O2 sensor P0140 error code
Hi, anyone had any experience with P0140 error code on a 2008 impreza sti hatch. The car has been decatted and every 100 miles or so the Eml comes on with code p0140 o2 sensor. Is there a mod you need to do when running a decat etc or is it a fault with the sensor or wiring?
Thanks
Thanks

It's either dead, wiring harness fault, or has been removed in the decat process.

As I posted in your other thread................
you may find a resistor under that gunk, if it's been deleted
