Bosch Engine Coolant Temperature Sensor 0280130129 — OE Fit for Nissan/Infiniti, Wide Temp Range, Vibration‑Resistant

This Bosch coolant temperature sensor is built to the manufacturer’s standards for precision and durability so your engine control system receives reliable temperature readings. Designed for a wide operating range and high vibration resistance, it helps the engine manage fueling, ignition timing, and cooling-system responses. It’s a direct-fit option for many Nissan and Infiniti models, delivering the fit, function, and performance expected from an OE supplier.

How does this sensor keep my engine running correctly?

The sensor provides real-time coolant temperature readings to the engine control unit (ECU), which uses that data to adjust fuel delivery, ignition timing, and cooling fan activation. Accurate temperature input helps the ECU maintain efficient combustion and prevent overheating. Bosch’s testing and design reduce erroneous signals that could trigger incorrect engine adjustments.

• Measures coolant temperature within a wide -40°F to +260°F range.
• Stable electrical output for reliable ECU interpretation.
• Engineered to resist vibration and thermal cycling for consistent readings.

Will this Bosch sensor fit my vehicle and how do I verify fitment?

The BOSCH 0280130129 is compatible with many Nissan and Infiniti applications, but fitment can vary by engine and model year. Always check the vehicle-specific fitment tool or consult the parts catalog to confirm compatibility. If your vehicle is listed among supported models, this sensor is a direct-replacement option that matches OE specifications.

• Compatible with select Nissan models like Altima, Frontier, Rogue, and NV-series vans.
• Fits select Infiniti models including QX50 and QX56—verify engine variations.
• Use the online fitment checker or VIN lookup for exact confirmation.

What are the construction features that improve reliability?

Bosch designs this sensor to withstand tough under-hood conditions: thermal extremes, mechanical shock, and exposure to coolant. The sensor’s robust housing and sealed connector help prevent corrosion and signal degradation. These durability choices aim to reduce failure rates and extend service life compared with lower-quality aftermarket parts.

• Sealed connector design to resist moisture and contaminants.
• High vibration tolerance to minimize mechanical wear.
• Wide operating temperature range to handle cold starts and high-heat operation.

How do I spot a failing coolant temperature sensor and what then?

Common signs include erratic temperature readings, the check engine light, poor fuel economy, or cooling fan running incorrectly. If you observe these symptoms, confirm fault codes with an OBD-II scanner and inspect the sensor and wiring. Replacing a worn or failed sensor with a Bosch OE-grade unit restores correct temperature feedback to the ECU.

• Look for fluctuating gauge readings or persistent engine warning lights.
• Confirm diagnosis with trouble codes P0115–P0119 family or related codes.
• Replace the sensor, inspect wiring, and clear codes after installation.

Who is this for: Drivers and professional technicians seeking a reliable, OEM-quality coolant temperature sensor for compatible Nissan and Infiniti vehicles. This Bosch part is aimed at those who prioritize accurate engine temperature data, durable construction, and a direct-fit replacement to maintain engine performance and system efficiency.
