Secondary air pump failure

Featured Replies

OK so my secondary air pump, the one that runs for a couple of minutes on a cold start (apologies if I got the name wrong) has died and as such my car now has the CEL on.

The thing has cost a fortune in repairs over the last 6 months and seeing as this doesn't effect the running of it beyond the first couple of minutes I'm not in a great rush to fix it.

In the mean time is there a way to stop the CEL coming on? I can clear the code but it pops up again sooner or later :p

Thanks :)

why not just remove the pump?

Would that stop the CEL from coming on? If it does then I would assume that I can leave it in place but simply unplug it?

Removing the pump will not remove the CEL. If anything, and depending on what else you remove with it, it will give you more codes.

In terms of the resistor,it will depend on the code you've got, but it is an easy and cheap thing to do with a number of guides showing you how, both on this forum and others. RonClubley's link above is a very good for the removal of the pump altogether.

I'd suggest trying the resistor route first, although given you don't seem to want the pump, it would make sense to remove it and the associated hoses, etc, but this takes a little more planning and the purchase of a blanking plate if you take the combi valve off.

I've got a working pump in the garage if you want to make me an offer.

Replace it with a resistor - that stops the CEL I think.

Mine's on the shelf in the garage :)

Brilliant, thanks for the info. Very useful :thumbup:

Thanks for the offer but to be honest since getting the Piper exhaust cold starts have been embarrassing! At least without the pump blasting more air in there it sounds slightly better!
