Detailed Product Description

The Delphi ES10890 oxygen sensor is a heated type sensor featuring a 4-wire configuration that allows for faster warm-up times and improved sensor responsiveness. Its square connector shape ensures a secure electrical connection, minimizing the risk of signal loss or corrosion. The sensor’s thread size of 18 x 1.5 mm and overall length of 280.0 mm are designed to fit the rear position on compatible Honda models, including the CR-V and Insight. This sensor plays a critical role in monitoring exhaust gases and providing feedback to the engine control unit (ECU) to maintain efficient combustion and reduce harmful emissions.

Compatible Vehicles and Applications

This oxygen sensor is compatible with the following Honda models:

• Honda CR-V (rear oxygen sensor replacement)
• Honda Insight (rear oxygen sensor replacement)

It is intended for use in emission control systems where a heated oxygen sensor with these specifications is required.

Common Issues Addressed by the Delphi ES10890

• Check engine light triggered by faulty rear oxygen sensor
• Poor fuel economy due to incorrect air-fuel mixture readings
• Increased emissions and failed emissions tests
• Engine performance issues such as rough idling or hesitation
• Sensor signal degradation from wiring or connector problems

Installation Notes and Tips

• Ensure the vehicle is cooled down before sensor removal to avoid burns
• Use the correct 18 x 1.5 mm thread size socket for installation
• Do not over-tighten the sensor to prevent thread damage
• Verify the square connector is fully seated and locked
• Follow the included instruction sheet for proper wiring and torque specifications
