Q: What does code P1186 mean?

EOT Circuit Performance. P1186 on Chrysler vehicles means the powertrain control module (PCM) has detected that the engine oil temperature (EOT) sensor circuit is not performing as expected, typically because the reported temperature is out of range or inconsistent with other temperature inputs. The PCM compares the EOT signal against a model of expected oil temperature and flags the code when the circuit's behavior falls outside the calibrated window.
