Keep the air charge temperature or coolant level sensor plugged in reliably with the Standard Ignition Air Charge Temperature Sensor Connector / Engine Coolant Level Sensor Connector, MPN S-1686. It drops in as a direct-fit replacement across a wide range of BMW and Mercedes-Benz models — including the 1995-1998 BMW 318I, 2001-2004 BMW 325CI, 1997-2003 BMW 540I, 1992-1993 Mercedes-Benz 300E, 2002-2004 Land Rover Range Rover, and 2004-2005 Chrysler Crossfire and Dodge Durango — with many more listed in the Buyer's Guide tab.
- Harness-side plug: provides the electrical connector that links the vehicle wiring to the sensor.
- Listed under two names: cataloged as both an Air Charge Temperature Sensor Connector and an Engine Coolant Level Sensor Connector — the same connector under both titles.
- Clean replacement: an alternative to splicing when the original connector is corroded, melted, or has loose or damaged terminals.
Over time a connector can develop green corrosion, brittle insulation, or spread terminals that lead to an intermittent sensor signal or a related trouble code. If a failed connector is the cause, this replaces it and restores a solid connection. Diagnose the circuit first to confirm the connector — not the sensor or wiring elsewhere — is at fault before replacing.
