P0053 or P0054

WARNING: This page is about a different variant/trim than selected.

The ECM determines the temperature by measuring the current flow through the heater and calculating the resistance. Based on the resistance, the ECM can predict the sensor temperature. The HO2S uses pulse width modulation (PWM) to control the heater operation. The ECM calculates the heater resistance on a cold start. This diagnostic will only run once per ignition cycle. If the ECM detects that the heater calculated resistance is not within the expected range, DTC P0053 sets for HO2S 1, or DTC P0054 sets for HO2S 2.
