What Makes This 7.3L Powerstroke Years Worth Avoiding? (Common Problems)
This particular engine has been known to experience a number of common failures, which can be attributed to a variety of causes. Looking into the issue more closely, it appears that some of the most prevalent causes of 7.3l Powerstroke failure include inadequate fuel delivery, clogged air filters, worn out injectors and pistons, and cooling system issues. Further research is needed in order to determine if other factors are also at play.
1. Failure Of The CPS (Camshaft Position Sensor)
CPS (Crankshaft Position Sensor) was a major problem and frequent area of failure in Powerstroke 7.3l engines. CPS is an electronic device that monitors the position of the crankshaft to ensure proper timing in diesel engines. This sensor had a tendency to malfunction or become defective, leading to engine stalling, rough idling, and other malfunctions which could ultimately result in costly repairs if not addressed quickly.
If a 2002 Powerstroke truck is exhibiting difficulty in starting or stalling while driving, the most likely cause is a faulty crank position sensor. Replacing the stock CPS is normally an effective and straightforward remedy for this problem. It should be noted that proper diagnostic tests must be conducted to ensure that other issues are not present and contributing to this matter.
2. Leak In The Fuel Filter Housing
The 7.3L Powerstroke is a reliable engine, however it has one minor failure point. This occurs when the fuel filter housing or fuel bowl made of aluminum develops cracks, leading to fuel leaks. This can lead to further damage to the engine if not addressed promptly and properly.
The heating element in the filter house can short out, resulting in a no-start condition. Further, due to wear and tear over time, the plastic cap on the filter house may become cracked and cause fuel leakage. Companies must take proactive steps to inspect these components regularly in order to prevent any issues from arising.

3. Leaks In The Turbocharger Up-Pipe
The 7.3l Powerstroke is known to suffer from yet another failure point: a turbocharger leak in the up-pipes. This can lead to a decrease in boost and an increase in temperature of exhaust gas, both of which can greatly reduce the efficiency of this engine. It is essential that such leaks are identified and addressed as soon as possible to prevent further damage or performance issues.
4. EBPV Failure
The 2001-2003 Powerstroke 7.3L was notoriously prone to EBPV failure, which can have a detrimental effect on the engine’s performance. The primary function of the EBPV, or exhaust back-pressure valve, is to regulate temperature and quickly return the engine’s operating temperature to its normal state. If your vehicle has encountered EBPV failure, then deleting the EVP is one commonly offered solution for resolving this issue.
Most vehicles manufactured within a certain year range were prone to having misfire or difficult start issues due to faulty electrical connections within the UVCH (under valve cover harness). If one takes a closer look, it is easy to see that these problems were largely caused by inadequate contact between glow plugs or injectors and the wiring. Thus, this kind of issue can be easily avoided if regular inspections are done on all electrical systems in order to detect any potential problems early on.
Between 1994 and 1997, Powerstrokes had two connections running into each bank, making troubleshooting the harness more time-consuming. However, from 1999 to 2003 this was changed so that only one connector ran into each bank, which made it easier for technicians to diagnose any problems with the wiring harness.
