Exhaust Gas Temp Sensor Intermittent Bank 2 Sensor 1
The P2083 code indicates an intermittent signal from the exhaust gas temperature (EGT) sensor located in bank 2, sensor 1 (pre-catalyst). This sensor monitors exhaust temperature to protect the catalytic converter and DPF. An intermittent circuit fault means the signal is erratic or drops out, often due to wiring issues, connector corrosion, or a failing sensor. This can lead to incorrect temperature readings, affecting engine performance and emissions.
01. Most Common Causes
- Faulty EGT sensor
- Damaged wiring or connector
- Corrosion in sensor connector
- Exhaust leak near sensor
02. Symptoms You Will Notice
- Check Engine Light on
- Reduced fuel economy
- Possible limp mode activation
- Increased emissions
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect EGT sensor wiring and connector for damage or corrosion.
Step 3: Test sensor resistance and compare to manufacturer specs.
Step 4: Check for exhaust leaks upstream of sensor.
Step 5: Clear code and test drive to see if it returns.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can cause catalytic converter or DPF damage. Short trips may be okay, but have it diagnosed promptly.
How much does it cost to fix?▼
Typically $50-$150 for diagnosis and sensor replacement, but costs vary by vehicle and labor rates.
