30-Day Free Returns: Shop with confidence. If the part doesn't fit or you’ve changed your mind, return it within 30 days in its original condition for a full refund.
6-Month Warranty: We stand behind our products. This sensor is covered by a 6-month limited warranty against manufacturing defects.
100% Genuine Quality: We provide authentic parts designed to meet or exceed OEM specifications for longevity and accuracy.
Wide-Band vs. Narrow-Band: This is a Wide-Band sensor (5 wires). It is not interchangeable with standard 4-wire sensors. Please verify your old sensor has 5 wires before ordering.
Upstream Position: In most applications, this sensor is used in the Upstream (Front) position (before the catalytic converter).
Anti-Seize: Denso sensors come with a factory-applied specialized coating on the threads. Do not add extra grease to avoid contaminating the sensor tip.
To ensure this sensor fits your truck, please verify the following three points:
Check Your Engine: This Denso 234-5176 is specifically designed for the 2.7L & 3.5L EcoBoost and the 5.0L V8 engines. It is the Upstream (Upper) sensor located before the catalytic converter.
Left vs. Right (Bank 1 vs. Bank 2): On F-150 V6 and V8 models, there are two upstream sensors. While this sensor fits both sides in most cases, we strongly recommend replacing both at the same time to ensure the ECU receives balanced air-fuel data.
5-Wire Wideband Technology: The 2015+ F-150 uses a sophisticated Wideband sensor to manage fuel economy. Do NOT attempt to use a cheaper 4-wire sensor, as it will cause immediate engine fault codes and poor gas mileage.
