Ok I took my car to Autozone and they scanned it and I got two readings:

Reading 1:

Air system bank 2 fault

Explanation - During the air system test the ECM looks for a change in the 02 sensor voltage- No change was detected

Probable Cause:
1 - Air pump electrical circuit fault
2 - Blocked air system
3 - Failed air pump

** What could this be and how do I check or fix this issue?

Reading 2:

Fan control relay 2 and 3 control circuit fault

Explanation - The ECM< has detected a fault on the output driver module for the fan control relays 2 and 3.

Probable cause:
1 - Open or short circuit condition
2 - Failed fan control relay

** Im guessing this is a bad fan control relay in my fuse box in the engine bay?

 

I know the second one is a bad relay... but I just need to know what is an air pump and where is it located? or does it mean I have a bad O2 sensor?

 

Alright nevermind its my air pump check valve I just dont know where it is lol

 

air pump is on the driver side, front side of motor, mine is mounted on the frame, crap i forgot what yr your car is. anyways it has two hoses that come out of it and if u follow the hose from the intake that looks like a heater hose, in size, and it should lead u to it. the other goes to the exhaust manifolds.

 

check valve should be in one of the hoses. i would think the one that goes to the exhaust.

 

Mine is 1996... the black hose that connects to my intake on the back side? that should lead me to it?

 

ill check the parts book. right back.

 

its a round metal valve that hooks to the pipe that comes out of the top of the exhaust on one side and back by the egr on the other. ill see if i can get my camera to work if u like.

 

1) There is no air from the air pump going into the exhaust manifold. When air enter the exhaust system the O2 sensor sees more oxygen in the exhaust. The O2 sensor is good otherwise you would get a O2 sensor code. The probable cause tells you what to look for. Check the fuse and fusible link feeding the air pump relay, check the control wire from the PCM to the air pump relay, check wiring from relay to pump, check pump, check air passages, including check valves, from pump to exhaust manifold (clean them out if clogged or replace if damaged) Can't tell you where the stuff is located because you didn't say what car you are working with.
2) There are one to three fan relays depending on year, engine, and option.

 

sorry, the air intake hose on the front.
