How is fault code P2033 fixed?

A typical diagnostic sequence used by mechanics, provided here for educational reference only. Diagnostic work should be performed by a qualified mechanic with the appropriate tools and training. 1. Read live data and look at the EGT sensor value. If it's pinned high or reading an impossible temperature with a cold engine, the circuit is the problem, not the exhaust 2. Unplug the sensor connector and inspect both halves for green corrosion, melted pins, or a lead that's been resting against the exhaust and burned through 3. Back-probe the connector and check for the expected voltage with the ignition on, then compare against your service data 4. Measure the sensor resistance with a multimeter. Most EGT sensors give a sensible reading at room temperature, and an open circuit (infinite resistance) confirms a dead sensor or broken lead 5. Wiggle-test the harness while watching live data. An intermittent jump in the reading points straight to a damaged wire rather than the sensor 6. Fit a new sensor if the wiring is sound, then clear the code and road-test long enough for the engine to reach full operating temperature

Can I keep driving?

Usually drivable, but get it diagnosed without delay.

What does it mean?

P2033 is a Powertrain (engine, transmission, fuel system) fault code. It indicates: Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 2 . This is a standardised OBD-II code. The technical definition is the same regardless of the make or model of vehicle, although specific causes and symptoms can vary between vehicles.
