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.
