Walker 210-1122 Air Charge Temperature Sensor

Walker Air Charge Temperature Sensor for Mercedes-Benz

The Walker Products Air Charge Temperature Sensor monitors incoming air temperature through resistance changes so the engine computer can calculate fuel delivery with greater accuracy. For Mercedes-Benz C220, C280, C36 AMG, E320, S320, and SL320 applications, this Sensor Only part helps support smoother cold starts, cleaner combustion, and stable engine management.

Sensor Only Design

Walker Sensor Only products focus on the sensing element needed for precise engine data input. Part number 210-1122 is built as an air charge temperature sensor with a female circular connector, one connector cavity, one male terminal, and butt terminal type. That configuration supports direct signal transfer to the vehicle’s control system for accurate intake air temperature reporting.

• Air charge temperature sensor for engine management input
• Measures intake air temperature through resistance changes
• Supports fuel delivery calculations and combustion control
• Female circular connector with one connector and one terminal
• Walker part number 210-1122

Detailed Application Coverage

This sensor is used in Mercedes-Benz engine management systems where intake air temperature data is required for fuel and emissions control. It is listed for 1994 Mercedes-Benz C220 and C280, plus 1995 Mercedes-Benz C220, C280, C36 AMG, E320, S320, and SL320. If you are searching for a Walker 210-1122 air charge temperature sensor for Mercedes-Benz C220 or a Walker 210-1122 replacement for Mercedes-Benz E320, this part matches those applications.

Walker Products focuses on precision sensing components that help the engine computer respond to changing air conditions. Accurate air temperature input can improve cold-start behavior, reduce drivability issues tied to incorrect fueling, and support emissions compliance.

What It Helps Address

• Incorrect air temperature readings sent to the engine computer
• Hard cold starts caused by poor intake air data
• Fuel delivery errors that affect drivability
• Rough idle or hesitation related to sensor input
• Emissions concerns tied to inaccurate engine management data

Installation Notes

Verify connector shape, terminal style, and vehicle application before installation. This part uses a female circular connector with butt terminal type and one male terminal, so matching the existing harness connection is important. Confirm the sensor location on the intake or air charge circuit for your Mercedes-Benz C220, C280, C36 AMG, E320, S320, or SL320 before replacement.

Quality Assurance

Walker Products is known for engine management components built around precise signal control and OE-style application coverage. Part number 210-1122 is intended to restore accurate air charge temperature reporting for the listed Mercedes-Benz applications.
