Delphi ES10840 Oxygen Sensor - Front

Front Heated Oxygen Sensor for Chrysler and Dodge

Delphi ES10840 is a heated oxygen sensor built for front-position applications on select Chrysler and Dodge minivans. It uses a 4-wire design, a square connector, and an 18 x 1.5 mm thread size for direct replacement service on listed vehicles.

Key Features

• Heated oxygen sensor for front exhaust placement
• 4-wire configuration with square connector shape
• 18 x 1.5 mm thread size
• Overall length: 385.0
• Package contents: oxygen sensor and instruction sheet
• Delphi ES10840 built with OE experience and aftermarket application knowledge

Detailed Description

Delphi ES10840 is an emission control sensor for monitoring exhaust oxygen content at the front position. It is compatible with 2001-2003 Chrysler Town & Country, 2001-2003 Chrysler Voyager, 2001-2003 Dodge Caravan, and 2001-2003 Dodge Grand Caravan, making it a direct-fit choice for front oxygen sensor replacement on these vehicles. Delphi draws on OE heritage and supplier experience with major automakers, and that engineering background is reflected in the sensor design and application coverage.

This part cross-references Bosch 13709 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings from a worn front sensor
• Reduced fuel control caused by slow sensor response
• Emission test failures tied to faulty exhaust feedback
• Driveability issues linked to inaccurate exhaust oxygen measurement

Installation Notes and Tips

Verify the connector shape, wire count, thread size, and front position before installation. Compare the removed sensor to Delphi ES10840 to confirm length and connector match, and follow the included instruction sheet during replacement. Always inspect the harness and exhaust bung threads for damage before installing the new sensor.

Quality Assurance

Delphi applies OE experience and supplier knowledge from its work with leading automakers to aftermarket parts like ES10840. That background supports consistent fitment and sensor construction for the listed Chrysler and Dodge applications.
