P2035
Exhaust Gas Temperature Sensor Circuit Low Bank 2 Sensor 2
Exhaust gas temperature (emissions)
Generic OBD-II
Low
What it means
P2035 means the exhaust gas temperature sensor at bank 2, position 2, is reading abnormally low voltage — usually a short to ground, an open circuit, or a failed sensor. This sensor helps protect the turbo and particulate filter, so the engine runs normally, but some vehicles pause DPF regeneration while it is faulted. Check the wiring, then the sensor itself.
Low
Can I keep driving? Safe to drive — the engine runs normally, though some vehicles limit diesel filter regeneration or turbo-protection while this sensor is faulted.
Common symptoms
What you'll notice
- Check-engine light on
- No noticeable change in how the engine runs
- On diesels, DPF regeneration may be disabled while the fault is present
Common causes
Most likely first
- Faulty exhaust gas temperature (EGT) sensor, bank 2 sensor 2Likely
- Harness shorted to ground or open in the sensor circuitCommon
- Poor or corroded electrical connection at the sensorCommon
How to diagnose & fix
Work through it in order
- Read freeze-frame data and view the EGT sensor 2 reading with a scan tool.
- Inspect the connector and wiring for a short-to-ground, open, or corrosion; repair as needed.
- Measure the sensor's resistance and compare against temperature spec.
- Replace the exhaust gas temperature sensor if it reads low with good wiring.
FAQ
Quick answers
Is it safe to drive with P2035?+
Yes. It is a monitoring-sensor fault, not a mechanical problem. On diesels, fix it promptly so the particulate filter can still regenerate.
Can I just clear P2035?+
It will return unless the sensor or its wiring is repaired, because the low reading persists.
