Walker 211-91031 Engine Coolant Temperature Sensor
Engine Coolant Temperature Sensor Overview
Walker Products 211-91031 is an engine coolant temperature sensor for Nissan and INFINITI applications that rely on accurate coolant temperature data for ECM control. It uses a 2-terminal blade connection with a rectangular female connector and a 12.0 threaded end diameter for direct-fit service on listed vehicles.
Built for real-time temperature reporting, this sensor supports proper fuel delivery, ignition timing, cold-start enrichment, and cooling fan operation. The Walker Full Service Kit line is focused on OE-style replacement parts for factory systems, and this sensor follows that approach with a direct-fit design.
Key Features
- Part number: 211-91031
- Engine coolant temperature sensor for ECM temperature input
- 2 blade terminals with rectangular female connector
- 12.0 threaded end diameter
- Direct-fit replacement for factory-style installation
- Heat-resistant construction for coolant and engine bay exposure
- Engineered to match OE resistance values, thermal response, and signal output
Fitment and Application Details
Compatible with a wide range of Nissan and INFINITI models, including Fits 2014-2022 INFINITI Q50, N/A; Fits 2019-2022 INFINITI QX50, N/A; Fits 2017-2022 Nissan Armada, N/A; Fits 2009-2022 Nissan Murano, N/A; Fits 1995-2022 Nissan Sentra, N/A; Fits 1995-2021 Nissan Altima, N/A; Fits 2017-2021 Nissan Rogue Sport, N/A; Fits 2017-2021 Nissan TITAN, N/A; Fits 2009-2020 Nissan 370Z, N/A; and Fits 1998-2019 Nissan Frontier, N/A. Additional coverage includes select INFINITI Q60, QX60, QX80, G37, FX35, M37, and Q45 applications, plus Nissan Maxima, Versa, Juke, LEAF, Quest, Xterra, and Pathfinder models.
Walker Products 211-91031 is also listed for select Chevrolet City Express and Mercury Villager applications. For shoppers searching for a Nissan Altima coolant temperature sensor, INFINITI Q50 engine coolant temperature sensor, or Nissan Rogue temperature sensor replacement, this part number provides a direct-reference option for the listed vehicles.
What This Sensor Helps Address
- Check engine light related to coolant temperature signal faults
- Hard starting or rough cold-start operation
- Incorrect fuel mixture from inaccurate temperature input
- Cooling fan behavior tied to faulty temperature readings
- Poor drivability caused by ECM temperature data errors
Installation Notes and Quality
Verify connector style, terminal count, and threaded end diameter before installation. This sensor uses a female rectangular connector with two blade terminals and does not include a wiring harness. On listed applications such as Nissan Pathfinder, Nissan Murano, and INFINITI QX50, confirm the sensor location noted in the fitment data, including thermostat housing, water outlet, radiator, or intake manifold where specified.
Walker Products designs this sensor to align with OE specifications for resistance, thermal response, and signal output so it integrates with factory ECM systems. Part number 211-91031 is built for consistent coolant temperature reporting across the listed Nissan and INFINITI fitments.
