Frequently Asked Questions (FAQs)
1. What is an exhaust gas sensor?
What is an exhaust gas temperature sensor? As its name suggests, the exhaust gas temperature sensor measures the temperature of the exhaust gas. This information is then relayed back to the engine control unit or ECU, where appropriate action is taken.
2. What sensors are on the exhaust?
Oxygen sensors (O2) are typically installed in the exhaust manifold. They monitor oxygen because this is the atmospheric gas that mixes with your fuel to generate combustion.
3. What does the exhaust gas pressure sensor do?
The Exhaust Gas Pressure Sensor is a Differential Sensor measuring the pressure difference between gas in the intake and the outtake of the Particulate Filter. The outtake may be directly set to ambient pressure depending on the model.
4. Where is the exhaust gas temperature sensor located?
The EGR temperature sensor is usually mounted in the exhaust manifold or mounted near the EGR valve.
