id0140f1223300
• Exhaust gas temperature sensor (upper): Detects the exhaust gas temperature before it flows to the oxidation catalyst to check if the temperature is within the catalytic activity range.
• Exhaust gas temperature sensor (middle): Detects the exhaust gas temperature before it flows to the diesel particulate filter to check if the temperature is at the target temperature for diesel particulate filter manual regeneration.
• Exhaust gas temperature sensor (lower): Checks if particulate matter is burned abnormally in the diesel particulate filter.
