Bank 2 sensor 1. That's driver's side front.
P0153 OBD-II Trouble Code
Technical Description
Oxygen Sensor Circuit Slow Response (Bank2, Sensor1)
What does that mean?
This involves the oxygen sensor upstream the catalytic converter on Bank 2. This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use.
Symptoms
You will likely not notice any drivability problems, although there may be symptoms.
Causes
A code P0153 may mean that one or more of the following has happened:
The oxygen sensor is faulty
The wiring to the sensor is broken / frayed
There is an exhaust leak
Possible Solutions
Things that may fix the problem include:
Check and fix any exhaust leaks
Check for wiring problems (shorted, frayed wires)
Check the frequency and amplitude of the oxygen sensor (advanced)
Check for a deteriorating / contaminated oxygen sensor, replace if necessary
Check for inlet air leaks
Check the MAF sensor for proper operation
Replace the Bank 2 oxygen sensor upstream of the catalytic converter
