Error Code P0141: O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 2. Error code P0141 is described as Oxygen Sensor Heater Circuit Malfunction (Bank 1, Sensor 2). This means there is a problem on the O2 sensor on bank 1, and it fails to decrease the time needed to enter closed loop.

What does the DTC code p0155 stand for?

Diagnostic trouble code (DTC) P0155 stands for ”O2 Sensor Heater Circuit Malfunction (Bank 2, Sensor 1).” It is triggered when the vehicle’s computer or the engine control module (ECM) detects an unexpected voltage condition or excessive current draw on the heater circuit of your vehicle’s Bank 2 HO2.

What is the error code for bank 1 O2 sensor?

Error Code P0141 by definition means the heated circuit of the bank 1 O2 sensor reduces the time required to make a closed loop. As the Oxygen sensor reaches the temperature needed to operate, the O2 sensor responds by changing according to the O2 content of the exhaust around it.

What does the DTC code p0135 stand for?

Diagnostic trouble code (DTC) P0135 stands for “Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1).” It is set when the car’s primary computer—also called the powertrain control module or PCM—determines that the heated oxygen sensor (HO2S) 1 heater current is higher or lower than the ideal amp for a certain amount of time.
