Exhaust Gas Temperature Sensor Circuit Low Bank 1 Sensor 2
What it means
P2032 means the engine computer read an abnormally low voltage from exhaust gas temperature sensor 2 on bank 1. That sensor monitors exhaust heat to protect the catalytic converter and, on diesels, manage particulate-filter regeneration. The engine runs normally; the fault is typically a shorted sensor, damaged wiring near the hot exhaust, or a bad connector.
Can I keep driving? Yes — the engine runs and drives normally. This is an exhaust-temperature sensor fault; on diesels it can disrupt DPF regeneration, so don't leave it unrepaired.
Real-world scan data
Figures reflect only diagnostic scans recorded through our own apps and tools. Cars are typically scanned because a symptom or warning light prompted it, so these counts describe our scan records — not the incidence of faults in any model, and not the quality, reliability, or safety of any vehicle.

Common symptoms
What you'll notice
- Check-engine light on
- Usually no change in how the car drives
- On diesels, disrupted or missed DPF regeneration cycles
- Possible reduced converter/DPF protection
Common causes
Most likely first
- Faulty exhaust gas temperature (EGT) sensor 2 reading lowLikely
- EGT sensor harness open or shorted to groundCommon
- Poor or corroded connection at the sensor connectorCommon
- Damaged wiring routed near the hot exhaustLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check the EGT sensor 2 live reading against actual exhaust temperature.
- Inspect the sensor connector and harness (bank 1, sensor 2) for shorts to ground, opens, and heat damage.
- Repair or reroute damaged wiring away from the exhaust.
- Replace the EGT sensor if it reads low with good wiring.
- Clear the code and re-test after a full warm-up cycle.
