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.
Ford Engines:You MAFS (Mass Air Folw Sensor) depending on if you car is a z-tec or duratec would be right in front of you if you open the hood (assuming it's a duratec). It is connected to you MAF tube. If you follow your intake it's the tube right before it coonects to your plastic intake manifold. On the MAF tube is a little plug that is your sensor.
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
Smart sensors include environmental sensors (such as temperature and humidity sensors), motion sensors, light sensors, proximity sensors, and biometric sensors (such as fingerprint or facial recognition sensors). Each type of sensor is designed to detect specific physical characteristics or conditions and provide data for various applications.
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 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.
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.
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
Rebuild it. If it's a 97, it must have close to 150k miles.
5 gyroscopic sensors and 2 tilt sensors.
