Check engine light on oxygen sensor

[monski21]

Hi mga sir's

Ask lang po ng help.

I have honda 2005 matic dimensional. Recently bigla bigla nalang lumalabas ung check engine ko.. pinabasa ko sa obd reader dati and ang code is 02 sensor fault nga. So ginawa ko nag order ako sa casa ng bagong oxygen sensor na napakamahal pla...wew. after na mariciv ko yun, pina install ko and delete codes na error.. pero after mga ilang days lumalabas pa din yung same error. Me idea kaya kayo mga boss?

Ito exact error code:

01-1 Heated 02 Sensor Voltage High
-Sensor 2

Thanks in advance

Did you change both the pre & post Cat sensors?

Check elsewhere.

An O2 sensor high-volt (assuming that the sensor is good) means that it is sensing a rich fuel mixture. Normally, when the computer receives a high-volt reading, it makes the engine run lean. If it still receives a high-volt, then there's likely a source of unchecked raw fuel coming in somewhere.

You may want to check for leaking fuel injectors or bad sparkplugs and/or ignition coil/coil packs next.

Ayt sige sir... Try ko din magpalit ng spark plug. Yung coil ba sir pano dina diagnose if me problem ung isa doon? Thanks

Also check the wiring harness of the oxygen sensor.
