Hi

There is some news from France.

Just intalled my HF Cats (INVIDIA) see photo



After few kilometers I have these codes
P0139 - O2 Sensor Circuit Slow Response Bank 1 Sensor 2
P0159 - O2 Sensor Circuit Slow Response Bank 2 Sensor 2
P0137 - O2 Sensor Circuit Low Voltage Bank 1 Sensor 2
P0157 - O2 Sensor Circuit Low Voltage Bank 2 Sensor 2

Can someone give me a good advice and what to do ?

Thanks
Phil

For P0137 & P0139 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 may be faulty
- Exhaust gas leaks

Oxygen Sensor Bank 1 replacement normally solve this issue.

Thank you Bboyz

Could you tell me where are these sensor ?

is it those who are connected directly to the HFC ?

What about the price ?

Phil,

Yes those sensor are the sensors connected to HFC. About the price, not sure it varies.

Check that there is no Exhaust leak, since the HFC was replaced.
To test if the sensors are faulty, put back the old Cat, reset the code and test drive for kilometer. This will tell you if the issue is the sensor.

If everything was good prior to the HFC install, you may just need some Oxygen Sensor Spacers.

First of all --> HAPPY NEW YEAR !!!!!!


Ok Good idea but a lot of work ... The guy who installed it didn't put any Exhaust Gasket between exhaust manifold and the HF Cats... may be this is the pb ?

I hope not but see above ...

I'st strange because before programming ECU I had no pb with the HFC ...

All the best
Phil
