Cummins ISX & ISB Check Engine Light
Cause: Injector or turbo issues caused by debris or stiction
Solution: Use a scan tool to look for codes for injector or turbo issues. If an injector or turbo code is set, use one treatment of Stiction Eliminator and one treatment of Diesel Extreme. If another code is set, contact one of our diesel experts.
If you have access to a tool, scan for codes described above. If you don’t have your own scan tool, take the truck to a mechanic.
Codes dealing with injector or turbo performance are often caused by debris clogging the injector’s spool valve or the turbo bearing. Treatment with Stiction Eliminator and Diesel Extreme will clear this up.
If you have any questions, feel free to contact one of our diesel experts.
