Bought a 2003 6 speed Convertible several months ago with just 2000 miles on her. Ran fine for 500 miles and then got check engine light. Using the great threads on this Forum, I figured out how to pull and clear the codes --- but I keep getting back the check engine light and the code P1415. So yesterday, I pulled off the exhaust check valve onthe drivers side to test and inspect. It looks fine and you can easily blow air through it in one direction and it won't let you blow air through it in the other direction and the valve looks new in the inside --- so with so little milage on the car that valve is fine. Then, before I reconnected the valve, I started up the car to see what type of air flow was coming from the pump. When I put my hand in front of the rubber hose that connects to the exhaust check valve, there was a SLIGHT breeze --- but slight --- I was expecting something you would get from a hair dryer. But, I'm not getting a P1416 code which means the other side of the engine seems to be getting enough air. I'm lost --- any ideas before I drag the car to the dealership?

Thanks

 

It's very unusual to get only the (bank 1) P1415 code. If you're not getting the (bank 2) P1416 code as well,I would have to say that you do have sufficient air output from the A.I.R. pump.

Bank 2 is the right side,and is farther away from the pump.Usually,as it did on my car,the P1416 code will be the first to show up in the secondary air system.

When you had the check valve removed for inspection,were you able to easily blow air through the downstream piping to the engine?

 

Yes, I could blow air easily through the check valve. Tomorrow, I'm going to pull the hose directly off the pump to see what kind of air flow I'm getting directly from the pump. If the airflow is strong, then there is some kind of obstruction in the air line going to the bank 1 check Valve. Also, Iwill check the vacuum hose that runs from the vacuum canister to the valve directly on the air pump to see if there is a kink or leak in this vacuum hose. Very strange --- but I suppose it could be a falulty O2 sensor as well ----but the fact that the air flow was so weak at the bank 1 check valve leads me to believe it's a problem with the airflow from the pump to the check valve.

Also, where is the fuse for the air pump? Maybe I should replace that to play safe

 

Power is supplied to the pump, pump relay, and pump solenoid valve by fuse #50, which is located in the underhood fuse block near the battery.
