P2033 trouble code definition

Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 2

What the P2033 code means

P2033 is an OBD-II generic code for the exhaust gas temperature sensor circuit high bank 1 sensor 2 to the engine control module (ECM). This means the sensor signal voltage is shorted high on bank 1 sensor 2, indicating the temperature sensor is out of specified temperature range for a normal exhaust after the particulate filter on diesel engines

What causes the P2033 code?

  • The engine control module signal return from the bank 1 sensor 2 exhaust temperature sensor is out of range, in the high end.

  • The ECM turns on the Check Engine Light if the ECM detects a voltage return over approximately 3.3 volts for more than one second.

  • The wiring or connection to the sensor is shorted to power.

What are the symptoms of the P2033 code?

  • The Check Engine Light will be illuminated and the code is set in ECM memory as a fault.

  • The engine fault may be the P2033 and also particulate filter light may be illuminated.

  • If the particulate filter is clogged then you may have a low power condition.

How does a mechanic diagnose the P2033 code?

  • Scans and documents the code in the ECM

  • Diagnoses the code, as per the manufacturer's pinpoint test, to verify the sensor signal

  • Runs the particulate filter cleaning routine and retests the sensor

  • Disconnects the sensor and checks if the voltage short goes away on the scanner

Common mistakes when diagnosing the P2033 code

  • Clearing ECM memory codes before checking the freeze frame data of the failure

  • Failing to clear ECM codes after the P2033 codes are fixed

  • Replacing the sensor when a major exhaust restriction after the sensor is causing the excessive back pressure in the exhaust

How serious is the P2033 code?

Code P2033 is an indication that the particulate filter and sensor may need to be serviced and/or repaired. The particulate filter should be cleaned before the sensor is replaced.

What repairs can fix the P2033 code?

  • Replacing the sensor after the particulate filter is cleaned
  • Repairing the wiring or connection to the exhaust temperature sensor assembly
  • Replacing the ECM for a short circuit in the ECM temperature sensor circuit

Additional comments for consideration regarding the P2033 code

Code P2033 can be generated by a vehicle that has an exhaust that is partly blocked between the second temperature sensor and the exhaust outlet. A blocked particulate filter can also cause excessive exhaust temperatures.
