Do you ever wonder if Toyota direct injection ( D4S ) System build up carbon? In this video we take a look at an in service Toyota D4S engine to find out if that is the case or not.
Toyota's D4S injection system uses both Direct and Port Injection. So in theory it shouldn't build up carbon. But does it?
In this video we have a 2017 Toyota Sienna with a 2GR-FKS engine which has Toyota's D4S System and we will find out if it does build up carbon or not.
I also share some tips on how to prevent carbon build, D4S System reliability and more.
