The P0031 code is a result of the bank 1 HO2S1 (pre catalytic converter heated oxygen sensor) heating element having low voltage. Heated O2 sensors have a seperate heater inside the sensor to get them to operating temperature quickly.
What does trouble code P0031 mean?
If your OBD-II scanner indicates an error code P0031, this means that you have an issue with your O2 sensor number one. For many vehicles, this is also known as an air/fuel ratio sensor.
What is a heater control circuit Bank 1 sensor?
What Does the P0030 Code Mean? Diagnostic Trouble Code (DTC) P0030 stands for “HO2S Heater Control Circuit (Bank 1, Sensor 1).” It may be triggered when your vehicle’s control module detects a fault in the heater circuit in oxygen sensor Bank 1, Sensor 1. Bank 1 is where cylinder number 1 is located.
What does the heater control circuit do?
This code is seen when the Engine Control Module (ECM) tries to control the heater control circuit for Bank 2 Sensor 1 and finds high voltage present. The heater is an integral part of sensor function that is used to heat the oxygen sensor to operating temperature until the vehicle warms up.
What is a heater circuit bank 1 sensor 2?
Bank 1 Sensor 2 is the oxygen (O2) sensor that’s in the middle of the catalytic converter or right behind the front catalytic converter (the converter that’s closest to the engine). Bank 1 Sensor 1 is the sensor between the engine and the catalytic converter.
How do you fix a heater control circuit?
Zitat von Youtube: Manifold. Visually check the oxygen sensors electrical connections wire harness and metal tabs for any damages. If the damages are found then replace the oxygen. Sensor.
How do you clean O2 sensors?
Zitat von Youtube: Take it out you know spray. It let it soak. Again you know rinse and repeat a couple of times try to get as much of the gunk out as possible. However you're very unlikely to be able to get.
Is there a fuse for oxygen sensor?
yes, there is a fuse for the o2 heaters. check all the fuses. it may also be a harness issue and needs to be checked as well.
What is heated oxygen sensor?
OBD II equipped vehicles use heated oxygen sensors. Heated oxygen sensors have an internal heater circuit that brings the sensor up to operating temperature more quickly than an unheated sensor.
What is an air-fuel ratio sensor?
The air-fuel ratio sensor monitors the oxygen content in the exhaust stream and sends data to the computer so that it can add or subtract fuel. If there is any problem with the sensor, it can send a bad or false signal to the computer which can throw off its calculations and cause it to waste fuel excessively.
Which 02 sensor is bank 1 sensor 2?
Zitat von Youtube: Usually on your exhaust monitor guys on the exhaust.
Where is the HO2S sensor?
The sensor is typically located on the passenger side of the car, mounted directly onto the exhaust pipe near the catalytic converter.
