P2035 - EXHAUST GAS TEMPERATURE (EGT) SENSOR CIRCUIT LOW VOLTAGE BANK 2 SENSOR 2
POST UPDATED IN November, 2021
Description of DTC code P2035 Generic
The diagnostic code P2035 OBDII refers to the Exhaust Gas Temperature Sensor or EGT, which is placed in the front pipe of the Catalytic Converter (TWC). Its function is to protect the TWC from damage from the excessive heat that it is exposed to. This code indicates that the EGT Sensor circuit has a low voltage condition.
The Exhaust Gas Temperature Sensor is a resistance that changes to heat. It turns the exhaust temperature into an electrical signal that is sent to the Powertrain Control Module(PCM). The PCM gives you a 5-volt reference through a wire, and another wire provides the ground.
