P2483: EGT Sensor Circuit Range/Performance Bank 1 Sensor 5
The P2483 code indicates that the Engine Control Module (ECM) has detected a performance or range issue with the Exhaust Gas Temperature (EGT) sensor located in Bank 1, Sensor 5 (typically downstream of the diesel particulate filter or selective catalytic reduction system). This sensor monitors exhaust temperature to optimize regeneration and emissions control. The code sets when the sensor signal is outside expected parameters, often due to sensor degradation, wiring issues, or exhaust system problems.
01. Most Common Causes
- Faulty EGT sensor (Bank 1 Sensor 5)
- Damaged or corroded wiring/connector
- Exhaust leak near the sensor
- ECM software issues or calibration error
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced fuel economy
- Possible limp mode or reduced engine power
- Failed emissions test
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect the EGT sensor and wiring for damage or corrosion.
Step 3: Compare sensor resistance and voltage readings to manufacturer specifications.
Step 4: Check for exhaust leaks upstream of the sensor.
Step 5: If all else is normal, replace the EGT sensor.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is generally not recommended to drive long distances with this code, as it can lead to improper regeneration of the DPF or damage to the exhaust aftertreatment system. Short trips may be okay, but have it diagnosed promptly.
How much does it cost to fix?▼
The cost to replace an EGT sensor typically ranges from $50 to $150 for the part, plus labor (1-2 hours). Total cost can be $150-$400 depending on vehicle and shop rates.
