O2 sensor circuit malfunction, Bank 1 sensor 2. Check the O2 sensor after the catalytic converter.
Unfortunately there is no fixing an O2 sensor. If the "check engine" light is on due to an O2 sensor, it can only be remedied by replacing the bad sensor.
You need to check the wiring to the O2.
It is recommended that you first read about how the O2 sensor works to familiarize yourself with the part. Perform a visual inspection of the sensor, confirm all connections are sound, and there are no cracks or other signs of physical damage to the sensor. Check your fuses to confirm that the O2 sensor is bad. If the fuse is good, you will require a voltmeter and test the sensor.
how do i know if the o2 sensor is bad. The check engine light would illuminate and the code(s) set would steer you to the faulty O2 sensor.
replace the bad sensor and it will turn off.
Check the O2 sensor(oxygen sensor) AFTER the catalytic converter
The check engine light would illuminate and set a code for the bad O2 sensor.
To test an abs sensor for a Lexus ES you will need to use a multimeter. The multimeter will determine if the abs sensor works or not.
if you disconnect the o2 sensor cable in the air intake then start the engine you would see the check engine sign turned on in the gauge panel. It is on then the sensor is working if off the the sensor may have problems
You can visit a local auto repair store to have them detect whether your O2 sensor is bad or not. They can normally do this for free in a few minutes. A bad O2 sensor would trip the check engine light to come on. The code retrieved would lead you to the failed O2 sensor.
The check engine code PO136 means the O2 sensor circuit malfunction
