P0544 - EXHAUST GAS TEMPERATURE SENSOR CIRCUIT (BANK 1 SENSOR 1)
| Description: | The PCM monitors the operation of the exhaust gas temperature bank 1, sensor 1 (EGT11) to determine if the EGT11 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 EGT11 sensor temperature does not correlate to the modeled temperature of 170°C (338° F). | ||
