Hello. I love my Ulysses, and it's probably not her fault, but I'm absolutely stumped on a job I'm working on. Hope you all don't mind me wracking your brains having only just joined, but I am quite frankly desperate, and after having trawled the web for the past 24 hours without finding the solution, I realise that I need help. Who knows, the answer might provide some comfort to some other lost soul in the near future.
I have a 0413 code, indicative of a problem on the secondary air system. Secondary Air Injector Switching Valve A Circuit Open. I disconnected the pump and wired it to battery to learn that it does indeed work, so I am to believe that the car is refusing to send a voltage to the pump for some reason.
Does any one know where the relay is situated? Can anyone confirm that it is an integral relay situated in the centre of engine fusebox? I found one cable which appears to co-ordinate with the pump feed in terminal 16. After pulling this relay, and running a lead between them, would anyone know why I cannot find continuity between terminal 16 and the pump feed?
When the relay is connected, would anyone know why the voltage on terminal 16 remains weak on start-up?
I also cannot make sense of the changeover valve. Other models of car appear to have an entry for a hose from the vacuum system, which can allow tests with a vacuum pump. As far as I can tell, there are no signs of one on the changeover valve, nor on the solenoid valve. How then are these valves operated if not by vacuum?
Any ideas, any at all, will be much appreciated.
