P2035

Exhaust Gas Temperature Sensor Circuit Low Bank 2 Sensor 2

Q: 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.

Q: Can I just clear P2035?

It will return unless the sensor or its wiring is repaired, because the low reading persists.

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.
