P2031 - EXHAUST GAS TEMPERATURE SENSOR CIRCUIT BANK 1 SENSOR 2
| Description: | The PCM monitors the operation of the exhaust gas temperature bank 1, sensor 2 (EGT12) to determine if the EGT12 sensor responds to the increase in temperature of the exhaust gas, during vehicle operation. The PCM then compares the measured temperature to a modeled value. This DTC sets when, after 5 minutes of driving, following a 6 hour soak, the EGT12 sensor temperature does not correlate to the modeled temperature of 150°C (302° F). | ||
| Possible Causes: |
