Wabco 8130000443 Coolant Temperature Sensor

Description

The Wabco Coolant Temperature Sensor is a critical component of the engine management system, responsible for accurately monitoring the coolant temperature. It is commonly used in commercial vehicles and heavy-duty applications to prevent overheating and ensure optimal engine performance. This sensor provides precise temperature readings to the engine control unit (ECU), enabling it to adjust fuel delivery and ignition timing for enhanced efficiency and reduced emissions. The sensor is 1 x 83 x 147 mm and is manufactured to OE specification. Its robust design and accurate readings contribute to improved engine reliability and longevity.

Key Features & Benefits

This little guy basically measures the temperature of your engine’s coolant. It’s a resistor, so its electrical resistance changes depending on how hot or cold the coolant is. That information, that changing resistance, is sent to your car’s computer – the Engine Control Unit, or ECU. The ECU uses that temperature reading to make a bunch of decisions. It adjusts how much fuel the engine gets, when to turn the radiator fan on, even how the ignition timing works. It's kind of like the brain needing accurate info about body temperature to keep everything running smoothly. A properly functioning sensor is crucial for emissions control too.

Symptoms, Risks & Replacements

If this sensor fails, it can cause all sorts of problems. The ECU gets bad data, so it can’t run the engine efficiently. You might notice things like poor fuel economy, rough idling, the engine overheating, or even the “check engine” light coming on. Sometimes, especially with newer cars, it can prevent the engine from starting at all. A faulty sensor doesn’t always cause a catastrophic failure, but it’ll definitely make your engine work harder and potentially cause other parts to wear out faster. You’ll notice if your fuel economy suddenly drops, or if the engine seems to be struggling, especially on cold mornings.
