Code P0153 2014 Chevrolet Silverado Description
The heating elements inside each HO2S heat the sensor to bring the sensor up to operating conditions faster. This allows the system to enter Closed Loop earlier and the ECM to calculate the air-to-fuel ratio sooner.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the HO2S 1 rich-to-lean or lean-to-rich average response time is greater than a calibrated value for greater than 60s.
