DTC P0130 Oxygen Sensor Circuit Malfunction (Bank 1 Sensor 1)


DESCRIPTION

The heated oxygen sensor is used to monitor oxygen concentration in the exhaust gas.
The ECM uses the heated oxygen sensor information to regulate the air-fuel ratio and keep it close to the stoichiometric air-fuel ratio. This maximizes the ability of the Three-way Catalytic Converter (TWC) to purify the exhaust gases.
The heated oxygen sensor generates an output voltage between 0.1 V and 0.9 V in response to the oxygen concentration in the exhaust gas.
The heated oxygen sensor output voltage changes dramatically in the vicinity of the stoichiometric air-fuel ratio.
If the oxygen concentration in the exhaust gas increases, the air-fuel ratio is lean and the heated oxygen sensor output voltage to the ECM drops below 0.45 V. If the oxygen concentration in the exhaust gas decreases, the air-fuel ratio is rich and the heated oxygen sensor output voltage to the ECM increases to above 0.45 V.
The heated oxygen sensor is more efficient when heated. When the exhaust gas temperature is low, the sensor cannot generate useful voltage signals without supplementary heating. The ECM regulates the supplementary heating using a duty cycle approach to adjust the average current in the sensor heater element.

DTC No.
DTC Detection Condition
Trouble Area
P0130
Heated oxygen sensor output voltage is below 0.45 V for 75 seconds or more (1 trip detection logic).
  1. Open or short in heated oxygen sensor (sensor 1) circuit
  2. Heated oxygen sensor (sensor 1)
  3. ECM
HINT:
  1. The internal resistance of the heated oxygen sensor (sensor 1) cannot be measured using a tester.
  2. Sensor 1 refers to the sensor closer to the engine assembly.
  3. The output voltage of the heated oxygen sensor and the short-term fuel trim value can be read using the intelligent tester.

MONITOR DESCRIPTION

After the engine is started and the temperature of the heated oxygen sensor element is presumed to have reached the activation temperature, if the output from the heated oxygen sensor is below a set value, the system forces the air-fuel ratio to become rich. If the output from the heated oxygen sensor is below the threshold even after that, the ECM determines that there is a malfunction. The ECM then illuminates the MIL and stores a DTC.

INSPECTION PROCEDURE

HINT:
Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
