Truck was consuming coolant and you could smell it but can't see a leak then the service electronic throttle control light came on a few weeks later with a code reading P0402. This was a recall and has been replaced but was replaced before they had the proper fix for it. Dropped it off at dodge dealer this morning for further diagnosis.

At just 600 miles, the 2023 GMC Sierra 3.0 Duramax gave out a check engine light. The code reader displayed a P0402. The truck had a very strong fume odor. The truck was taken to service two times. GM engineering made tests on the truck and concluded that the truck needs to be reprogrammed. I have a case number established with GM (case number 9-9217617941). If the program is bad, why release the product to the public? See attached invoice for details. This issue is present on almost all LZ0 GMC trucks based on people I've met in forums. Please help us.

P0402: questions drivers ask

What does code P0402 mean?

P0402 is a generic OBD-II powertrain code. Its standard definition is "Exhaust Gas Recirculation Flow Excessive Detected". The code tells you which system set the fault, not which part failed; the owner reports on this page show what it meant in practice for 5 car models.

In NHTSA owner complaints, P0402 is mentioned most for the Ram 1500 (2), Ford Escape (1), GMC Sierra (1), across 5 models and model years 2014 to 2023. Popular models collect more reports because more of them are on the road.

Is there a recall for code P0402?

What should I do if my car shows P0402?

Write down when the code appeared and what the car did (warning lights, loss of power, noises, speed, weather). Check your VIN for open recalls at nhtsa.gov/recalls, ask a dealer or independent workshop to read the stored freeze-frame data before anyone clears the code, and keep the repair order. If the car loses power in traffic, stop driving it. CarHooq does not diagnose: these are owner reports and official recall notices, not repair advice.
