P0135 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1) Bank one is drivers side. Sensor 1 is the one closest to the engine.
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.

hai my car is ford fiesta zetec 2003 5door ,in my cay o2 sensor have fault .can you tell me how many o2 sensor are there and were is location
Yep, itll just be harder on fuel, may not run as good a usual and a bit harder on your cat. converter, not a big deal but you should get it replaced, itll save you money in the long run to just get it done.
bad O2 sensor
You can find O2 sensor wiring diagram for a 2003 Tiburon GT in the owner's manual. You can also find it at auto parts stores.
The O2 sensor on a 2003 Cadillac Northstar engine is located in the exhaust manifold. The readings from this sensor are sent to the vehicle's computer, which makes constant adjustments to the fuel and air mixture.
its the O2 sensor on the driver side above the catalytic bank1 sensor 1 is the passenger side above the catalytic bank2 sensor 2 is O2 below catalytic on driver side bank1 sensor 2 is O2 below catalytic on Passenger side
if you disconnect the o2 sensor cable in the air intake then start the engine you would see the check engine sign turned on in the gauge panel. It is on then the sensor is working if off the the sensor may have problems
Bank 1 is cylinder 1 side of the motor. Sensor 2 is the back oxygen sensor (after the catalytic converter.
