P0141 2018 Honda CR-V Code - Secondary Heated Oxygen Sensor 2 Heater Circuit Malfunction

Quick Answer

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). Common causes include Faulty Secondary Heated Oxygen Sensor 2, Secondary Heated Oxygen Sensor 2 harness is open or shorted, Secondary Heated Oxygen Sensor 2 circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0141 2018 Honda CR-V 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).

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.

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the P0141 2018 Honda CR-V code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
