Replace the oxygen sensor after

9 Recently, the emission fault light has turned on, and the fault code P0141 has been cleared and turned on again, indicating that the 02 sensor heater has failed. Then the rear oxygen sensor was removed for inspection.
The emission fault light is cleared and turned on again several times
Fault adjustment code P0141 shows 02 sensor heater circuit fault
It shows that the 02 sensor is a rear oxygen sensor. It is on the exhaust pipe behind the three-way catalyst. This space is large and can be removed without using a 22mm special sleeve and a spanner wrench.
Pins 1-2 of the heating circuit of the sensor in this car are used. Use a multimeter diode to shift on and off to show open circuit. If the resistance shift value is not displayed, it means that the sensor is dead.
So Omnipotent placed an online order to buy sensors and also bought some thread anti-seizure glue
Immediately after arrival, multimeter diode shifts heater circuit on and off display channel
The resistance value of the resistance measurement shows about 10 ohms, which is normal
The tools used are very simple, including a 2.5-ton jack, a safety bracket, a triangular tree, a 300mm adjustable wrench and a shoelace
Triangle wood pad left rear wheel to prevent car slipping
Sensor jacked up behind right front wheel Safety bracket Double safety
The sensor screw was removed last time and measured. It is easy to remove this time
The new plug buckle card is not in the original card hole, and it is fixed with a universal cable tie, as long as it is firm.
Eliminate fault lights
fault was solved
