DENSO Oxygen Sensor Unheated Direct Fit Lead

The DENSO Oxygen Sensor Unheated Direct Fit Lead line gives you a direct-fit replacement O2 sensor (air/fuel ratio sensor) for vehicles originally equipped with an unheated oxygen sensor. The sensor sits in the exhaust stream. It measures the oxygen content of the exhaust gas and sends that data to the engine control module. The ECM uses the signal to keep the air/fuel mixture correct for fuel economy, performance and low emissions.

Key Features:

• Direct fit design: The sensor is built to match the original equipment thread and connector style, so it installs in the factory location without modification.
• Unheated sensing element: It relies on exhaust heat to reach operating temperature, as the original sensor did.
• Integrated lead and connector: The pigtail lead and plug are matched to the application for a secure electrical connection.
• Original equipment quality: DENSO is a leading original equipment supplier of automotive sensors. It builds these sensors to deliver accurate, consistent readings.
• Emissions and efficiency: An accurate sensor helps maintain fuel economy and smooth engine operation. It also helps prevent check engine lights caused by a failing sensor.

A worn oxygen sensor can cause poor fuel economy, rough idle, hesitation, failed emissions tests or a check engine light. Replacing it with a DENSO direct fit sensor helps restore proper engine management feedback. Choose the variant with the lead style that matches your application.
