Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 2
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
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.
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.
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
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
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.
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.
