What it means
The EGT sensor on bank 2 sensor 2 reads below the lower plausibility limit — short to ground or shorted sensor element.
At a glance
- Usually lights the check-engine light
- Affects emissions; the car can fail an emissions test
How it works
The Bank 2 Sensor 2 exhaust gas temperature sensor sends the control module a signal for exhaust temperature at its installed position. The module checks the signal against a lower electrical plausibility limit. P2035 sets when the Bank 2 Sensor 2 signal is too low, commonly due to a grounded signal circuit or sensor fault.
Common causes
Most likely first.
- Signal shorted to ground
- Connector pins corroded - high contact resistance
- Harness chafing through insulation
Symptoms
- Check-engine light
- Possible reduced engine performance
- Possible emissions-control or exhaust-system warning
How to diagnose it
- Check freeze-frame data and compare live Bank 2 Sensor 2 temperature with other EGT readings, including when the exhaust is cold.
- Locate Bank 2 Sensor 2 using service information and inspect the harness for chafing or insulation worn through near hot exhaust parts.
- Inspect the connector for corrosion, damaged pins, or poor contact that could pull the signal low.
- Test the Bank 2 Sensor 2 signal wire for a short to ground and check continuity in the circuit using the wiring diagram.
- Test the sensor element and circuit against the manufacturer's specification to identify whether the sensor or harness is responsible.
- After repair, clear the code and verify that Bank 2 Sensor 2 temperature responds plausibly as the exhaust warms.
Common fixes
- Clean and secure corroded or loose Bank 2 Sensor 2 connector terminals.
- Repair the Bank 2 Sensor 2 signal wire if it is shorted to ground or chafed.
- Replace the Bank 2 Sensor 2 EGT sensor if it fails the specified test.
- Repair damaged harness insulation or terminals in the sensor circuit.
Can I keep driving?
The vehicle may remain drivable, but the control module may lack reliable Bank 2 Sensor 2 temperature data for emissions management. If an exhaust warning or reduced performance appears, avoid heavy loads and arrange repair soon.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
