2004 Volvo V70 L5-2.5L Turbo VIN 59 B5254T2SECTION Signal Too High
Diagnostic trouble code (DTC) information ECM-8410
Condition
Diagnostic trouble code (DTC) ECM-8410 is stored if the 5 volt supply circuit for the mass air flow (MAF) sensor, boost pressure sensor, air conditioning (A/C) pressure sensor, oil level sensor and fuel tank pressure sensor has a voltage higher than 6 V (high signal) or lower than 4 V (low signal) and the control module interprets it as a fault.
Substitute value
- None.
Possible source
Signal too high:
- short-circuit to battery voltage in the 5 volt supply cable
- Defective mass air flow (MAF) sensor
- Defective boost pressure sensor
- Defective air conditioning (A/C) pressure sensor
- Defective oil level sensor
- Defective fuel pressure sensor.
Signal too low:
- short-circuit to ground in the 5 volt supply cable
- Defective mass air flow (MAF) sensor
