What causes p0141 code on oxygen sensor heater?
Faulty oxygen sensor heater (most common) Circuit problems (e.g., damaged wiring, loose connections – fairly common) Issues with the PCM (e.g., software in need of an update – very rare) A circuit problem is one of the possible causes of the P0141 code.
What to do if your car has a p0141 code?
If the OBD-II scanner indicates a P0141 trouble code, bring your vehicle to the nearest auto repair shop. A technician can determine if the fault lies with the oxygen sensor or somewhere else.
What does DTC p0141 stand for in heater?
DTC P0141 stands for “Oxygen Sensor Heater Circuit Malfunction (Bank 1, Sensor 2).” It indicates a problem with the heater circuit of engine bank 1’s downstream O2 sensor. This code is part of a family of codes, listed as follows:
What causes incorrect readings on the O2 sensor?
A leak in the exhaust system before the (O2) sensor will also cause incorrect readings. The only other possibilities are wiring issues, and computer concerns. A leaking or faulty fuel injector
How is the p0141 O2 sensor trouble code?
How serious is the P0141 code? 1 The code is for the sensor behind the catalyst on the bank 1 of the engine. 2 O2 sensors are the fuel control feedback the ECM needs to properly control the injectors. 3 The ECM may stay in open loop until the O2 system is repaired or the O2 sensor starts working again.
What does the DTC code p0141 stand for?
DTC P0141 stands for “Oxygen Sensor Heater Circuit Malfunction (Bank 1, Sensor 2).” It indicates a problem with the heater circuit of engine bank 1’s downstream O2 sensor. Make sure you know bank 1 from bank 2 before you start clearing any of the codes.
How to check an O2 sensor fault code?
1 Clearing the fault codes and performing a road test to try and verify a failure 2 Replacing the O2 sensor for bank 1 sensor 2 3 Repairing or replacing the wiring or connection to the O2 sensor for bank 1 sensor 2 4 Replacing the fuse to the heater circuit for the O2 sensor heater circuit
What should I do if my oxygen sensor is not working?
Start by checking the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. What does this mean? The code means that there is a problem with the heater element circuit of the heated oxygen sensor.

What does p0141 mean in Powertrain Control Module?
Code P0141 occurs when the powertrain control module tests the downstream heated oxygen sensor’s heater circuit on Bank 1 and detects a short in the circuit or excessive resistance in the heater circuit. P0141 Symptoms Check Engine Light is on
DTC P0141 stands for “Oxygen Sensor Heater Circuit Malfunction (Bank 1, Sensor 2).” It indicates a problem with the heater circuit of engine bank 1’s downstream O2 sensor. This code is part of a family of codes, listed as follows:
How does the PCM work with the O2 sensor?
The PCM uses data from the upstream O2 sensor (the one before the converter) to fine-tune the engine’s air-fuel mixture. Meanwhile, the PCM uses data from the downstream O2 sensor (the one after the converter) to determine converter efficiency.
