Can a ho2s heater cause a p0155 code?
From an open HO2S heater ground circuit to a defective HO2S heater, many issues can trigger the P0155 code. Unless you are an automotive expert, making an accurate diagnosis can be difficult. So it’s best to let a professional handle the task.
What is the O2 sensor heater circuit for bank 1?
The O2 sensor heater circuit for bank 1 sensor 2 is used to heat the internal parts of the O2 sensor on bank 1 sensor 2 only, and the code can be isolated just to this sensor. Need help with a P0141 code? YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle.
What are the symptoms of the O2 sensor heater circuit?
The ECM tests the O2 sensor heater circuits at first startup and detects a short or open circuit, or an excessive current draw in the O2 bank 1 sensor 2 heater circuit. What are the symptoms of the P0141 code? The engine may run excessively rich since the engine is in open loop.

Can a heated oxygen sensor cause a malfunction?
If you drive a fairly modern vehicle, it might be equipped with a heated oxygen sensor (HO2) instead of a regular oxygen sensor. The former contains a heating element that brings the sensor up to operating temperature faster than the latter. However, HO2s are not invulnerable and can trigger a host of trouble codes, including a P0155.

P0143 Meaning The rear heated oxygen sensor (or sensor 3 for some vehicles), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank. Even if switching characteristics of the heated oxygen sensor 1 are shifted, the air-fuel ratio is controlled to stoichiometric, by the signal from the heated oxygen sensor 3.
Where is heated O2 sensor fuse located?
The Heated Oxygen Sensors (HO2S) are located in the exhaust system. On some vehicles, one sensor is located up at the exhaust manifold(s) and the other sensor is located down at the catalytic converter.
What is the O2 sensor connected to?
The sensors are connected to the exhaust pipe in the engine, and when the oxygen/o2 sensors fail, the fuel efficiency can drop drastically. This happens due to gas loss. This will further cause the vehicle to have too much air and run ‘lean.’ This doesn’t only hamper the vehicle’s health but also creates a staggering amount of unwanted pollution.
