NTK 24502 Oxygen Sensor - Upstream, Upstream Front or Upstream Rear

Direct Fit Oxygen Sensor for Toyota and Lexus

NTK Direct Fit Oxygen Sensor 24502 is a specific-fit replacement built for select Toyota, Lexus, and Geo applications from 1992-1995. It uses a non-heated, single-wire design with a 12.75-inch wiring harness, 18 mm thread diameter, and flange mounting for OE-style service on upstream positions.

Key Features

• Specific-fit oxygen sensor for direct replacement service
• Non-heated sensor design with 1-wire configuration
• 12.7500 wiring harness length for application-specific routing
• 18.000 thread diameter with flange mounting type
• OE-style fit, form, and function for select import applications
• NTK part number 24502 for catalog matching and lookup

Application Details

NTK 24502 is engineered for upstream oxygen sensor locations on select 1992-1995 Toyota Camry, 1992-1995 Toyota Celica, 1993-1995 Toyota Corolla, 1992-1993 Lexus ES300, and 1993-1995 Geo Prizm applications. It also cross-references Bosch 12102 for the same application. This part number is commonly searched as NTK 24502 oxygen sensor for Toyota Camry upstream, NTK 24502 for Toyota Celica upstream, and NTK 24502 for Lexus ES300 upstream.

What It Helps Address

• Faulty oxygen sensor readings that can trigger a check engine light
• Rough idle or inconsistent air-fuel feedback at the upstream sensor location
• Emissions test failures related to sensor performance
• Incorrect fuel mixture control caused by a worn sensor
• Driveability issues tied to aging OE-style oxygen sensor hardware

Installation Notes

Verify the sensor position, thread size, harness length, and connector routing before installation. This NTK oxygen sensor is listed for upstream applications only, including Bank 1 Sensor 1 and related OE-design positions shown in the fitment data. Confirm the vehicle’s emissions configuration and sensor location against the original part before replacement.
