Trucks are America’s obsession and one of the most popular trucks on the road today is the Ford truck and its 6.7 Power Stroke Diesel Engine.

The Ford F-150 is the best selling vehicle for the first half of 2022 and according to US News outranks most other full-size pickup trucks thanks in part to its spacious interior, impressive lineup of powertrains, and excellent towing and hauling capabilities.

Although the Ford F-150 is a popular truck, its 6.7 Power Stroke Diesel engine has experienced engine defects leading to many trips to the dealer.

The following are the 3 most common problems with Ford Power Stroke Diesel engine

• EGT Sensor Defect
• Injection Pump Failure
• EGR Cooler Clogging

Ford 6.7 PowerStroke Engine – History

Among Ford Motors’ diesel engine families, the Ford Power Stroke family is produced for heavy-duty applications. Originally introduced in 1994, the Power Stroke diesel engine was rebranded from Navistar International’s engines in order to compete against GM’s V8 Duramax Diesel Engine .

The Ford Power Stroke diesel engine’s durability and reliability is a popular choice for Super Duty trucks.

Ford claims its Power Stroke diesel engine “delivers a level of solid performance and dependability that truck owners just can’t find anywhere else.” 

Despite the automakers claim of solid performance, many Ford owners are complaining of defects with the Power Stroke Diesel Engines which we list below.

Ford Power Stroke Diesel Engine – The 3 Most Common Problems

1.  EGT Sensor Defect

EGT refers to Exhaust Gas Temperature.  EGT sensors measure exhaust gas temperatures and transmit this information to the ECM to control the after treatment system to reduce harmful emissions.

EGT sensor failure are among the most common problems with Ford 6.7 Power Stroke diesel engines. There are a total of 4 EGT sensors so there are a lot of potential failure points.  The most common failures seem to be in EGT sensors 12 and 13 (the middle two).

As a result of the failing EGT sensors, Ford extended the warranty to cover the EGT in the event of failure.

Here are a few symptoms of a malfunctioning EGT sensor

• Check engine light
• Fault code
• Failed emissions test

In most cases, the check engine light will be illuminated once the PCM detects an EGT sensor problem. Occasionally, a truck may go into limp mode if the PCM detects an EGT malfunction.

2.  Injection Pump Failure

The Bosch’s CP4 pump is used by Ford in its Power Stroke Diesel engine, and has a history of failure due to metal-on-metal wear or contact inside the pump.

One of the biggest concerns is that metal contamination, which is circulating around the engine, can damage many components of the fuel system, including injectors, regulators, and fuel lines.

The good news is Ford is aware of the metal contamination problem in its Power Stroke Diesel engine and is using a new pump on the 3rd generation 6.7 PowerStroke.

When a 6.7L Power Stroke injection pump fails, the following symptoms may occur:

• Severe loss of power
• Stalling
• Rough idle / stuttering
• Long crank or no start

In the event of a failed pump, your engine may stall or completely shut off due to a lack of fuel flow.

3.  EGR Cooler Clogging

EGR stands for Exhaust Gas Recirculation. The main purpose of the EGR is to reduce exhaust emissions by lowering the temperature of the exhaust.

The EGR recycles a portion of the exhaust gas back into the combustion chamber, where it combines with fresh intake air. By combining fresh air this lowers the amount of oxygen and increases the water vapor content to the combustion mixture which reduces the peak combustion temperature.   The end result is an exhaust of cooled water vapor instead of heated toxic fumes.

It is a common problem with EGR valves that, when they open, carbon deposits can build up and cause the EGR cooler core to become clogged.

It is not uncommon for some people to simply delete the whole EGR system when a defect or failure occurs.  This, however, may make passing emissions tests more difficult in the future.

EGR cooler kits are relatively inexpensive, usually costing less than 200 dollars, so replacing them is the best option.
