I need a Mass air flow sensor, rear oxygen sensor, and the oil control valve for the 2,4,6 cylinders...

These are the numbers i have.

22204-07010- Mass Air Flow Sensor.
15330-0A010 Pass side Oil Control Valve
89465-49075 Rear Oxygen Sensor


That all good??

should add the code is a P0172 rich system code, with the multiple misfires on P0300,p0302,p0304,p0306.

Just plug in your vehicle and year on this site and you will find the lexus part numbers...

maybe im just slow... but when i tried to use the search function it wouldnt work...and i couldnt find the sensors in either the electrical, or exhaust section...... i actually did try that site from the last thread, but couldnt find what i was looking for, maybe im just not looking in right place.

Leines

i found the mass air flow..and it has a different part then above... but when i look on ebay..they list both these numbers in the listing..

22204-21010 and 22204-07010

iim pretty sure one is just the new number in that case.

If you can order parts from Amazon in Canada, you can get the oxy. sensor a lot cheaper than from a Toyota or Lexus dealer. Don't know if that's the Oxy. sensor that you're referencing or the A/F ratio sensor, since the # isn't familiar. The A/F ratio sensor is less than $100. at Amazon. I'm sure they sell the Oxy. sensor also (the one BEHIND the Cat. Conv., under the drivers seat), but since you're in Canada, all bets are off on you using the same sensors as we do here. The A/F ratio sensor in an OEM Denso on Amazon is part # 234-9009. You might do well to try and read they part # from the sensor. It is laser etched into the barrel of the sensors.

oh ****.. i was under the impression oxygen sensor and A/f sensor was the same thing??? the guy at the toyota dealer said rear oxygen sensor was a P0172 code....

Try lexuspartseast.com they have the diagrams up as well. Just punch in your vin and you can search. You will have a part # and picture from the service manual.

No, not even close. The codes on the A/F ratio sensors (in the front, on the exhaust where it comes out of the manifold, one on Bank 1 and one on Bank 2) The codes that are possible on those sensors are P1130, P1133 & P1135. On bank 2 the possible codes are P1150, P1153 & P1155. I don't think he's right about that P0172 because that's for Bank 1 and the Oxygen sensor would only tell whether the Cat. is working properly, I don't see how it could determine bank.

Leines

so which sensor does the P0172 point too... when reading this forum there was a thread that said A/F sensor was a possible cause....

Ordering the parts today.. any help greatly appreciated before i order something i cant return.

Cheers

Leines

going back and reading what you said... when i scan p0172 is just says system rich.. it doesnt say a bank... im surprised that when i search this site for p0172 it doesnt come back with nearly the amount of threads as some other codes...

code58

http://www.obd-codes.com/p0172 As you can see from this OBD codes site (one I use frequently and feel is a very helpful site) it refers to P0172 as system rich, Bank 1. An A/F ratio sensor can detect banks because it has one on each bank, but an Ozy. sensor can't because there is only one and it's behind the Cat. Conv. to determine if the Cat. is doing it's job properly.

F my life.... it looks like the 2//4/6 is the drivers side not the pass side and i just ordered the wrong part and waited two weeks to get it here.... FF FFFFFFF i am so pissed off right now, cause im in canada and ive been almost three weeks now waiting for parts to arrive.... FFFFFF

code58

I have re-read the posts and am not even sure WHAT part you ordered, since you didn't say. If it's on the engine, there is no "drivers side" and "passengers side". There is "Bank 1" and "Bank 2". Bank 1 is to the rear, by the firewall and Bank 2 is to the front, by the radiator. 2/4/6 would be to the front, by the radiator.
If you're talking about the OXYGEN sensor, you would have to have dual exhaust to have a "drivers side" and "passengers side". I believe most RX 300's only have a single exhaust.
