P2034

Exhaust Gas Temperature Sensor Circuit Bank 2 Sensor 2

DTC P2034, sometimes indicated as P203400 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing exhaust gas temperature sensor circuit bank 2 sensor 2.

DTC P2034 is set when the PCM detects a problem with the exhaust gas temperature sensor circuit. Possible causes include a bad exhaust gas temperature sensor, a wiring problem, a bad PCM, or a problem with the powertrain control module (PCM) wiring harness.
If the exhaust gas temperature sensor is bad, replacing it should fix the problem. If there is a wiring problem, the wiring should be checked and repaired as needed. If the PCM is bad, it should be replaced. If there is a problem with the PCM wiring harness, the harness should be replaced.
