P2035 — Exhaust Gas Temperature Sensor Circuit Low Bank 2 Sensor 2
P2035 — Exhaust Gas Temperature Sensor Circuit Low Bank 2 Sensor 2. A fault in the sensor and actuator circuits. The car is usually drivable while you plan the repair. Typical causes: control module driver fault, blown fuse feeding the circuit, faulty sensor or actuator of the affected circuit.
powertrain (engine/transmission)
Is it safe to drive?
Short-term driving is OK In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.
How to diagnose with an OBD scanner
- Read the code and freeze frame Connect an OBD2 scanner, confirm P2035 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
- Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
- Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the exhaust gas temperature sensor circuit low bank 2 sensor 2 for damage, corrosion, chafing or poor contact.
- Subsystem check Measure reference voltage, ground and signal continuity at the component connector.
- Subsystem check Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
- Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2035 does not return.
Approximate repair cost
Repair cost depends on which component actually failed. Typical scenarios for P2035 (parts and labor, USD, independent shop rates): Repair wiring or connectors: $80–$250; Control module repair: $300–$1,000; Replace the faulty sensor or actuator: $150–$500. Overall, fixing P2035 usually costs between $80 and $1,000. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.
Common questions
Will P2035 clear itself?
Sometimes P2035 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.
What are the symptoms of P2035?
Drivers most often notice: increased fuel consumption in some cases, Check Engine Light on, possible limp mode depending on the affected component, the affected system operates intermittently or not at all.
How much does it cost to fix P2035?
Repair wiring or connectors — $80–$250; Control module repair — $300–$1,000; Replace the faulty sensor or actuator — $150–$500. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

How do I diagnose P2035 myself?
Start with a scan: confirm P2035, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the sensor and actuator circuits, and verify the suspect component against live data before buying parts.
What does P2035 mean?
Seeing P2035 on your scanner? The control unit has caught the sensor and actuator circuits operating outside its calibrated window. The formal description is “Exhaust Gas Temperature Sensor Circuit Low Bank 2 Sensor 2”, and the code is grouped under powertrain (engine/transmission) faults.
In this definition, “Bank 2” is the side of the engine opposite to cylinder 1 and “Sensor 2” is the downstream (after the catalytic converter) sensor. Mixing up banks and sensor positions is the most common DIY mistake with this code — verify the physical location before replacing anything.
To set P2035, the control module compares live readings of the sensor and actuator circuits against calibrated limits, usually over several drive cycles. Alongside the code it stores a freeze frame — a snapshot of rpm, load, coolant temperature and vehicle speed at the moment of failure. Reading that snapshot first saves diagnostic time.
Common symptoms of P2035
- increased fuel consumption in some cases
- Check Engine Light on
- possible limp mode depending on the affected component
- the affected system operates intermittently or not at all
What causes P2035?
- control module driver fault
- open or shorted wiring in the circuit
- faulty sensor or actuator of the affected circuit
- blown fuse feeding the circuit
- corroded, loose or damaged connector
