Is there a way to stop EGR delete on LBZ?

Is there a way to stop EGR delete on LBZ?

If they added the delete EGR plate then on an LBZ you can use the Fingerstick to stop most codes. It will not stop all. Most have had good luck and a few have a code that pops that the fingerstick does not block. Here one needs to use a tuner that can do EGR delete tuning.

What causes a failure code on an EGR system?

Another common problem causing failure codes in this system is that the tip of the valve will become irregular shaped from carbon deposits. When this happens it no longer creates a perfect seal. This can allow exhaust gas to continue to flow when not called for by the computer. An example would be at engine idle or when the vehicle is cold.

How to clean a blockage in the EGR valve?

You will need to clean the EGR valve of the blockage using the following steps: 1 Disconnect battery 2 Remove sensors or clips 3 Loosen bolts holding the EGR valve 4 Use a EGR or Carburetor Cleaner to spray the valve and hoses 5 Reconnect the battery More …

What should I do if my EGR light is not working?

The repair of this condition is removal of the EGR valve and inspection of the passageway to check for a blockage. Each model vehicle has different procedures for clearing the passageway due to many different configurations of the system. Some Fords have a removable tube.

What happens when I block off the EGR on a LBZ?

This circuit modifies the MAF signal to the computer on the LLY and LBZ engines (Not LB7, Not LMM) to expected levels when the EGR is blocked off, modified or a big free flowing exhaust system (removing the cat) causes the ECM to set an EGR code and display the check engine light / service engine soon. In mid 2004 the LLY series was released.

What happens when I delete the EGR code?

Once the EGR is deleted you will receive an EGR code but that code can be disabled with the Duramax Tuner Spade which is head and shoulders above the PPE. It sounds like you now have a mashup of systems. I would recommend installing this delete kit and programmer.

Why is the EGR code popping on my diesel engine?

For the code possible the grid heater is bad if the power wire is connected and has voltage on cold engine startup day when needed. EFILive can disable the EGR as well stop the EGR codes from popping. Did you find the recommended reading relevant to this discussion?

What happens when the EGR is off on a Duramax?

As an example, an idling Duramax will flow approximately 37 g/sec of mass air with the EGR off. When the EGR activates (say 10% duty cycle) the resultant change in flow will show approximately 27 g/sec of mass air. This is because the engine is now receiving part of its air flow from the recirculation of exhaust.
