DTC Detection Logic

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 sensor circuit is open or shorted.) (Sensor power supply 2 circuit is open or shorted.) Intake air leaks Mass air flow sensor Each sensor, connected with sensor power supply 2 circuit
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 sensor circuit is open or shorted.) (Sensor power supply 2 circuit is open or shorted.) Mass air flow sensor Each sensor, connected with sensor power supply 2 circuit
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 sensor circuit is open or shorted.) (Sensor power supply 2 circuit is open or shorted.) Intake air leaks Mass air flow sensor Each sensor, connected with sensor power supply 2 circuit
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 sensor circuit is open or shorted.) (Sensor power supply 2 circuit is open or shorted.) Mass air flow sensor Each sensor, connected with sensor power supply 2 circuit
