DENSO Auto Parts Oxygen Sensor P/N:234-4375
DENSO Auto Parts 234-2011 oxygen sensor for the 1993-1994 Lexus LS400 V8 4.0L senses the oxygen left in the exhaust after the catalytic converter. This DENSO Auto Parts oxygen sensor is an unheated, two-wire, direct-fit design.
A check engine light or poor fuel economy can mean the downstream oxygen sensor is worn, though a failing catalytic converter or damaged sensor wiring can be behind the same signs, so find the cause before you replace it.
This is a direct-fit downstream oxygen sensor for the 1993-1994 Lexus LS400 V8 4.0L, which takes one. The listing is a single sensor. DENSO makes and tests its oxygen sensors to OE standards.
