Product Details

This Walker coolant temperature sensor is built to report engine coolant temperature accurately so the ECM can adjust fueling, ignition timing, cold start enrichment, and radiator fan operation. The sensor uses a blade terminal design with a rectangular female connector and no wiring harness included. Its OE-style calibration helps maintain proper communication with factory engine management systems across supported Jeep, Dodge, and Chrysler platforms.

Walker Products Full Service Kit coverage is aimed at service technicians and DIY repairs that require a direct replacement for a failed coolant temperature sensor. Part number 211-91074 is a practical choice when diagnosing temperature-related drivability concerns on Jeep Cherokee and Jeep Wrangler models, as well as Dodge Journey and Chrysler 200 applications.

Common Issues This Sensor May Address

• Check engine light related to coolant temperature signal faults
• Hard cold starts or extended warm-up behavior
• Incorrect fuel mixture from inaccurate temperature input
• Erratic radiator fan operation
• Poor fuel economy caused by faulty ECM temperature data

Installation Notes and Tips

Verify connector shape, terminal count, and vehicle application before installation. Inspect the cooling system connector and surrounding harness for corrosion, damaged terminals, or coolant contamination before installing the new sensor. Because no wiring harness is included, reuse the existing vehicle connector and confirm a secure electrical connection after installation.

For fitment reference, this part fits 2019-2021 Jeep Cherokee, 2018-2021 Jeep Wrangler, 2009-2020 Dodge Journey, 2007-2017 Jeep Compass, 2007-2017 Jeep Patriot, 2011-2014 Chrysler 200, 2008-2014 Dodge Avenger, 2007-2012 Dodge Caliber, and 2007-2010 Chrysler Sebring.
