This part cross-references Standard Ignition ETS216 for the same application.

What It Helps Address

• Fault codes related to exhaust gas temperature sensor performance
• Incorrect exhaust temperature readings in diesel emission systems
• Driveability issues tied to DOC or DPF monitoring
• Emission control warning lights on supported Mercedes-Benz models
• Sensor replacement needs caused by heat and exhaust exposure

Installation Notes and Tips

• Verify the vehicle position and notes before ordering: right, left, or N/A applications vary by model and build date.
• Confirm the connector shape, terminal style, and thread diameter match the original sensor.
• Use the fitment notes for DOC, DPF, turbocharger, or before-DOC placement on the specific Mercedes-Benz application.
• Inspect the exhaust bung and wiring path before installation to ensure proper routing and seating.
