Product Details
Walker Products OE 250-24157 is part of the Walker Products OE line, which focuses on original-equipment-style replacement sensors for vehicle-specific fitment and ECU feedback requirements. This oxygen sensor is listed for 1995 Toyota Land Cruiser upstream, 1996-1997 Toyota Land Cruiser upstream, and 1996-1997 Lexus LX450 upstream. For shoppers searching for a 1995 Toyota Land Cruiser upstream oxygen sensor or a 1996-1997 Lexus LX450 upstream oxygen sensor, this part number provides a direct application match. This part cross-references no additional part numbers in the provided data.
What It Helps Address
- Check engine light related to upstream oxygen sensor performance
- Poor engine operation caused by incorrect exhaust feedback
- Increased fuel consumption from inaccurate air-fuel readings
- Higher exhaust emissions from a failing sensor
- Fault codes stored in the ECU for sensor-related issues
Installation Notes and Tips
Install this sensor in the upstream position before the catalytic converter on the listed Toyota Land Cruiser and Lexus LX450 applications. Verify connector shape, thread diameter, harness length, and mounting style before installation. Inspect the sensor wiring harness and connector for damage, since physical wear can shorten service life and affect ECU feedback.
