Engine Codes

The P0133 is the O2 sensor in the exhaust manifold there is one other O2 sensor by the cat but that sets a different code. Usually the P0133 is set by a bad O2 sensor its a lot cheaper to order one online especially if you get thr universal one that you have to use the old connector from thr old sensor.I got my O2 sensor from www. Rockauto. Com I also have a 5 percent discount code for them if you want it. The P0446 is the evap vent solenoid which is by the fuel filler neck. The P0410 is the air injection system. Do you have a multimeter to do some testing?Also a hand vacuum pump?

Here is a link to the hanp pump iam talking about it allows you to apply a vacuum to parts for testing.http://www.autozone.com/autozone/accessories/OEM-Vacuum-pump-and-gauge-tester-includes-24-in-tube/_/N-25jr?counter=2&itemIdentifier=2080_0_0_
Have you checked all your fuses yet?Make sure you check the 10amp fuse labeled emiss and the the big green 30amp fuse labeled air pump.Lets start there i think they rent that hand vacuum pump at auto zone.We will have to check some of the most common reasons for codes by hand because you dont have a tech2 scan tool etc.The vent solenoid is under the left rear wheel liner its pretty easy to change but untill we check it were not changing it.Let me know what you find.

The fuses I asked you to check in my last posted reply are in the inside fuse box.I also want you to check the 10amp fuse labeled cruise its in the inside fuse box behind the passenger side forward center console panel.

So do you have a multimeter jumper leads with aligator clips and test adpaters to back probe the terminals so you can test and jump the connectors while there plugged in?Also that hand vacuum pump with adapters we talked about?If you do then we can do some testing as much testing as we can without all the special tools.

I just realized that you have a 2002 car and that has a linear combo valve that opens to let air go in the exhaust manifold from the air injection pump. So we cant test that with the hand vaccuum pump like the 1999 and down air injection systems. When you start the car up when its cold can you hear the air injection pump come on?

For the P0133 you can replace the o2 sensor in the exhaust manifold as far as the other codes they have to be diagnosed. Yes the air injection pump is over by your washer bottle. You should be able to hear it on cold start when the car has sat overnight. If you dont hear it then open the hood and have someone start it while your under the hood listening for it. Lets start there and then we will tackle the P0446 code. Keep meposted on what you find.

Heres what you need to do let the car sit overnight while the engine is cold go under the hood go over by the air injection pump. Have someone start the car while you listen for the air injection pump to kick on also at the same time see if your getting power and ground to the pump when the engine starts. Also check the connector to the air pump unplug it and see if the ohms reading at the air pump measures 0.5-19.0 ohms. Also make sure the 30 amp air pump fuse isnt blown in the underhood fuse box is good its one of the big green maxi fuses. Let me know what you find.

1500 ohms?You should be measuring volts not ohms. Measure across the the two wires to the air pump when starting the engine cold if you have battery voltage to the air pump and it does come on and the terminals have a good connection bad air pump.
