Product Information

Full details

The Valeo Exhaust Gas Temperature Sensor (MPN 368862) is designed for automotive technicians and DIY enthusiasts who require precision-engineered engine management components that meet strict original equipment (OE) specifications. This sensor is crucial for maintaining optimal vehicle efficiency and accurate thermal monitoring within the exhaust system; however, users should verify compatibility with their specific engine make and model before installation, as incorrect fitment can lead to erroneous data readings.

Extended Product Information

FAQs

What is the primary function of this sensor?

It monitors exhaust gas temperature to help the ECU adjust engine performance, protect exhaust components from overheating, and optimize fuel efficiency.

Does this sensor work with all vehicle makes?

No, it is designed for vehicles that specifically require a 2-pin, M12x1.25 threaded EGT sensor. Always check your vehicle's service manual or cross-reference your part number.

Can I use an impact wrench to install this sensor?

No, it is highly recommended to install the sensor by hand and use a torque wrench to prevent damaging the threads or the delicate internal sensor components.

What does NTC mean?

NTC stands for Negative Temperature Coefficient, meaning the sensor's electrical resistance decreases as the temperature of the exhaust gas increases.

Should I apply grease to the sensor tip?

Absolutely not. The sensor tip must remain clean and free of oils or grease to measure temperature accurately.

Troubleshooting

Check Engine Light remains on after installation

Clear the diagnostic trouble codes (DTC) using an OBD-II scanner, as the ECU may need a manual reset to recognize the new sensor.

Erratic temperature readings on dashboard or diagnostic tool

Inspect the 2-pin connector for corrosion or loose pins and ensure the electrical harness is not resting against hot exhaust components.

Pros and Cons

Pros

  • Meets strict OE quality standards
  • Precise NTC sensor technology
  • Easy installation due to exact dimensions
  • Resilient to high exhaust temperatures

Cons

  • Requires specific thread compatibility (M12x1.25)
  • Limited to vehicles with 2-pin connector systems
  • Professional installation recommended for proper torqueing

Setup, Compatibility & Care

Before installing, ensure the engine is completely cool to avoid thermal burns and thread damage. To install: 1. Disconnect the negative battery terminal. 2. Carefully unscrew the existing sensor from the exhaust manifold or pipe. 3. Apply a small amount of anti-seize compound to the threads of the new Valeo sensor if necessary, ensuring no material touches the sensor tip. 4. Thread the M12x1.25 sensor by hand to prevent cross-threading, then tighten to the manufacturer's specified torque. 5. Connect the 2-pin plug until it clicks into place. For care, avoid using harsh chemical cleaners on the sensor probe, as this can degrade the NTC element's accuracy over time.
