Code Tech Notes

The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The control module monitors how long it takes the sensor to warm up and start sending an adequate signal. The code is triggered when the sensor is taking too long to warm up. Water getting inside the heated oxygen sensor connector can cause the heated oxygen sensor fuse to blow. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors. If the sensor and connector are OK, replacing the O2 Sensor 1 usually takes care of the problem.

Code P0141 Acura Description

A heater for the zirconia element is embedded in the Secondary Heated Oxygen Sensor (Secondary HO2S (Sensor 2)), and it is controlled by the Powertrain Control Module (PCM). When activated, it heats the sensor to stabilize and speed up the detection of oxygen content when the exhaust gas temperature is cold. If the Secondary HO2S (Sensor 2) heater draws other than a specified amperage, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
