P0A02 - MOTOR ELECTRONICS COOLANT TEMPERATURE (MECT) SENSOR CIRCUIT LOW
| Description: | A short to ground or signal return on the MECT circuit produces a low voltage (approximately 0 volt) to the powertrain control module (PCM). A minimum of 100 mV difference exists between the short circuit voltage and a valid sensor reading at 150°C (302°F). | ||
