0413 code

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.

Yes, it is a P code, and on the next time I start it up, then becomes an active code.

Re: 0413 code

Out of pure curiousity, I made the mistake of taking off the EGR valve and succeeded in snapping a bolt off, leaving the rest of it in the manifold. Not fun getting it out.

However, I've since found that running the secondary air pump off the car battery, only works intermittently. There. It appears that it was the secondary air pump after all.

At times the motor does not move and the housing gets hot. I've checked the carbon brushes and they seem fine, and now we enter an area which is beyond my understanding. Is there a thermal cut-out or something inside the motor?

Re: 0413 code

I noticed the armature was dirty looking, so I cleaned that up with sandpaper till it looked like polished copper. Then I saw that one of the windings had come off the armature, so I re-attached it. Now I would love to tell you that it worked perfectly, but it didn't. The same problem remained.

So I bought a brand new generic looking Peugeot secondary air pump for around 40, and fitted it in less than 5 minutes. I cleared the codes with my scanner, and happy days, the ODB light has vanished.

Just a reminder, the EGR valve, as far as I know, has nothing to do with the 0413 code!

To remove the bumper there is one bolt either side of the wheel arch, 4 screws along the bottom, and 8 black button plugs under the bonnet. The bumper comes off with a push aimed towards the front direction of the car. The secondary air pump is situated behind the bumper, on the passenger side.

Good luck!

Re: 0413 code

Well done.

Great skills tracing and fault finding.

You can well imagine how so many vans have been scrapped through daft garage bills.

What age and engine is it..??
