2011 987.2 O2 bank 1 sensor location
Hi all -
My 2011 Cayman is displaying a P2231 code, O2 sensor short circuit to heater bank 1 upstream. I've got the car up in the air but am unsure which O2 sensor is bank 1 upstream? Been searching online for a diagram but no luck so far. Is this on the driver's side? Was planning to take this car to Shenandoah Nat'l Park ride this weekend and hoping to get this swapped out. Thanks for your help! Paul |
