How to deal with the Warn light of the Sinotruk engine?

[VanMaggie]

But there is no abnormality in driving, it may just be a sensor failure. In this case, you can continue driving temporarily, but it is best to drive at medium and low speeds. When the intake hose is removed and cleaned, the intake flow sensor detects the difference between the flow and the engine's intake volume, generating a temporary fault code, which can be cleared. If there is a real fault, it is necessary to investigate and repair according to the fault code.

I drove trucks for 15 years, and whenever the engine warning light came on, I never took it lightly. First, I would immediately pull over, turn off the engine, wait a few minutes, and then restart it to see if the light was still on. If it remained lit, I definitely wouldn’t continue driving on the highway—it could be a fuel injection or sensor issue. I’d check if the fuel cap was tightened properly and whether there was enough fuel, as sometimes a loose cap could trigger the warning. If all else failed, I’d drive straight to the nearest repair shop. They could use an OBD2 diagnostic tool to read the trouble codes and help pinpoint the exact issue. Remember to schedule regular maintenance—don’t wait until the warning light comes on to get it checked.
