• ECU malfunction (rare)

How to Fix

1. Read all error codes with scanner
2. Check the voltage in the EGR temperature sensor circuit B with the ignition on
3. Inspect the wiring and connector for melts, insulation cracks, and oxidation.
4. Measure the resistance of the sensor (NTC thermistor) and compare with the table of values
5. Check the sensor ground circuit
6. Replace EGR temperature sensor B if the fault is confirmed
7. Clean the EGR system from carbon deposits if necessary.
