Swap pre-cat and post-cat O2 sensors?
Hi All,
Sorry if this question has been asked before, I did a search and couldn't find anything.
I'm driving a 2003 Holden 1.8 Astra sedan I'm 90% sure my pre-cat O2 sensor is cactus. The post cat sensor looks the same (just with a different length of wire leads). I was thinking that swapping them over might be a way of confirming if it is the pre-cat sensor. My understanding is that the post-cat sensors generally don't die that often, so mine is probably ok.
Can anybody see a problem with this? I don't want to cause more problems, but I figured this would be a good way to check before I shell out for a new sensor.
Thanks,
Paul
