Introduction: How a Faulty EGT Sensor Manifests
If you drive a Nissan NV400 or Renault Master, you may notice:
-
Check Engine Light illuminating
-
Reduced engine power or acceleration
-
Vehicle entering limp mode
-
Irregular DPF regeneration
-
Increased fuel consumption
A scan tool might reveal error codes P0544 or P0545, indicating an issue with the Exhaust Gas Temperature (EGT) Sensor, OEM part 8200921749. Recognizing these symptoms early can prevent serious turbo or DPF damage.
The Diagnosis: What P0544 / P0545 Mean
-
P0544 – Exhaust Gas Temperature Sensor Circuit (Bank 1 Sensor 1)
-
P0545 – Exhaust Gas Temperature Sensor Circuit Low
These codes indicate the ECU is receiving inaccurate or weak temperature signals from the upstream EGT sensor. A failing sensor may cause:
-
Engine underperformance
-
Interrupted DPF regeneration
-
Overheating risks for the turbo
-
Increased fuel consumption
-
Limp mode activation
Since the sensor operates in extreme heat, degradation over time is common.
The Solution: Replace the EGT Sensor (OEM 8200921749)
Replacing the EGT sensor is the most reliable fix.
OEM Number: 8200921749
