Remove pump and bracket as an assembly.ġ. loosen the sway bar bracket to remove the pump bracket.Ĥ. Push locking tab on electrical connector to unlock and remove connector.ģ. I need the code that you saw to hep narrow the reason for failure.Ģ. The code number does not mean to replace the pump, it means it either has a voltage issue or a leak in the system. It has an electrical connection and 2 hoses. The leak detection pump is the part you posted. That's why repairing one doesn't solve the problem, and the second leak gets detected and the Check Engine light turns on again. It allows us to inject a white, non-toxic smoke into the system, then we search for where it is sneaking out. That's where the smoke machine is needed. Even when we find suspect parts visually, we would never send you on your way without proving or verifying that was the cause. While a valve could be leaking, it is much more common to find a rusted hose clamp or a dry-rotted and split rubber hose. If the fault code refers to a 'small leak detected', those can be almost impossible to find without the use of a smoke machine. There are a lot of other things we have to rule out first before spending your money on a part. When a sensor or other part is referenced in a fault code, it is actually the cause of that code about half of the time. They only indicate the circuit or system that needs further diagnosis, or the unacceptable operating condition. Diagnostic fault codes never say to replace a part or that one is bad. The people at many auto parts stores will read them for you for free, but keep in mind they're in the business of selling parts. If that method doesn't work, you'll need a fault code reader to see the codes. This is the list I look at to see the definitions: Cycle the ignition switch from 'off' to 'run' three times within five seconds without cranking the engine, leave it in 'run', then watch the code numbers appear in the odometer display. You should still be able to read those yourself on a 2005 model. The first step in the diagnosis is we need to know the exact diagnostic fault code number. That pump is just one part of a complete evaporative emissions system.
