Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 2
What it means
P2036 means the ECM saw a high-voltage (out-of-range) signal from the exhaust gas temperature sensor at bank 2, sensor 2 — the reading corresponds to an implausible temperature, indicating an open circuit or wiring fault rather than a real over-temperature. These sensors help protect the catalyst or manage diesel particulate filter regeneration. The car usually drives normally, but the fault should be repaired so exhaust temperature is monitored correctly.
Can I keep driving? Safe to drive — this is a sensor-circuit fault with usually no noticeable change in how the car runs, though diesels may limit regeneration until fixed.
Common symptoms
What you'll notice
- Check-engine light on (often the only symptom)
- Exhaust gas temperature reads implausibly high or out of range on a scan tool
- On diesels, disabled or delayed diesel particulate filter (DPF) regeneration
Common causes
Most likely first
- Faulty exhaust gas temperature (EGT) sensor on bank 2, sensor 2 — most commonLikely
- Open or short-to-voltage in the EGT sensor wiring/harnessCommon
- Corroded or loose connector at the sensorCommon
- Rarely, an ECM/PCM faultLess often
How to diagnose & fix
Work through it in order
- Scan the live EGT sensor value; a reading pinned high or at circuit maximum confirms the open/high fault.
- Inspect the sensor's connector and harness for corrosion, damage, or an open near the hot exhaust.
- Measure the sensor's resistance and compare to the service-manual spec for its temperature.
- Replace the EGT sensor if it's open or out of range, then clear and re-test.
