Code P0141 2000 Honda Odyssey Description

The P0141 code for a 2000 Honda Odyssey indicates a malfunction in the O2 sensor Bank 1 Sensor 2 heater circuit. The O2 sensor, or oxygen sensor, is a crucial component in the vehicle's emissions control system. It measures the amount of oxygen in the exhaust gases and sends this data to the engine control module (ECM) to help adjust the air-fuel ratio for optimal combustion. The heater circuit in the O2 sensor is responsible for heating the sensor quickly to operating temperature for accurate readings.

Tech Notes for P0141 2000 Honda Odyssey

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 take 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 caused 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

When is the Code Detected?

Current amperage in the rear heated oxygen sensor heater circuit is out of the normal range.
