Fuse for oxygen sensor


I doubt that there is any fuse for oxy sensor. The system computer is connected directly to the sensors, and no fuse is involved.

I have a problem with the oxygen sensor the check engine light goes on but i changed both oxygen sensors and the check engine light still appears PO135 in 98 acura cl


Check the fuses and replace any blown fuses. This code is for the heater circuit of the O2 sensor. The heater is powered by a fuse which may have blown if the heater or the sensor wiring was somehow grounded.

P0131 sabb 93 2001 po121 error codes


P0131 - O2 Sensor Circuit Low Voltage Bank 1 Sensor 1 (sensor is before the catalytic converter)

Possible causes- Front Heated Oxygen Sensor Bank 1 harness is open or shorted
- Front Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Faulty Front Heated Oxygen Sensor Bank 1
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks
P0132 - O2 Sensor Circuit High Voltage Bank 1 Sensor 1
Possible causes- Front Heated Oxygen Sensor Bank 1 harness is open or shorted
- Front Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Faulty Front Heated Oxygen Sensor Bank 1
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks

I am not really sure what is going on here with the same O2 sensor giving these lean and rich codes, if nothing else is apparent and the engine runs well you may have a defective O2 sensor.

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.

Tech notes The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The Engine Control Module (ECM) monitors how long it take the sensor to warm up and start sending an adequate signal. The code means the the sensor is taking too long to warm up. Replacing the O2 Sensor 1 usually takes care of the problem

Check engine light on- auto zone scanner shows error code p0053 probable cause: 1.-check circuit fuse 2.-relay defective 3.-check circuit wiring Where are fuse and relay located?


The code P0053 is for your Bank 1 Oxygen Sensor, the closest Oxygen Sensor to the engine, connected to the Exhaust. Replace your Oxygen Sensor, clear the code, and see if it comes back.

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.
