2012 Mercedes-Benz S350 Exhaust Temperature Sensors

EGT sensors frequently seize in the exhaust bung, making replacement difficult and damaging the bung. This Dorman OE FIX solution directly replaces the sensor and comes with a bung repair kit just in case.

Product Features:

• Convenient solution – this replacement EGT sensor comes with a bung repair kit in case the bung is damaged during removal
• Cost-effective fix – bung repair kit allows direct repair of damaged bung instead of replacing entire exhaust pipe
• Complete kit – comes with sensor, new bung, weld-on plate and zip tie
• Quality engineering – designed in the United States and backed by decades of automotive aftermarket experience

Exhaust Temperature

The temperature of various systems must be reported to the engine control module (ECM) as well as other operating system controllers in the vehicle. Coolant temperature, cabin temperature, exhaust temperature and ambient temperature are just a few systems reported by a temperature sensor. The temperature sensor is fed 5 volts by the systems computer, within the sensor housing will be a thermistor, or dropping resistor whose resistance value will change as the temperature surrounding it changes. Changing resistance in the circuit will change the volt signal at the processor indicating the current operating value.

Product Features:

• Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
• 100% thermo-shock and vibration tested to ensure superior performance in extreme conditions.
• 100% end-of-line tested to ensure accurate signal output providing product reliability, every time.
• Tin plated lead frame prevents corrosion and ensures a reliable terminal connection under adverse ambient conditions.
• Lead frame terminal size and location determined using image dimension measuring system or 3D laser scanner.
• Application matched components ensures system operation in like new condition.
