Compatible With 1994-1995 Mitsubishi Montero, N/A; 1989 Mitsubishi Montero, N/A; 1990-1994 Mitsubishi Eclipse, N/A; 1990-1994 Mitsubishi Mighty Max, N/A; 1990 Dodge Colt, N/A; and 1988-1989 Mitsubishi Mirage, N/A. This part number 1812221 is also referenced by ETS15, MD127984, and SU6643.

What It Helps Address

• Incorrect exhaust gas temperature readings sent to the ECM
• Engine management faults tied to sensor signal loss
• Driveability issues related to fuel, timing, or cooling control
• Emission control warning conditions caused by a failed EGT sensor
• Hard-to-diagnose exhaust temperature monitoring problems

Installation Notes and Tips

Verify the connector shape, terminal count, and wire count before installation. This sensor uses an oval female connector with blade terminals and a 2-wire layout, so matching the OE connector style is important for proper fitment. Confirm vehicle application by year, make, and model before ordering, especially on Mitsubishi Montero, Mitsubishi Eclipse, Mitsubishi Mighty Max, Mitsubishi Mirage, and Dodge Colt applications.
