DENSO 234-5150 Air/Fuel Ratio Sensor Direct Fit Heated Wideband Sensor - 5-Wire O2

The DENSO 234-5150 is a direct-fit, heated wide-band air/fuel ratio (AFR) sensor engineered to OE standards. Featuring a 5-wire design and a 20.47-inch wire length, this sensor installs as a precise drop-in replacement with no modification required.

As a wide-band oxygen sensor, this unit continuously monitors the air-to-fuel mixture in the exhaust stream across a broad range of driving conditions, sending real-time data to the engine management computer for precise fuel delivery adjustments. This results in improved fuel efficiency, reduced emissions, and extended catalytic converter life.

Key Features:

• Wide-band technology — measures air/fuel ratios from approximately 12:1 to 19:1 for finer fuel management control
• 5-wire heated design — reaches operating temperature quickly for accurate readings from cold starts
• Direct fit replacement — thread-in, screw-in mounting with M18 thread size and 22mm (7/8 in.) hex
• 20.47-inch wire length — matches OE harness routing for a clean, factory-correct installation
• OE-grade construction — manufactured and tested to the same standards as original equipment
• Planar zirconia sensing element — provides fast response and long-term accuracy
