J.C. Whitney JRK96090002 Heated Downstream Oxygen Sensor 4-Wire 2.4L OEM Replacement

The J.C. Whitney JRK96090002 is a direct-fit, OEM replacement downstream oxygen sensor designed for select Kia vehicles equipped with the 2.4L engine. This heated, 4-wire O2 sensor restores proper exhaust monitoring function after the catalytic converter, helping the engine control module (ECM) regulate fuel trim and emissions output accurately.

A faulty downstream oxygen sensor can trigger check engine lights, reduce fuel economy, and cause emissions test failures. This direct-fit replacement is engineered to match original equipment specifications, making installation straightforward with no wiring modifications required.

Key Features:

• Direct-fit OEM replacement — no splicing or wiring adapters needed
• Heated sensor design — reaches operating temperature quickly for faster closed-loop operation
• 4-wire configuration — dedicated heater circuit wires plus signal and ground
• Downstream (post-catalytic converter) position — monitors catalyst efficiency for emissions compliance
• 2.4L engine application — precision-matched to factory specifications
• Threaded mounting style — installs into existing bung using standard O2 sensor socket

Backed by J.C. Whitney's commitment to quality replacement parts, the JRK96090002 is a reliable, cost-effective solution for restoring your vehicle's emissions and fuel management system to factory performance.
