Hi

I have a problem with above codes and I have no idea how to fix it.

It started from the code suggested that Oxygen Sensor Bank 2 Sensor 1 is broken, so I replaced it with new Denso DX0109 (my frien has LS430 and he used the same model and it is working fine).

Then, P0150, so ok...I bought another one Denso DX0109 and replaced Oxygen Sensor Bank 2 Sensor 2.
After about 10 km, Check Engine disappeared, but after about 50 km I got:

P0130, P0133, P0150, P0153 codes

I cleared the CE light, but after 50 km, CE back.

The next problem is that I feel smelt from the exhaust.

Any idea?

Thanks

You have a leak in your exhaust system. Maybe a gasket that is dad (broken) and this causes the leak. Also maybe, one of your exhaust pipe have a hollow or is cracked and so you smell what you smell.

Go to any muffler shop let the guy what you smell and he can let you know if you have a crake on you system or you need a new gasket. 99% of the time is, that you need to install a new exhaust gasket.
Them clean the cel and see what happen. Good luck.

Hi

I checked exhaust system 3 times, and there is no leak.

Do you know where can I find information about Oxygen Sensors voltage? I have Techstream so I can check how all Oxygen Sensors are working.

Thanks.

Thanks Mcom

Today I disconnected battery for about 2 hours, I will wait for next CE light and check codes.

But I'm thinking, maybe just new O2 sensor is not as fast as should be, so I will try to replace it once again.

Hi

Thank you for all suggestions, but:

I replaced all Oxygen Sensors with the same, original Denso replacement: Denso DOX-0109 (this is normal O2 Sensor but without the connector). Link to DOX-0109 Description: http://denso.elcome.co.uk/ecat/Search/DOX-0109?root=http://www.denso-am.pl/&lang=pl

Now I do not have problems with rear Sensors, but only front. So now I have

P0130 - Oxygen Sensor Circuit Bank 1 Sensor 1
P0150 - Oxygen Sensor Circuit Bank 2 Sensor 1

I double checked few sites, which Sensor should I have and I found 2 versions:

1st:
rear: 89465-30630
front LH: 89465-50120
front Rh: 89465-50130

2nd:
B1S1=89465-30430
B1S2=89465-30440
B2S1=89465-30470
B2S2=89465-30450

and my DOX-0109 is ok for both versions :|

The problem is with first sensors, so I think I can ignore catalyst problem etc

Is any possibility that the problem is not with the O2 sensor but something with fuel / injectors?

one more: previously I had CheckEngine light after about 40-50 km, now after 200-300 km.

Thanks

Hi

Just letting you know that the problem is solved.
I found that few cables near ECU were in bad condition, I used insulation tape and now it is ok.
Thanks
