How do I figure out which fuse controls the Oxygen sensors in a 2002 nissan Maxima SE


Good question... there are NO Fuses or Relays which control the Oxygen sensors. A fault code in the ECM access socket will tell you if the oxygen sensors are working properly, if you possess a fault code reader. Most Asian cars, including the smaller Chevy's made in the old Daiwoo factory, use DENSO sensors and most European makes Behr-Hella. If your car is not running right, check the vacuum lines first... there is a schematic inside the hood. Replace your spark plugs and distributor cap/rotor for those cars that use them. Check your plug wires for continuity using a simple multimeter set to resistance... they should all be close! A car of your's age should get the fault code read from time to time... aftermarket code readers are reasonable in cost and the Haynes manual will tell you what they mean in most cases.

I have a 2010 Volkswagen golf trouble code p0037 H02S Heater Control Circut Low Bank 1 Sensor 2. I changed both oxygen sensors and still got the same code. They say it can be the oxygen sensor fuse. I...


Ok vw can be hard to work on so let's make it as easy as possible. You have to fuse boxes and one relay box. Pick up a test light under hood on top of battery fuse box 1 look for power on both sides if so it's good check all fuses next in drivers side door jam fuse box 2 do the same here if you have power on both sides of fuse it's good if you have no power at all it should be good .what we are looking for is one side of fuse to have power and the other side no power it will be blown. Please rate my help

P0037. heater sen. where is it on the engine?


The code is for the heater in the O2 sensor bank one sensor two. That would be the sensor after the catalytic converter on bank one.
It could be the sensor itself or the power supply for the heater.

Subaru wrx impreza showing fault code p0037. how do i fix this fault which sensor is it and where is the sensor located?


http://helpforcars.net/obd_codes/codes.php?code=P0037

It's an O2 sensor according to the above link, and it is bank 1 sensor 2 low, the 2 meaning that it is downstream past the catalytic converter but not on the manifold.

- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse
- Faulty Engine Control Module (ECM) Possible Solution Tech Notes The code means that there is a problem with the heater element circuit of the heated oxygen sensor. Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow, which is a very common problem for this type codes. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors.
Good luck on this repair.
