DTC DETECTION LOGIC CHART

DTC No. Trouble diagnosis name (Trouble diagnosis content) DTC detecting condition Possible cause
P0102 MAF SEN/CIRCUIT-B1
[Mass air flow sensor (bank 1) circuit low input]
An excessively low voltage from the sensor is sent to ECM.
  • Harness or connectors (The mass air flow sensor (bank 1) circuit is open or shorted.)
  • Intake air leaks
  • Mass air flow sensor
P0103 MAF SEN/CIRCUIT-B1
[Mass air flow sensor (bank 1) circuit high input]
An excessively high voltage from the sensor is sent to ECM.
  • Harness or connectors (The mass air flow sensor (bank 1) circuit is open or shorted.)
  • Mass air flow sensor
P010C MAF SEN/CIRCUIT-B2
[Mass air flow sensor (bank 2) circuit low input]
An excessively low voltage from the sensor is sent to ECM.
  • Harness or connectors (The mass air flow sensor (bank 2) circuit is open or shorted.)
  • Intake air leaks
  • Mass air flow sensor
P010D MAF SEN/CIRCUIT-B2
[Mass air flow sensor (bank 2) circuit high input]
An excessively high voltage from the sensor is sent to ECM.
  • Harness or connectors (The mass air flow sensor (bank 2) circuit is open or shorted.)
  • Mass air flow sensor
