AFI CTS1013
2-Pin Threaded Sensor
350Z & 370Z
Description
AFI CTS1013 is a replacement engine coolant temperature sensor for the listed Nissan 350Z and 370Z applications. Choose it when testing confirms an inaccurate or intermittent coolant-temperature signal to the engine control unit.
The sensor reports coolant temperature to the ECU for engine-management and cooling-fan operation. It does not regulate coolant flow and should not be confused with the separate thermostat.

Why Choose AFI?
- AFI specialises in replacement fuel-injection and engine-management components for Australian vehicle applications.
- CTS1013 is catalogued across the listed 350Z engine variants and matches the temperature-sensor references used by the 370Z.
- The dedicated part number, two-pin connection and threaded installation provide clear identification before ordering.
Common Inspection Reasons
- Implausible or intermittent coolant-temperature readings
- Cooling fans operating unexpectedly
- Difficult cold starting, unstable idle or unusually rich operation
- Coolant-temperature circuit codes such as P0115–P0119
A coolant-temperature-related fault code does not confirm sensor failure by itself, as coolant level, wiring, connector, thermostat and actual overheating faults can produce similar symptoms.

Check Before Ordering
Confirm your model, year and engine, then compare the two-pin connector and fitted sensor with CTS1013 or Nissan reference 22630-44B20 / 22630-ED000. Allow the engine and cooling system to cool completely before any removal or installation work.
