Guys,

I know this code its everywhere, I had it not so long ago, replace the 02 sensor (the one in front of the radiator, with a Denso 02 sensor) and now the CEL is back again. Went to Autozone, they scan the computer, and walla!!!

The guy said that it could be also the A/F meter, or some kind of a vacuum leak. I did remove the PCV valve from the intake and plug it (well sealed)

Anyone has an idea?

Thanks

P1130 is Bank 1 Sensor 1, that's the one behind the engine.

You know we have similar setups with the PCV valve. I hope you mean that you plugged up the hole on the intake manifold and not the hole where the PCV valve goes itself, because if not, that will cause an issue on the rear bank and can affect Air/Fuel issues back there.

Were they able to check readings on the A/F sensor, as some scanners can check freeframe readings to see what the readings were on both banks?

Lex,

Yes, the intake is plugged, the PCV valve is open. Is that sensor the same part # as the one in the front, close to the radiator? Do you have the part #?

Unfortunately, they have a cheap scanner.

Thanks

Yes, it's the same exact sensor.

The two Toyota part numbers I have are 89467-48011 and 89467-48010.

but the Denso number is 234-9009.

The 48011 would be the current number. The 48010 was the original number they were built with.

One other thing I should mention, because I know you have the same setup on the PCV valve and crankshaft valve, with the PCV valve, I hollowed mine out (it's the plastic kind) when I originally did the first modification back in 2008. That seems to let the engine run a bit smoother than when it has that spring in it.
