Code p 1130 refers to air/fuel ratio sensor circuit /performance malfunction bank 1 sensor 1
talk with a lexus service shop but I feel that all that is a problem heated oxygen sensor (HO2S) in bank 1 exhaust before the cat converter
that heated oxygen sensor reports the gas composition to the ECM so that the air' fuel ratio can be properly adjusted

That code doesn't mean any sensor is defective, it can be the sensor, problems with the engine or a faulty fuel injector or the wiring or the engine control computer that triggered the fault.

I have check engine code P1354 variable valve timing system bank 2 for my 2000 Lexus RX300. Where is this located?


YES, you have to investigate what is throwing your valve timing off. That could be anything from a vacuum leak to clogged injectors, bad plugs, sensor ect. Have the car analyzed to find the cause. There can be many causes. Good luck

What does code system to lean bank 1 mean on my 2000 lexus rx300


It could be caused by many things, but generally it means that your engine is running too lean - usually indicating a vacuum leak. It could also be that the O2 sensor is bad and giving a false reading.

2000 RX 300. Code P1130. I have already replaced the mass air flow sensor on te top of the air intake. The missing stopped but I still have this code. I have cleared the code twice and it still comes back....


P1130 A/F Sensor Circuit Range/Performance Malfunction (Bank 1 Sensor 1). Some possible trouble areas include: open or short in a/f sensor circuit, a/f sensor, air induction system (which it looks like you already checked), fuel pressure, fuel injectors, or your ECM (Engine control Module). I can send you steps to check these but i need your email address cause i can not post them on the internet do to copy right laws.

Code p1130. where is the sensor located on a 2001 rx300 lexus


P1130 Air/Fuel Ratio Sensor Circuit Range/Performance Malfunction (Bank 1 Sensor 1) 
This sensor is the hardest to get at. It is between the cat and the cylinder block on the bank of cylinders closest to the firewall. Not much wiggle room back there.
Sensor will run you about $225 from Toyota, $275 from Lexus, but you may be able to get a Denso sensor on line.

Good luck and hope this helps. keep me posted.

Check engine light need help


Hi kelly4578, Your Air/Fuel Ratio sensor is failing. It is also called the Bank One sensor. The sensor itself is about $200 from a parts distributor and somewhat more than that at a Lexus parts department. Labor to remove the old sensor and replace it with the new one will also run you several hundred dollars.

If you're mechanically inclined, you can tackle this repair yourself. But you must first determine the exact location of the failed sensor. And be careful not to strip the threads in the manifold when you remove the old sensor.

Let me know if this helps and please rate this solution. lone99star

The first and last code are your start and stop so you can ignore them the P1130 and P1150 are your two front oxygen sensors( pre cats ) bank one and two. Depending on your millage it sounds like it is time for a little maintence. Normally they should be changed at or around 60,000 kms
