Where is the EGR temperature sensor located on a car?
The EGR temperature sensor is an engine management sensor that is part of the EGR system. It works together with the EGR solenoid to control the flow of the EGR system. The sensor is installed in between the exhaust and intake manifold, and monitors the temperature of the exhaust gases. When the temperature rises,…
What are the signs of a bad EGR sensor?
Common signs include engine ping or knock, the Check Engine Light coming on, and failing an emissions test. 1. Engine ping or knock 2. Check Engine Light comes on 3. Failed emissions test Average rating from 129,472 customers who received a Exhaust and Emission System Inspection.
Where are the back O2 sensors located on a car?
Back O2 sensors are located after the catalytic converter, a part that facilitates the conversion of pollutants in the exhaust to harmless by-products. These sensors monitor the efficiency of the converter.
How does the EGR pressure feedback sensor work?
When the EGR pressure feedback sensor detects that the pressure is low, it will open up the EGR valve to increase flow, and just the opposite will close the valve if it detects that pressure is too high.
What happens if your EGR sensor is bad?
If the EGR pressure sensor sends any false reading to the computer it can cause the EGR system to malfunction. A malfunctioning EGR system can lead to engine performance issues such as rough idle, engine hesitation, and a decrease in overall power and fuel efficiency. 2. Failed emissions test
Where is the O2 sensor in the engine?
The engine computer is responsible for calculating how much fuel the engine needs based on the amount of oxygen in the system, and it relies on a good O2 sensor to function properly. The sensor is mounted in the exhaust manifold to monitor the amount of oxygen in the exhaust.
When the EGR pressure feedback sensor detects that the pressure is low, it will open up the EGR valve to increase flow, and just the opposite will close the valve if it detects that pressure is too high.
What are the symptoms of a bad O2 sensor?
Bad O2 sensor symptoms include poor gas mileage, rough engine idle, starting trouble, and even failure of the catalytic converter. Often, the check engine light will come on to provide ODII trouble codes to check with a code reader.
What happens to the EGR when the temperature rises?
When the temperature rises, the EGR temperature sensor will send a signal to the computer that will increase the flow in order to reduce pressure and temperature of the system.
