DTC Troubleshooting: P043E, P043F, P2DD9, P2DDA(3.0L Engine): Overview
- P043E: If the reference pressure of the EVAP leak check module is low, or if the difference between the reference pressures of the EVAP leak check module obtained twice is large, the PCM determines an abnormality and stores the DTC.
- P043F: If the reference pressure of the EVAP leak check module is high, the PCM determines an abnormality and stores the DTC.
- P2DD9: If the pressure fluctuation is large during the measurement of the EVAP leak check module reference pressure, the PCM determines an abnormality and stores the DTC.
- P2DDA: If the pressure fluctuation when the EVAP leak check module vacuum pump or the change over valve is switched is large, the PCM determines an abnormality and stores the DTC.
