to go.


As mentioned before, crankshaft repair and replacement are both very heavy on the wallet. On top of that, if that specific model isn’t available widely, that’ll make it more expensive.

Replacing the bearings can cost you between $1,500 – $3,000 and since it requires good skill and time, the service cost can be between $500 – $2,000.

#5 – DPF Clogging

The Diesel particulate filter (DPF) in most of the vehicles fails with time but in some of the 3.0 Powerstroke vehicles, it seems to get clogged faster than usual.

There are many causes that lead to premature DPF clogging, and carbon dust accumulating in the exhaust gasses is one of them.

However, we’ve nothing specific on what exactly causes DPF to clog fast in 3.0 Powerstroke.

A clogged DPF can be a big threat to the engine, as it makes the engine work harder.


  • DPF Warning Light: If your vehicle has DPF, then definitely there is a warning light on the dashboard. And if there is anything wrong with it, you’ll see the light coming on.
  • Poor Engine Performance: Clogged filter will not allow a proper air flow which won’t provide the engine with what it needs. As a result, the engine will not perform well.
  • Reduced Fuel Economy: The engine works hard when the DE filter is clogged. And that results in higher fuel consumption.

Possible Fix

In most cases, cleaning the filter removes the blockage and the engine begins to perform well. But if the DPF has been clogged for a long time and it has been damaged, then replacement is necessary.


The price of DPF cleaning varies depending on the service provider and the state you’re living in. You might need to pay between $150 to $300. And replacing the entire DPF can cost between $4,000 – $8,000.

#6 – EGT Sensor Failure

Failed EGT sensor is a very common problem in V8 Powerstroke engines, though not as much as V8, 3.0 Powerstroke is also prone to EGT sensor failure.

There are many reasons behind EGT sensor failure, the most common ones are, exposure to heat, a clogged diesel particulate filter, turbocharger malfunction, and oil contamination.


  • Engine Noise: When the EGT sensor isn’t working fine, the engine might make a knocking or ticking noise.
  • Reduce Fuel Efficiency: The engine will start to consume more fuel since it’ll be working more than usual.
  • Failed Emission Test: A vehicle with a failed EGT sensor will not pass the emission test.

You should also see the check engine light on and the fault code. Look for the following codes, they all indicate EGT sensor issues.

  • P0544
  • P2031
  • P2032
  • P2033
  • P2084
  • P242A
  • P242D
  • P2471

Possible Fix

EGT sensors aren’t expensive, plus, installation doesn’t take very long. Therefore, it’d be wise to replace the sensor instead of repairing it. However, if the mechanic says repairing would be a good option, then opt for that.


Depending on the availability and model year of the vehicle, an EGT sensor can cost between $50 – $180. And service costs can be around $50.
