Mack MP7, MP8 & MP10 Check Engine Light
Problem: Injector or turbo issues caused by debris or stiction
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.
