Code p1130 on toyota rav 4 99

SOURCE: Toyota Avalon XLS, yr 2000, engine lights on

P0171 is a lean code. Open the hood, and locate the mass air flow sensor. Small black thingy in the intake tube between the air filter box and the engine, held in with 2 small screws. Remove the connector, remove the screws, and remove the sensor. Look into the sensor, you are going to see a couple of wires deep inside it. They will probabaly be "fuzzy" looking. Spray some brake cleaner on the wires until they are nice & clean. This will cure the P0171 code. Then check the air filter; replace it if it is dirty.

P1130 is an air-fuel sensor code, bank one, sensor one. More often than not, when we see this code, we replace the air-fuel sensor. Buy the replacement from you Toyota dealer, because the aftermarket sensors will not send the proper signal to the ECU, and you will be upset for having to buy a second sensor.

P0440 is a leak in the evaporative side of the fuel system; this looks after the fumes of the fuel in the tank. There are several reasons for seeing a P0440, like leaking vacuum lines, faulty fuel cap, rusty fuel filler tube at the cap, etc. This is kind of difficult to rectify without the proper equipment needed to diagnose what & where the actual leak is.
Hope this helps, please consider kind remarks regarding this solution. Thanks.

I had the same problem. A computer check showed that the emission system was having difficulty. The catalytic converter had to be replaced. The car had under 80,000 miles on it so it was covered by a warranty (State law? Federal law?).
My battery was also dead. That was replaced free too. It had a 7 year warranty.
I do NOT purchase extended warranties.

bank one is the bank closest to the firewall in the manifold but if you replace this one you should do the other or you will get a code for it not long from now because the new sensor will operate much better and faster

Chances are, it's going to be either 1 of the 3 switches that need replacing, a new gas cap or a new charcoal canister. The 2 switches under the hood are the VSV for CCV and VSV for EVAP. The one at the canister itself is the VSV for VSP. This VSV for VSP typically goes bad before the other 2 switches do. Plus, the switches are much cheaper than a new canister. (BTW, VSV stands for vehicle switching valve.)

PO446 is an evap canister code

Testimonial: "Very good- a little too complex for me to fix unless a part can be replaced. Can the repair be simplified?"
