Exhaust Gas Temperature Sensor Circuit Intermittent Bank 2 Sensor 1
What it means
P2083 means the engine computer saw an intermittent or erratic signal from exhaust gas temperature sensor 1 on bank 2. That sensor monitors exhaust heat to protect the converter and, on diesels, manage particulate-filter regeneration. The engine runs normally, and because the fault comes and goes it usually points to a loose connector or chafed wiring rather than a dead sensor.
Can I keep driving? Yes — the engine runs and drives normally. This is an intermittent exhaust-temperature sensor fault; on diesels it can upset DPF regeneration, so fix it before it becomes constant.
Common symptoms
What you'll notice
- Check-engine light that comes and goes
- Usually no change in how the car drives
- On diesels, occasionally disrupted DPF regeneration
- Other intermittent EGT codes may appear
Common causes
Most likely first
- Intermittent or corroded connection at the EGT sensor (bank 2, sensor 1)Likely
- Chafed or heat-damaged wiring making occasional contactCommon
- Erratic exhaust gas temperature sensor 1 signalCommon
- Loose connector near the hot exhaustLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data to capture when the fault appears, and check the EGT sensor 1 live reading.
- Wiggle-test the sensor connector and harness on bank 2 to catch the intermittent dropout.
- Inspect wiring for chafing or heat damage near the exhaust; repair or reroute as needed.
- Reseat or replace a corroded connector; replace the EGT sensor if the signal is erratic with good wiring.
- Clear the code and drive several cycles to confirm.
