What Is P2263 Code On 6.4 Powerstroke

What Does P2263 Code Means On 6.4L Powerstroke?

P2263 is one of the error codes of the 6.4L engine & it indicates problems with the fuel delivery system or turbocharger boost system. By definition, this code refers to Turbo/Super Charger Boost System Performance.

The supercharger or turbo creates its boost using exhaust pressure & fuel/air mixture. To control the exhaust pressure, the manufacturer determines a range & the exhaust pressure stays on that limit.

This exhaust pressure is monitored by the PCM (Powertrain Control Module) all the time. So, when the PCM detects exhaust pressure being high or low compared to the predetermined range – it stores the DTC P2263.

Your engine can get this code for various reasons besides the ICP (Injection Pressure Control) sensor being dirty/faulty. Here are the common causing factors of the error code P2263:

  1. Broken & Loosen Hose Clamps Causing Boost Leaks

How to Solve P2263 Error Code On 6.4L Powerstroke?

As the possibilities of getting P2263 are endless (sort of), there is no exact solution you can implement to fix it. However, you can try these well-known methods mentioned below & see if it works for you:

Check Hoses & Oil Supply Line

The first thing you should do is inspect the hoses & the oil supply line connected to the turbo. Check if you can find cracks & loose clamps. If so, consider replacing the hoses.

Do the same thing with the oil supply line. Chances are, you’re having one or several leakages in the oil supply line. Replace the oil supply line with a new one & the error code should be solved.

Check & Replace The Turbo

First, remove the turbo & inspect the bearing for leaks. If you get oil inside the bearing, the bearing is faulty. Repairing the turbo isn’t DIY work; replace it instead & save yourself some bucks of high labor cost.

You can also check other things such as – exhaust side of the turbo & turboshaft to spot any irregularity. If you find anything unusual, replace the turbo as an easy solution.

Check & Replace ICP Sensor

The ICP (Injection Control Pressure) sensor is located in a very vulnerable position. The electrical connector of the ICP sensor is often seen storing oil which causes the ICP sensor to malfunction.

First, remove the electrical connector from the ICP sensor. Inspect it thoroughly & see if there is any oil. Getting oil there is a clear indicator that the ICP sensor is faulty & needs to be replaced.

Check & Replace EGR Pressure Sensor

Last but not least, checking & replacing the EGR (Exhaust Gas Recirculation) Pressure sensor can lift the DTC P2263. Though the EGR works for reducing NOx emission, it can also contribute to getting the code.

Inspect your EGR pressure sensor line thoroughly. Check if any contamination or corrosion is causing any blockage. Don’t forget to check the electrical connector as well. If you find anything suspicious, replace the sensor.

How Much Does It Cost To Solve The Error Code P2263?

You may have one or several engine parts damaged & need to be replaced. In this way, measuring how much it will cost without inspecting the truck is very tough.

What you can measure is the labor cost if you’re getting professional help. Expect to pay $75 to $150 per hour, depending on your regional labor cost. On top of that, add the replacement parts prices too.

Common Mistakes While Solving The P2263 Code

Not checking the hoses & oil delivery pipe is the biggest mistake most users make while solving the P2263 code. Besides, beware of these common mistakes as well:

  1. Not Checking The Turbo Thoroughly Before Replacing
  2. Not Checking The Technical Service Bulletin Before Proceeding To Repair
