The mechanic I go to said I needed a p0141 oxygen sensor heater but what does that mean?2

Question

The check engine light is on and it has difficulties turning on.

Answer 1

The sensor is part of the emissions control system.The goal of the sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible.

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
