Delphi ES20133 Oxygen Sensor - Rear

Delphi ES20133 Rear Oxygen Sensor

The Delphi ES20133 is a heated rear oxygen sensor built for specific Mitsubishi Mirage and Dodge Colt applications. It uses a 4-wire design, a flat connector shape, and an 18 x 1.5 mm thread size for direct-fit replacement in confirmed rear sensor locations.

Key Features

• Heated oxygen sensor for rear position applications
• 4-wire configuration with flat connector shape
• 18 x 1.5 mm thread size
• Overall length: 620.0
• Package contents: oxygen sensor and instruction sheet
• OE-focused engineering backed by Delphi’s long history supplying automakers

Detailed Description

Delphi ES20133 is an emission control sensor designed for rear placement on select Mitsubishi Mirage and Dodge Colt models. It is listed for 1993-1996 Mitsubishi Mirage rear applications, including 1993 and 1996 Mirage without California Emission System and 1994 Mirage rear, plus 1993-1994 Dodge Colt rear with California Emission System. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Delphi’s OE heritage and supplier experience are reflected in the sensor’s fitment-focused design and construction.

What It Helps Address

• Check engine light related to rear oxygen sensor performance
• Incorrect exhaust oxygen feedback from a worn sensor
• Fuel trim issues caused by aging emission control components
• Failed emissions inspection tied to sensor malfunction
• Slow sensor response in rear O2 monitoring circuits

Installation Notes and Tips

Verify the rear sensor location, connector shape, and thread size before installation. Confirm whether the vehicle is equipped with California Emission System equipment, since fitment differs by application. Use the included instruction sheet during installation and compare the original sensor length and connector style to the replacement part before final tightening.

Quality Assurance

Delphi builds this oxygen sensor using OE-based experience developed over decades of supplying major automakers. The ES20133 is engineered for the listed Mitsubishi Mirage and Dodge Colt rear applications and is backed by Delphi’s aftermarket manufacturing standards.
