DTC DETECTION LOGIC AND CONDITIONS
DHU010200000S03
•The following DTCs have been adopted.
—P2009, P2010, P2016, P2017, P2067, P2068, P2102, P2103
•The following failure detection conditions are summarized information.
Fuel Gauge Sender Unit (Sub)
P2067 Fuel gauge sender unit (sub) circuit low input
•The PCM monitors the fuel tank level and input voltage from the fuel gauge sender unit (sub) when the engine
is running. If the input voltage is less than 0.78 V and fuel tank level is full, the PCM determines that the fuel
gauge sender unit (sub) circuit input voltage is low.
P2068 Fuel gauge sender unit (sub) circuit high input
•The PCM monitors the fuel tank level and input voltage from the fuel gauge sender unit (sub) when the engine
is running. If the input voltage is more than 4.9 V and fuel tank level is empty, the PCM determines that the fuel
gauge sender unit (sub) circuit input voltage is high.
APV Control
P2009 APV motor control circuit low input
•The PCM monitors the APV motor control current when the engine is running. If the control current is less than
0.1 A, the PCM determines that there is an APV motor control circuit malfunction.
P2010 APV motor control circuit high input
•The PCM monitors the APV motor control current when the engine is running. If the control current is more
than 10 A, the PCM determines that there is an APV motor control circuit malfunction.
APV Position Sensor
P2016 APV position sensor circuit low input
•The PCM monitors the input voltage from the APV position sensor when the engine is running. If the input
voltage is less than 0.2 V, the PCM determines that the APV position sensor circuit input voltage is low.
P2017 APV position sensor circuit high input
•The PCM monitors the input voltage from the APV position sensor when the engine is running. If the input
voltage is more than 4.8 V, the PCM determines that the APV position sensor circuit input voltage is high.

Throttle Actuator Control Circuit
P2102 Throttle actuator power supply line circuit low input
•The PCM monitors the input voltage from the drive-by-wire relay when the PCM turns the drive-by-wire relay
on. If the input voltage is less than 5.0 V, the PCM determines that the drive-by-wire relay control circuit
voltage is low.
P2103 Throttle actuator power supply line circuit high input
•The PCM monitors the input voltage from the drive-by-wire relay when the PCM turns the drive-by-wire relay
off. If the input voltage is more than 5.0 V, the PCM determines that the drive-by-wire relay control circuit
voltage is high.
