Injector FAQ
FAQ: What are the reasons for black smoke?
ERIKC Answer: rail pressure sensor signal drift
If the rail pressure sensor actually measures rail pressure lower than the actual rail pressure, then the amount of fuel that is sprayed out will be greater than the theoretical fuel injection amount. If there is more fuel, the same air will easily cause black smoke. Rail sensor pressure signal drift is common sensor failure or contact terminals abnormal. If you suspect a rail pressure sensor is faulty, replace the crossover experiment.
FAQ: What are the reasons for black smoke?
ERIKC Answer: water temperature sensor signal drift
The water temperature has a large correction for the amount of fuel injected. The lower the water temperature, the greater the amount of fuel injected. If the ECU detects that the water temperature is always low, the ECU will control the injector to inject more fuel. If you suspect that there is a fault in the water temperature, it is much simpler. After the engine runs for a while, the diagnostic instrument reads the water temperature signal to see if it is in line with the actual situation.
FAQ: What are the reasons for black smoke?
ERIKC Answer: atmospheric pressure sensor failure
Bosch ECU's atmospheric pressure sensors are integrated inside the ECU, and atmospheric pressure is used to correct the amount of fuel injected. If you suspect that the atmospheric pressure sensor is faulty, the first thing to check is whether there is any abnormality in the power supply ground of the ECU. After confirming, check the ECU.
