What Is P2263 Code On 7.3 Powerstroke – (With Fixing Guide)

As a veteran automotive technician, I can tell why the P2263 code 6.4 Powerstroke error shows. It’s mainly because of issues in the fuel delivery mechanism or turbocharger boost assembly.

Since the turbocharger boost depends on the exhaust pressure of the engine, it shows the p2263 code when it detects any unusual exhaust pressure.  

However, if your vehicle is really old, there might be other causes for the trouble code p2263 as well. Take a look at the common causes for this in brief:

S.LCommon CausesQuick Fixes
01.Problematic Exhaust Back Pressure-EBP sensorReplace or recondition the sensor.
02.Faulty Injection Control Pressure-ICP sensorMake sure no oil is stored in the ICP sensor. Or replace the ICP sensor.
03.Cracks in the oil supply lineFix the cracks and loose clamps.
04.Oil accumulation in the turbo and bearingRepair the turbo or replace it.
05.Blockage in the Exhaust Gas Recirculation-EGR pressure sensor lineCheck for any existing corrosion or blockage. Replace the EGR sensor.

Now, not being a professional mechanic, this might seem a bit overwhelming for you. However, I have laid down an easy guide on the p2263 code below. So, check it out!

What Is P2263 Code 6.4 Powerstroke

What Is P2263 Code on 6.4 Powerstroke?

Ford provides a Powertrain Control Module-PCM in its engines. The duty of PCM is to detect any inconsistency in the engine system.

Plus, Ford also made some Diagnostic Trouble Code-DTCs to define various errors in its engines.

Thus, when the PCM detects unusual behavior in the exhaust pressure or the fuel-air mixture system, it shows the code p2263. The “p” letter in the code stands for “Powerstroke”, and “2263” is just an error code terminology.

Note that causes and fixes of the error code p2263 are somewhat similar to P0603 Code 7.3 Powerstroke as well. It’s a commonly found error code in 7.3L Powerstroke engines.

6 reasons to Causes Code P2263 On 6.4 Powerstroke

There is a wide range of issues that can cause the p2263 code to show up. I already gave you a brief idea of these above. However, you should take a look at them in greater depth below:

#1- Problematic ICP-Injection Control Pressure sensor:

The job of an ICP sensor is to monitor the pressure of the fuel that is entering the engine injectors. So, if the ICP sensor is problematic, it can cause the DTC code p2263 to show up.

#2- Problematic turbocharger:

A turbocharger feeds compressed air into the engine so the engine can properly combust fuels. However, turbochargers can be a cause of error code P2263 if dirty or low-grade oil has contaminated it.

#3- Issue in the Boost Pressure Sensor-BPS

A testing report from engineers of Pierburg suggests that BPS in the turbocharger of an engine is responsible for monitoring air pressure and air-fuel mixture ratio.

Therefore, if this device is somehow damaged, it messes up the performance of the turbocharger. In turn, you might see the code P2263.

#4- Damaged hose clamps

The function of hose clamps in a 6.4 Powerstroke engine is to prevent all types of leaks (air or liquid). However, if the hose clamps are corroded, they can be the cause of accidental leaks in the engine.

This can also be the reason why your engine is showing the P2263 code.

#5- Damaged Exhaust Back Pressure-EBP Sensor

According to Dieselnet, a damaged EBP sensor will cause your vehicle to lose its fuel efficiency. However, EBP sensors can also cause major problems in the fuel delivery system.

Or, they can also get in the way of your turbocharger boost systems and prevent them from working properly.

Thus, EBP sensors can create actuator problems in the engine as well. So, they can be responsible for the p2263 code.

#6- Low engine oil level:

Although it’s not always the case, a low engine oil level can cause your engine to do all sorts of weird activities. Including making knocking, clunking, and grinding noises, according to a report by Bohnford.

And, if this condition persists for long, your turbocharger and fuel delivery system can get damaged permanently. Resultantly, the sometimes low engine oil level is also the cause of the P2263 code showing up.

What Are The Symptoms Of Code P2263 On 6.4 Powerstroke?

It’s really hard to pinpoint which exact symptoms your 6.4L Powerstroke engine will show before showing the P2263 code. However, some general abnormalities can indicate an upcoming P2263 error code:

  • Deteriorating boost pressure in the engine
  • Deteriorating acceleration performance
  • Weird and abnormal noises are generated from the engine. For instance, grinding, clunking, or knocking noises might occur in your engine.
  • Sudden shut down of the engine
  • Difficulty and delay in starting the engine
  • Huge amount of white smoke coming out of the engine exhaust
  • Surges in the engine when it’s idle
  • Melting of charge air cooler hose.

How To Fix P2263 Code on 6.4 Powerstroke?

Fixing the P2263 error code on the 6.4 Powerstroke engine is not a DIY job. That’s why I have suggested some general fixes to curb the problem of code P2263 from my own experience of decade-long automotive repairing.

So, pay attention below:

1. Replace old hose clamps and recondition the oil supply line:

The first and foremost step in solving any issues in a 6.4 Powerstroke engine is to replace any old or corroded hose clamps. Corroded hose clamps are usually responsible for leaks in the engine.

Plus, the oil supply line is directly responsible for some major engine failures. So, if your oil supply line is not maintained properly, I suggest that you recondition the oil supply line immediately.

2. Getting a new turbo:

Any leaks or damages in the turbocharger of an engine can damage the engine permanently. Plus, as I have already mentioned above, turbo is one of the major causes of P2263 error.

Moreover, as I have seen from my own experience, problematic turbochargers also cause P1280 code 7.3 Powerstroke engines.

This is why changing the old turbocharger is important. But, you should know that repairing the existing turbocharger is not an easy job that a non-expert can do.

So, getting a new turbo is the better option for you.

3. Discarding the problematic ICP sensor:

As I have already said above, problematic ICP sensors can be the culprit for why the P2263 error is showing for you. So, discard the ICP sensor and install a new one.

4. Getting a new EGR pressure sensor:

Sometimes, simply changing the EGR pressure sensor can lift engine error codes (such as the P2263 code). So, try doing that as well.

How serious is the code P2263 on 6.4 Powerstroke?

The P2263 error code is an extremely serious trouble code for old engines such as the 6.4 Powerstroke. If this error is not fixed as promptly as possible, your engine’s lifespan will deteriorate very fast.

How Much Does It Cost To Replace PCM?

A PCM-Powertrain Control Module in a car is practically a small size computer that computes and calculates the necessary data in the vehicle.

Now, in terms of replacement scope, you can’t really replace a single part or component of the PCM. Rather, if any IC or chip of your PCM is malfunctioning, you have to fully replace it altogether. Therefore, it can be quite costly to replace a PCM in the car.

Depending on the brand and manufacturer of the PCM you are willing to buy, replacing your faulty PCM with a newer one will set you back at least $800 to up to $1,500.

How Do I Reset My Powertrain Control Module?

The PCM reset is a relatively easy job. Simply, you need to open up the hood of your car and locate the PCM.

After that, you have to disconnect the “negative” cable of the PCM from the battery. That, in turn, will shut off the PCM. Next, you’ll have to wait for up to 15 minutes for the PCM to settle down. In the 15 minutes of wait time, any remaining current in the PCM will die down.

As a result, the PCM of your vehicle will not have any memory of the programming that was done before shutting it off.

Now, once you have waited for 15 minutes, you should reconnect the “negative” cable of the PCM to the battery again. This will restart the PCM, and in the process, your PCM will get reset.
