Boas.Estou aqui com um problema com o golf 4 ca de casa,modelo 1.4.
Fiz um scan e o carro apresenta me os seguintes erros:
P0036--H02S Heater Control Circuit (BANK 1 SENSOR 2)
P0141--02 Sensor Heater Circuit (BANK 1 SENSOR 2)
P0138--02 Sensor Circuit Hight Voltage (BANK 1 SENSOR 2)

Alguem me pode ajudar no que estara mal??

P0036 - HO2S Heater Control Circuit Bank 1 Sensor 2

Possible causes
- 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)

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.

HO2S Heater Control Circuit Bank 1 Sensor 2 is the generic definition for the P0036; however your vehicle's manufacturer may have a different definition and information for the P0036 code.


When is the code detected?
The P0036 is set when the ECM detects an open or shorted to ground condition on the heated oxygen sensor heater circuit

P0141 VOLKSWAGEN - HO2S12 Sensor Heater Circuit

Possible causes
- Faulty Rear Heated Oxygen Sensor Bank 1
- Rear Heated Oxygen Sensor Bank 1 harness is open or shorted
- Rear Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks
- Exhaust gas leaks


Tech notes
Replacing the rear O2 Sensor bank 1 usually takes care of the problem.


When is the code detected?
Current amperage in the rear heated oxygen sensor heater circuit is out of the normal range.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Possible higher than usual fuel Consumption


P0138 VOLKSWAGEN - HO2S12 Sensor Circuit High Voltage

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


Tech notes
Replacing the rear O2 Sensor bank 1 usually takes care of the problem.


When is the code detected?
The P0138 code is set when the Engine Control Module (ECM) detects that the rear O2 sensor signal voltage remains excessively high for an extended period of time.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- High Fuel Consumption
- Excessive Smoke from Exhaust
