OBD-II DTC P1435 – EGI Mini – MAF Failed Open Circuit

DTC P1435 meaning

DTC P1435 refers to a diagnostic trouble code indicating a failure in the Engine Control Module (ECM) related to the Mass Air Flow (MAF) sensor circuit. Specifically, it signifies that the MAF sensor is reporting an open circuit condition, which means that the ECM is not receiving the expected voltage or signal from the MAF sensor. This can lead to improper air-fuel mixture calculations, affecting engine performance and emissions.

Common symptoms associated with DTC P1435 may include:

• Check Engine Light illuminated
• Decreased engine performance
• Rough idling or stalling
• Poor fuel economy
• Increased emissions

DTC P1435 causes

Several factors can lead to the occurrence of DTC P1435, including:

• Faulty MAF sensor
• Damaged wiring or connectors in the MAF circuit
• Vacuum leaks affecting air intake
• Faulty ECM or software issues
• Contaminated MAF sensor

DTC P1435 seriousness

DTC P1435 is considered a serious issue as it can lead to significant engine performance problems and increased emissions. If left unaddressed, it may result in further engine damage or failure, as well as potential issues with vehicle inspections due to elevated emissions levels.
