What does P0156 mean?
Your Engine Control Module (ECM) uses the voltage levels provided by your O2 sensors to regulate your engine’s fuel injector pulse. If you are seeing code P0156, it means that the O2 sensor behind your catalytic converter on bank 2 is malfunctioning.
What is the p0156 code for bank 2?
A P0156 code refers to the Bank 2,2 o2 sensor or the downstream (post-cat) o2 sensor on Bank 2. It is a four wire sensor. The PCM supplies a ground circuit and a reference voltage circuit of about 0.5 volts.
What causes a p0156 code on an O2 sensor?
Potential causes of an P0156 code include: 1 Bad O2 sensor 2 Signal shorted to voltage 3 Wiring problems due to contact with exhaust components 4 Holes in exhaust near o2 sensor

What causes an engine to have a P0158 code?
Potential causes of an P0158 code include: Bad o2 sensor (Bank 2 Sensor 2) Wiring in contact with exhaust components. Engine running rich (If other codes are present) Holes in exhaust causing PCM to over-rich engine resulting in an abnormally high Bank 2, sensor 2 reading.
When is the p0156 code detected in a car?
Most auto repairs shops charge between $75 and $150 per hour. When is the P0156 code detected? The P0156 code is set when the Engine Control Module (ECM) detects that the rear O2 sensor signal voltage is out of range for an extended period of time.

What does the p0156 code on Bank 2 O2 mean?
It is capable of varying from about 0.1 to 0.9 volts, 0.1 V indicating lean exhaust and 0.9 V indicating rich exhaust. This P0156 code indicates that the Bank 2, 2 o2 sensor is stuck low for too long or isn\\’t active at all.
What does lean fault code p0171 mean on a car?
Your car or truck has either a P0171, P0174 lean fault code or both stored in the pc, these codes derive from Oxygen Sensor (O-2) readings. A lean code or codes suggest that there surely is too-much air in the exhaust.
