Factors about 7.3 Powerstroke engines
Underneath, we’ve combined a list of facts about 7.3 Powerstroke engines that you might be interested in.
Two million engines were manufactured.
Since it came out in 1994, Ford produced two million 7.3 Powerstroke engines for the next 10 years. The production ended in 2004 as new models joined the market and new technologies were employed. You can find this engine on heavy vehicles such as GM and Chrysler SUVs.
The engine came with a special injector system.
When it was released, it got increased attention in the automotive world. Ford introduced a Hydraulic Electronic Unit Injector to maintain power while keeping an acceptable level of emissions. Even though global warming was not a significant problem decades ago, it still had regulations for clean emissions.
Two different turbochargers were used throughout the production years.
From 1994 when it first came out, the 7.3 Powerstroke engine featured a Garrett TP38 Fixed Geometry Turbocharger, which ceased production in 1997. Two years later, Ford decided to introduce the Garrett GTP38 Wastegated Turbocharger. They used it until the production of the engine was interrupted.
Like all engines, the 7.3 Powerstroke had its problems.
Failure of the camshaft position sensor was the most common one reported by owners of vehicles with this engine. The sensor controls the camshaft and transfers the information to the central computer to regulate fuel delivery. Other known problems are the injector control pressure sensors and the leaky fuel filter housing.
If you can, avoid the 2001 and 2002 Powerstroke engines.
They feature more problems than the ones produced in different years. Significant changes at the beginning of the new millennium made this engine louder while also developing problems with the sensors. The introduction of powdered metal rods also significantly decreased the engine’s performance.
Specific trouble codes can inform you about issues with the engine.
There are trouble codes related to the 7.3 Powerstroke engine that will inform you about specific problems. They are:
P0603 – This code informs you there is something wrong with the Powertrain Control Module. It most likely failed the self-test that occurs every time you start your engine. This module controls essential systems in your car, so you should take this warning code seriously.
P1315 – When this code appears, it can indicate several malfunctions. The vehicle’s computer will generate this code when the 4th ignition coil is failing or has a poor electrical connection.
P1211 – Low oil levels or poor oil quality can generate this trouble code. There are some situations where the injection pressure regulator valve and Powertrain Control Module fail. It will lead to the trouble code P1211 being displayed.
P1280 – This specific trouble code appears whenever there is a problem with the Injection Control Pressure sensor. Most likely, the pressure is too low and out of range. It happens because the sensor is flooded with oil, and you will have to clean it up.
P1247 – Another code is P1247, which warns you about several problems. The MAP hose might be damaged or faulty, but you should also consider a problem with the Powertrain Control Module. When the intake manifold presents leaks, this code is also displayed.
It has a specific oil type and capacity.
The recommended viscosity for the 7.3 Powerstroke engine is SAE 10W-30, which is ideal in conditions between -10 to 90 degrees Fahrenheit. For colder temperatures, use an engine block heater. The entire capacity of the oil tank is 15 quarts.
Although a heavy-duty engine, it has a reasonable fuel economy
A Ford F350 with a 7.3 Powerstroke engine has a fuel economy of 15-16 MPG. Other models have different results, where a 2002 Ford F250 gets a combined average MPG of 13.38. While these are heavy vehicles, the engines are more fuel-efficient.

The first 7.3 Powerstroke engine was manufactured in 1994 and was introduced on Ford’s popular F-series trucks. These vehicles came in manual or automatic transmission options, and the buyers could choose the one fit for them. This engine produced 210 horsepower and 425 lb-ft of torque starting from its first day. During the 10 years of production, this engine was favored by many.
The 7.3L engine was introduced with a turbocharger back in 1993. This is also when its internal parts were upgraded to resist the increased turbo pressure. However, the increase in power was not exceptional, and many people questioned this choice. But Ford returned the next year with their new 7.3 Powerstroke engine, which also featured a turbocharger with a direct-injection design.
To ensure maximum efficiency from your engine, you should change the oil and its filter once every 15,000 miles. The message center on your dashboard might display this indication earlier. Changing the oil whenever the system informs you is recommended, as the vehicle’s computer knows the situation in detail.
