Product Line Details

NTK Engine Coolant Temperature Sensor products are part of NTK’s technical sensor lineup, backed by NGK’s automotive experience. NTK applies OE application data and testing methods such as thermal shock, vibration, and OBD verification to help ensure the sensor meets or exceeds OE specifications. This makes EF0069 a practical replacement choice for vehicles that rely on accurate coolant temperature input for fuel control, idle quality, and cooling fan operation.

Compatible With select Honda Accord, Civic, CR-V, Odyssey, Prelude, Pilot, S2000, Civic del Sol, and Insight models, plus Acura Integra, TL, CL, RL, MDX, NSX, Legend, and EL applications, as well as the Isuzu Oasis. Fits 2000-2002 Honda Accord, lower; fits 1998-2002 Honda Accord, lower; fits 2001 Honda CR-V, right; fits 2003-2004 Honda Pilot, without leads; and fits 1996-2004 Acura RL. This part cross-references Standard Ignition TX37 and Beck/Arnley 158-0154 for the same application. Part number EF0069 is also listed for multiple Honda and Acura OE references.

Common Issues This Sensor May Address

• Incorrect coolant temperature readings at the engine control unit
• Hard starting or rough cold operation caused by inaccurate temperature input
• Cooling fan behavior that does not match engine temperature
• Fuel mixture or idle concerns tied to faulty coolant sensor data
• Check engine light concerns related to coolant temperature sensor performance

Installation Notes and Tips

Verify connector style, terminal count, and sensor location before installation. EF0069 uses a blade terminal, round connector, and female connector housing, and it does not include a wiring harness. Fitment locations vary by vehicle, including intake manifold, water outlet, water pump, cylinder head, thermostat housing, block, and water crossover. Confirm the exact engine-side location on the vehicle before replacing the sensor.

Quality Assurance

NTK manufactures technical sensors using OE-based application data and validation testing. Each sensor is subjected to demanding checks, including thermal shock, vibration, and OBD verification, to support consistent performance in service.
