P0152 Code - O2 Sensor Circuit High Voltage Bank 2 Sensor 1

What Does P0152 Mean?

The job of the Oxygen (O2) sensor is to measure the oxygen content in the exhaust. The PCM will then use that data to regulate the pulse of the fuel injector. The O2 sensor plays an important role for the engine’s proper operation. Any problem with it can cause the PCM to add or take away too much fuel as it doesn’t receive the right information from the O2 sensor voltage.

This code’s purpose is to track the time the Air Fuel Ratio sensor or O2 sensor takes to go from determining the fuel control system is in an open loop to rapidly switch over and below 450-millivolt set point, indicating the fuel control system is in closed loop. Therefore, the Error Code P0152 is set when there is a sustained high voltage signal from the O2 sensor for a specified amount of time, or the sensor was stuck too high or too low in rich position for too long.

What are the common causes of P0152 ?

• The engine control module (ECM) sees the voltage of the O2 sensor for bank 2 sensor 1 above 1.2 volts when the ECM has commanded the fuel to a targeted lean condition on that bank of the engine.
• The ECM detects the voltage high problem and turns on the Check Engine Light.

What are the symptoms of P0152 ?

Symptoms of a P0152 diagnostic trouble code may include:

• Hesitation upon acceleration
• Excessive exhaust leak
• Rich or lean exhaust
• The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.

How do you troubleshoot P0152 ?

The fix for this error code is pretty straightforward. If through your diagnosis you have determined that the O2 sensor for bank 2 sensor 1 is at fault, then you should replace it.

• Burned or shorted wiring and connectors should be repaired.
• Leaks in the injector or fuel pressure regulator should be fixed.

If you are experiencing lean or rich codes associated with this error code, then you should first focus on fixing those problems first, as they can cause the O2 sensor voltage readings to appear faulty when they are in fact, only reading it correctly.

The O2 sensor’s high voltage output may just be an over rich condition from a leaking or stuck open injector.

The PCM may not have the ability to control the air-fuel mixture if there is a leak in the fuel system or the oxygen sensor is shorted.
