Check engine light triggered by a low fuel flashing light

Asked by May 13, 2018 at 01:53 AM about the 2005 Mercedes-Benz M-Class ML 350 4MATIC

Question type: Maintenance & Repair

Once in a while the low fuel light will start flashing and that leads to a check engine light. Retightening the gas cap and removing the positive battery cable will reset it. I have replaced the gas cap but this did not correct the problem. When removing the gas cap, there is pressure in the tank. Could this be a faulty senser or a bad wire connection causing this? Has anyone else had this problem?

The CEL might be on due an issue with the EVAP system. Scan for the codes next time the light is on to see what the problem is, why guess? Look up OBDii Codes. Your local auto parts tore will in most time scan your car for no charge. Post the 4 digit codes back here for more help.
