Tyco Relay V23076-A3001 for Citroën C2

Translated on 03-10-2026, 1:46.

Good evening.
I have a Citroën C2 here that's having problems with the secondary air pump.
The pump is powered directly by 12V, and I can measure 12V at the supply line. However, the voltage drops to zero as soon as I connect a test light. I suspect that a relay in the fuse box is faulty, but it's difficult to find a replacement.
I have stripped approximately 75% of the wiring harness and have not found any abnormalities.
"The error code P0413 (secondary air pump, circuit malfunction) immediately appears in the diagnostic memory, and while it can be cleared, it reappears immediately. The fuse is, of course, fine."

Do you perhaps have any other suggestions or can you tell me where I can purchase such a relay?

Thank you.

Hi there.

Take a look at the book...

Automotive Relay - Tyco - V23076-A3001-D142 - Citroen C3 - VW Volkswagen T5 / 201460074339

Otherwise, the usual suspects. Mouser, Farnell, etc.

Best regards from Berlin.

...either get a circuit board from Schrotti and take it apart...

or http://www.mouser.de/ProductDetail/TE-Connectivity-PB/1-1393277-7/?qs=IGPQaF7TU6tDbPrrumLsYQ%3D%3D

Hello,
I gave the circuit board to a friend who is an electrician and who has the right soldering skills. He also happened to have a suitable relay.
The vehicle is running again.
Otherwise, he would have also ordered from mouser.de.
The relay for the secondary air pump is located directly above the fuse for that pump.
