Oxygen Sensor Relay
Hi
I noticed during the weekend that my 91 C4's Oxygen sensor Relay is missing (Think it's R41). Is this normal or has the previous owner removed it for some reason? .
Thanks in advance.

Hi Adrian,
Sorry, you're right, it's a Check Cat Converter Relay (I guessed R41 but it's in the 40's). I think it checks for the operation of the converter? Perhaps a US emissions thing?
