• The PCM monitors the input voltage from the exhaust gas pressure sensor while the engine is running. If the input voltage from the exhaust gas pressure sensor is less than 0.52 V, the PCM determines there is a malfunction in the exhaust gas pressure sensor circuit.
P2455 Exhaust gas pressure sensor circuit high input
• The PCM monitors the input voltage from the exhaust gas pressure sensor while the engine is running. If the input voltage from the exhaust gas pressure sensor is more than 4.81 V, the PCM determines that there is a malfunction in the exhaust gas pressure sensor circuit.
P2456 Exhaust gas pressure sensor circuit intermittent/erratic
• The PCM monitors the input signal from the exhaust gas pressure sensor. If the differential pressure between the maximum and minimum value of the exhaust gas pressure sensor is less than 90 Pa {0.68 mmHg, 0.027 inHg}, the PCM determines that there is a malfunction in the exhaust gas pressure sensor.
P2458 Diesel particulate filter regeneration duration
• The PCM calculates diesel particulate filter soot accumulation based on the exhaust gas pressure sensor signal. If the PCM calculates that soot accumulation amount is more than 8 g/L {0.50 lb/ft3}, the PCM determines the diesel particulate filter regeneration duration.
P2459 Diesel particulate filter regeneration frequency
• The PCM calculates mileage to the next oil replacement based on the vehicle driving conditions (engine load, frequency of the diesel particulate filter regeneration). If the calculated mileage reached necessary mileage of the oil replacement, the PCM stores DTC and turns the diesel particulate filter indicator light flash.
P252F Engine oil level too high
• The PCM calculates engine oil attenuation based on fuel injection amount during diesel particulate filter regeneration. If the calculated engine oil attenuation amount is more than 20 %, the PCM determines that the engine oil amount level is too high.
P253F Engine oil deteriorated
• The PCM calculates engine oil attenuation based on fuel injection amount during diesel particulate filter regeneration. If the calculated engine oil attenuation amount is more than 35 %, the PCM determines that the engine oil amount level is deteriorated.
P2621 Intake shutter valve position sensor circuit low output
• The PCM monitors the intake shutter valve position sensor circuit voltage while the engine is running. If the PCM detects the circuit voltage is less than 0.2 V, the PCM determines that there is a malfunction in the intake shutter valve position sensor circuit.
P2622 Intake shutter valve position sensor circuit high output
• The PCM monitors the intake shutter valve position sensor circuit voltage while the engine is running. If the PCM detects the circuit voltage is more than 4.82 V, the PCM determines that there is a malfunction in the intake shutter valve position sensor circuit.
U0166 Communication error to water heater unit
• PCM cannot receive any signals from water heater unit.
