LBZ po540 code

[Loren]

hi I have an 07 3500 dual tank Duramax LBZ with a check engine light for the air intake heater I understand the heater can maybe be shut off with an EFI live?

Can’t shut it off on a cummins lbz. No tuning for that.

Let’s try make model year one more time to make sure we are talking about the right engine here

Sorry about that I have a Duramax and a cummins

Okay guys sorry but I posted this forum in introductions not tuning so I have a 2007 Duramax LBZ 3500 and I have a check engine light for the air intake heater I understand it could possibly be shut off with EFI live so I could not get that light anymore?

It can.

Merged your two threads.

Fixing the grid heater will also clear the code too
