Because it never fixed it to begin with. Just because the light stayed out for a couple of days does not mean that it ever fixed. The computer has to see the problem occur through several drive cycles consequtively before it sets a code and turns on the light. This can take several days. My guess is that you have something else wrong with the EGR system that is causing the computer to see little or no activity at the DPFE sensor whenever it commands the EGR on. And it is probably NOT the EGR valve. Ford EGR valves seldom fail. There is one other possibility that you installed the DPFE backward. I would pull it off, and make sure the small diameter neck on the sensor is one the small diamter hose and the big diameter neck is on the big diameter hose. Otherwise, you probably have something causing little or no flow in the EGR system such as an EGR control malfunction, or a stopped up EGR passage in the intake manifold area.
there are 4 o2 sensors on the gen.3 sables, one off each manifold, and one before each cat.
it all depends whats wrong with it, it may be the brain of the system or it could just6 be your wheel speed sensors throwing it off
The different types of smart sensors include pressure sensors, electrical conductivity sensors, dissolved oxygen sensors, turbidity sensors, pH sensors, temperature sensors and ORP sensors.
There are many types of sensors in cars. Some include parking sensors, blind spot monitors, water sensors, and tire pressure sensors, temp sensors, oil pressure sensors, Oxygen sensors, .
The sensors that an engineer puts on a robot are entirely dependent upon the functions that the engineer perceives that the the robot will be called upon to perform. Some, but not all, of the sensors may be: proximity sensors, pressure sensors, light sensors, magnetic sensors, a camera, temperature sensors, accelerometer, speed sensor... The question isn't, "what sensors does a robot have", but rather, "what sensors does the engineer think that the robot should have?"
melvsta here, how longs the page, loads, speed sensors, air pressure sensors, o2 sensor, parking sensors, wheel sensors, etc
sensors for mechanics
It is located on the drivers side crankcase, just below the upper intake manifold. You will need to remove the air filter assembly, the throttle cables, and you might need to move the other bar that is connected with maybe 5 sensors, to be able to get to it.
5 gyroscopic sensors and 2 tilt sensors.
The back up / reverse sensors are the round things molded into the back bumper cover - about 1" in diameter.Note: The Owners Manual refers to this as the "Parking Assist" system. That's why there's a button to the lower left of the radio with a large P on it - which allow you to temporarily disable the warning system.
What sensors??? Tire pressure sensors? You can reset the tire pressure sensors through the instrument cluster
There are sensors all over the engine and transmission. There are also sensors at the wheel bearings and in the exhaust.There are sensors all over the engine and transmission. There are also sensors at the wheel bearings and in the exhaust.
They don't have sensors.
If your 2000 Ford Expedition is throwing a code 1132, then you should first try to change the oxygen sensors. If that does not remove the code, a mechanic will need to determine the exact cause.
Respiratory sensors. Respiratory sensors monitor oxygen intake and carbon dioxide output.
Gyro Sensors are devices that show rotational speed in degrees per second.
Insect sensors are called Antennae.
He has groud and visual sensors
light sensors are used in cars, televisions and computers. there are different types of light sensors.
What type of sensors are you talking about? There are many sensors, and many different types.
All of what sensors? There are dozens of different sensors in cars: O2 sensors, oil pressure/temperature, coolant temperature, fuel pressure, and so forth. All are different, and each car typically uses sensors that are different from sensors in other cars.
Which sensors....theres a lot of them
what specific sensors?
