Can 02 sensor CEL cause immobiliser/ignition faults?
Hi all,
Recently, my car has thrown my a CEL (P0031) 02 sensor issue.
However, at the same time - it's having immobiliser issues, like it'll let me in and turn ignition on and prime the fuel pump, but it's intermittent in letting me actually start. Sometimes it'll take a couple of attempts, but yesterday it stranded my at the hospital for 35 minutes until it let me start.... which isn't ideal haha.
I'm taking a guess in that one problem has caused the second? Car electronics really are not my strong point though!
Cheers.
