DTC P0133: Linear O2 Sensor Circuit Slow Responsive (Bank 1 Sensor 1): DTC Detecting Condition
- DTC Description
The ECM monitors front oxygen sensor amplitude level and compares it to predetermined minimum amplitude value which could increase emission or disturb lambda control by the effect of ageing on the oxygen sensor.
The ECM sets DTC P0133 when the amplitude of oxygen sensor is equal to or less than minimum amplitude threshold. If same error code is set in the next driving cycle, the ECM illuminates the MIL.
