Walker 210-1165 Air Charge Temperature Sensor

Walker Air Charge Temperature Sensor

The Walker 210-1165 Air Charge Temperature Sensor measures incoming air temperature through resistance changes so the engine computer can calculate fuel delivery more accurately. For Mitsubishi Lancer and Mitsubishi Mirage applications, this sensor supports cleaner running, improved cold-start behavior, and more consistent engine management.

Walker Sensor Only products focus on the sensing element itself for direct replacement needs. Part number 210-1165 is built for vehicles that use a female connector with an oblong shape, two male terminals, and a single connector interface.

Key Features

• Measures intake air temperature through resistance-based signal output
• Connector shape: oblong
• Connector gender: female
• Terminal type: spade
• Terminal quantity: 2
• Terminal gender: male
• Walker part number 210-1165

Detailed Description

The Walker 210-1165 sensor helps the engine control module determine the correct fuel strategy based on incoming air temperature. That signal matters during cold starts, warm-up, and normal driving because air density changes with temperature. In Mitsubishi Lancer and Mitsubishi Mirage applications, accurate air charge temperature input supports smoother operation and more stable fuel control.

This Sensor Only line is focused on the electrical sensing component, making it a practical replacement when the original air charge temperature sensor has drifted, failed, or is sending inaccurate readings. The Walker 210-1165 is listed for 2008-2011 Mitsubishi Lancer and 1997-2002 Mitsubishi Mirage.

This part cross-references no interchange numbers in the provided data.

What It Helps Address

• Hard starting in cold weather
• Incorrect fuel delivery caused by inaccurate air temperature readings
• Rough idle related to sensor signal errors
• Reduced fuel efficiency from poor engine temperature input
• Emissions issues tied to faulty intake air temperature data

Installation Notes and Tips

Verify the connector style, terminal count, and sensor location before installation. The Walker 210-1165 uses a female oblong connector with two male spade terminals, so matching the electrical interface is important for proper fitment. Confirm the vehicle application against the listed years before ordering.
