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.
What are the symptoms of a P0158 DTC?
Symptoms of a P0158 DTC may include: MIL (Malfunction Indicator Lamp) on Engine loses power and misses intermittently May exhibit loss of fuel efficiency Potential causes of an P0158 code include: Wiring in contact with exhaust components Engine running rich (If other codes are present)
What are the symptoms of a p2098 code?

Code P0138 means that your powertrain control module (PCM) has detected that the voltage signal from the rear O2 sensor is too high. What is an Oxygen Sensor? All modern cars have at least two oxygen sensors.
What does trouble code P0158 mean on an engine?
When trouble code P0158 is set, this indicates that there is a high voltage (steadily above .9 volts) for more than 10 seconds indicating a lack of oxygen in the exhaust stream and an abundance of fuel at sensor 2 on bank 2 of the engine. What Are the Symptoms of Code P0158?
What does O2 sensor error code p2098 mean?
This code means the PCM doesn’t have full control of the fuel as it should be since the O2 sensor is not giving the fuel control closed loop to control fuel correctly. Other O2 related codes that are also related to Error Code P2098 are:

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.
What is the code for the Check Engine light?
The C1201 code is the one that tells the vehicle to turn on the check engine light and disable the traction and VSC. Basically, when the other two codes pop up, this one is in charge of letting you know there’s a problem.
Why do I have two P0 codes on my car?

What does it mean when your check engine light is flashing?
Is the CEL Lit or Flashing? If the light is steadily lit, that means that one of your engine sensors is doing one of two things – it’s either sending a signal to the vehicle’s ECU that something is wrong, or the vehicle’s ECU (computer) itself has lost an accurate read on that particular sensor – meaning, the sensor has gone out.
