Lexus Gs300 O2 Sensors


Recommended Posts

Hello People,

I have a 1999 Lexus GS300 I ordered an Oxygen Sensor cause I have one that's gone bad Bank 2 Sensor 1, Ive gotten one ordered from Denso but I dont think it's the correct one it's part number is 234-4519. Any Ideas guys on the correct one if it's wrong?

Thanks

I´ve installed these types for a 2000 GS300:

Denso Before Catalytic Converter Oxygen Sensor - OE Replacement, 4-wire, 1998-2005 Lexus GS300, part: NP2344626

Denso After Catalytic Converter Oxygen Sensor - OE Replacement, 4-wire, 1998-2005 Lexus GS300, part: NP2344603

If you 're on it, maybe replace both.

U might also want to try resetting the computer by unplugging the black side of the battery for 5 minutes. (if u haven't already done that). Of course you're gonna lose all your presets.
