Trouble In Daewoo Lanos B1675 Possible Cause

The reason of Daewoo Lanos B1675 is system wiring, connectors, or other electrical components are also subject to failure. When this code is set, it is imperative that the transmission be checked prior to further vehicle operation.

Common Symptoms For Daewoo Lanos B1675

  1. The exhaust gas temperature sensor is of the temperature reactive resistor variety
  2. If the resistance level does not decrease with heat and increase as it cools, replace the sensor. If everything has checked out thus far, turn the key to the "ON" position and test for the presence of a voltage (and a ground signal) at the exhaust gas temperature/pressure (or heated oxygen) sensor electrical connector
  3. If either the reference voltage or ground circuits are open, use the digital volt/ohmmeter to check for continuity (disconnect all related control modules from the circuit before checking circuit resistance or controller damage may occur) and resistance in both circuits
  4. If the fuel shutoff switch and all system circuitry checks out, suspect a defective PCM (or other related controller)

Daewoo Lanos B1675 Troubleshooting

A sure sign of this is smoke or steam being emitted from underneath the hood. The ignition timing could be set incorrectly and will require adjustment. If, when looking under the hood, you notice that the drive belts appear loose, they need to be tightened or completely replaced. If there is a noticeable pool of fluid underneath the car, this could be a sign of the cylinder head gasket failing. That will be confirmed in the form of billowing smoke being blown from the exhaust system. Parts or components should not be replaced with reference to only a Daewoo Lanos B1675 DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
