Bank 1 sensor 1 on a '02 Suzuki XL7 should be 5.0 - 6.4 ohms. Looking at the connection with the undo clip pointing down, do an ohms test between the two top prongs. These are the 2 heater wires for the O2 sensor. Depending on manufacturer they will most likely be either 2 white or 2 black wires.
the O2 Sensor Should be on top of your exhaust manifold
Should be the rearmost O2 sensor in bank 2. Use a wrench or O2 sensor socket to get it out. Unplug it first from the harness so it doesn't get all twisted and damage the plug on the car's harness.
The 1993 Chevrolet K 1500 pickup truck 02 sensor is on the back of the air cleaner housing. The O2 sensor should be labeled as such.
Depends on what the problem is or what code was set.
Every 50k miles
The O2 sensor on the 1994 accord dx, lx, or ex is the same, and there are two O2 sensor on the 1994 accord, fornt and the rear. Fornt one is located on the top and it is right on the header and the rear O2 sensor should locate on your cat converter right in the middle of your car. So check which sensor that you need and replace it.
There should be plugs where you unplug your old o2 sensor plug at. If you havent done that then just follow the wire from the plug.
A defective O2 sensor will not prevent the engine from starting. The engine will start and run albeit not as it should.
It appears that all that you can test is the resistance across the sensor. Testing across terminals +b and HT at 20 degrees centigrade (68 degrees Fahrenheit) the front sensor (Bank 1 sensor 1) should give a a reading of 5~7 ohms, the rear sensor (bank 1 sensor 2) should return a reading of 11~16 ohms. Readings outside this range suggest replacing the sensor.
the exhaust, where every o2 sensor is
should be behind the cat converter
The O2 sensor is not a regular maintenance item that needs replacing at a set time or mileage. Replacing a fully functional O2 sensor will not improve performance or mileage. The ECU will set a fault code and alert you to a faulty O2 sensor. They should easily last 100,000 miles.
