How many O2 sensors are on a Pontiac g6?
On yours there are 2 Oxygen sensors (O2) replace them both for best performance.
How many O2 sensors does a 2006 Pontiac g6 have?
Oxygen sensors are located before and after the catalytic converter. A vehicle may have two to five oxygen sensors, and sometimes even more.
What happens when you change the O2 sensor?
The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle’s computer. The ECU then adjusts the air-to-fuel ratio to optimize the fuel combustion. Sometimes an O2 sensor fails, and you need to replace it.
What is the code for 02 sensor circuit low voltage?
P0157 is a diagnostic trouble code (DTC) for “02 Sensor Circuit Low Voltage (Bank 2 Sensor 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
What is the code for check engine light?

What causes a p0056 problem on an oxygen sensor?
Potential causes of a P0056 trouble code may include: Open circuit inside oxygen sensor or open power or ground wires to oxygen sensor Exhaust system ground strap may have become corroded or broken PCM/ECM or oxygen sensor heater circuit wiring has failed Visually inspect the oxygen sensor wiring for damaged or loose wiring to the sensor.
Can a bad O2 sensor cause incorrect readings?
A leak in the exhaust system before the O2 sensor will also cause incorrect readings. And always check for after- market modifications. These can throw a wrench into the works! The only other possibilities (however unlikely), are wiring issues, computer concerns or a bad O2 sensor!
Are there any codes for an oxygen sensor?
There are a large number of codes relating to oxygen sensor faults. There are also a lot of faults that are often incorrectly thought to be caused by a bad oxygen sensor (also referred to as an O2 Sensor). The O2 codes relating to circuit faults can be tested fairly easily.
Why does my heater have a p0056 code?
Potential causes of a P0056 trouble code may include: Open circuit inside oxygen sensor or open power or ground wires to oxygen sensor. Exhaust system ground strap may have become corroded or broken. PCM/ECM or oxygen sensor heater circuit wiring has failed.
