P0422 does not refer directly to an O2 sensor. That is a different code. P0422 is about the CAT. How many miles you have it and when did you buy it? VW has extended a warranty on the New Beetles for the CAT to 120,000 mi and 10 yrs. I had the same code and took it to the dealer to see if they'd replace the CAT in the warranty and they did. I had 47,000 miles and bought it at the end of Aug 1999, so I just slipped through. They replaced the downstream O2 sensor as well - all free of charge!

I have a 2008 Hyundai santa fe and I read a p0131 on a scan tool. where is the oxygen sensor bank1 sensor?

code p 0131 refers to heated oxygen (HO2S) sensor 1 bank 1 ---low voltage ===causes --exhaust leak--wiring short to ground ---HO2S sensor ---ECM
the HO2s) is the sensor in the exhaust manifold before the cat converter and bank 1 is closest to the fire wall
the exhaust leak could be in the mesh covered section of the exhaust pipe from the manifold to the cat converter as they crack and that will throw out the HO2s reading back to the ECM

On a Volkswagen Beetle 1999 2.0 is the first cylinder considered upstream or Downstream when replacing the O2 sensor I'm getting a error code reading of P0171 system too lean (Bank 1)

code p 0171 refers to system too lean bank 1=== causes ---intake /exhaust leak---AIR system--MAF/VAF sensor---fuel pressure/pump---injector/s---heated oxygen (HO2S) sensor
the HO2S is the unit that controls the mixture and is located in the exhaust manifold / pipe before the cat converter

the oxygen (O2S) is just like a final trim and reads the cat converter operation and is located after the cat converter

bank one is closest to the fire wall

My 2000 2.0 JETTA is failing inspection and the code pulling up is P0422 but I was told the Cat is in good shape, any suggestions?

code p 0422 refers to main cat converter, bank 1 ---efficiency below thresh hold ===causes cat converter,--- wiring -- heated oxygen sensor (HO2S) 2
heated oxygen sensors are the ones in the exhaust manifolds before the cat converters
they are wired and the wires are delicate and can be easily damaged
O2 sensors (O2s) are found after the cat converters and can determine the quality of the cat performance
At this point I would be looking at the HO2S replacement as that is what the code indicates --IF-- the cat is in proper working condition

Have code P2238 - what could be the cause ?

code p 2238 has 3 references
heated oxygen sensor(HO2S) 1 bank 1,positive current control---circuit low ====causes ---wiring short to ground ---HO2S
second reference
oxygen sensor (O2S) 1 bank 1 positive current---circuit low====causes ---wiring short to ground ---O2S
3rd reference
HO2S 1 bank 1--implausible signal===causes ---wiring---short to positive ---short to ground ---HO2S---ECM
as the heated oxygen sensor is common with wiring problems indicated , maybe changing it will fix the code
HO2S is the sensor in the exhaust manifold in bank1 before the cat converter

2001tiburoncomputor codes, po136 & 141 what do they refer to.

P0136 = Oxygen Sensor Circuit Malfunction (Bank1, Sensor2)
P0141 = Oxygen Sensor Heater Circuit Malfunction (Bank1, Sensor2)


If 4 cylinder engine, there are only two O2 Sensors - Sensor 1 is on top, Sensor 2 is at the bottom

If 6 cylinder, there are four (4) O2 sensors (Bank1, Sensor2 is on the firewall side of this engine and is referred to as the 'DOWNSTREAM' sensor (the one AFTER the Catalytic Converter)

Hi my 1999 1.8T beetle has CEL p0116 and P1196. I've tried fixing my P0116 problem which is temp sensor coolant range per. I've replaced my faulty blue sensor (the square one) with the new green sensor....

P1196=Oxygen Sensor Heater Circuit,Bank1-Sensor1 Electrical Malfunction,
this is the exhaust on the drivers side,and the O2 sensor before the converter.

P0116=ECT, this is the Engine Coolant Temperature switch,NOT the temperature sending unit.

Where is bank 2 for oxygen sensor

if it is a 6 cylinder it is in the front of the motor next to the radiator. bank2 sensor 1. back side of motor next to the fire wall is bank1 sensor 1. the one behind the cat is bank1 sensor 2. make sure that is the problem. if code p0420 is the cat or cat's are bad.
