pontiac g6 low cat efficiency bank one

WelcomeCustomer This is a basic code with usually one fix. That is to replace the converter. I would speak to your dealer because the converters are usually covered to 100,000 miles. Please ask if you need more information.

WHY WOULD CAT BE BAD IF ONLY 1950 MILES ON IT,THE CAR IS AN R TITLE SO IT IS NOT COVERED UNDER WARRANTY
Expert:  GM Tech (Cam) replied 5 years ago.
What year is the car?
Customer: replied 5 years ago.
07
Expert:  GM Tech (Cam) replied 5 years ago.

Ok, I did not expect it to be a 07 and have that code. I did search for bulletins and there is one about an exhaust leak that may be setting that code. Below is a copy. Also, I am from Canada so I am not sure what you mean by an "R" title.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

The customer may have a concern of the MIL being illuminated. The vehicle may a DTC P2097, P2099. P2096, P2098, P0420 or P0430

Recommendation/Instructions:

If following eSI diagnostics does not correct concern then this may be an exhaust leak. This leak may be very small and hard to locate. The ultrasonic leak detector J-41416 may assist in finding the leak. Be sure to check the seal between the exhaust pipe and converter. Also the welds around the HO2 sensor fitting may have pinholes.

WE CLEAR THE CODE IT USUALLY TAKES ABOUT 3 DAYS FOR LIGHT TO COME BACK ON ,IS THERE A REASON FOR THAT
Expert:  GM Tech (Cam) replied 5 years ago.

IT could take 3 drive cycles to set the code. Below is some information on the code.

Circuit/System Description

Important: A new converter with less than 100 miles on it may set DTC P0420 or P0430 due to out-gassing of the internal matting. Operating the vehicle at highway speeds for approximately 1 hour may correct the condition.

A 3-way catalytic converter (TWC) controls emissions by converting hydrocarbons (HC) and carbon monoxide (CO) into carbon dioxide (CO2), and oxides of nitrogen (NOx) into nitrogen. The TWC also stores oxygen. When the listed idle conditions follow the listed driving conditions, the Catalyst System Efficiency test will run. The engine control module (ECM) monitors this oxygen storage capacity by comparing the pre and post-catalyst oxygen sensor signals while adding and subtracting fuel during specific idle conditions. The ECM compares the pre and post-catalyst-oxygen sensor signals to determine if the oxygen storage capacity of the catalyst is degraded.

Conditions for Running the DTC

  1. Driving Conditions
    DTCs P0030, P0036, P0050, P0053, P0054, P0056, P0059, P0060, P0068, P0101, P0012, P0103, P0107, P0108, P0112, P0113, P0116, P0117, P0118, P0120, P0121, P0122, P0128, P0131, P0132, P0133, P0134, P0135, P0137, P0138, P0140, P0141, P0151, P0152, P0153, P0154, P0155, P0156, P0157, P0158, P0160, P0161, P0171, P0172, P0174, P0175, P0201, P0202, P0203, P0204, P0205, P0206, P0220, P0222, P0223, P0300, P0325, P0327, P0332, P0335, P0336, P0340, P0341, P0442, P0443, P0446, P0449, P0455, P0496, P0506, P0507, P1133, P1153, P1258, P1516, P2101, P2119, P2120, P2122, P2123, P2125, P2127, P2128, P2135, P2138, P2176, P2A00, P2A01, P2A03, P2A04 are not set.
    The engine has been running for more than 10 minutes.
    The vehicle has been driven at more than 1,000 RPM for more than 1 minute.
    The vehicle is in Closed Loop.
    The vehicle has Fuel Trim Learn enabled.
    The engine coolant temperature (ECT) parameter is between 70-125°C (156-257°F).
    The barometric pressure (BARO) is more than 70 kPa.
    The catalytic converter calculated temperature is greater than or equal to 450°C (842°F).
    The intake air temperature (IAT) is between -20 and +85°C (-4 and +185°F).
    The battery voltage is more than 11 volts.
  2. Idle Conditions
    The vehicle speed is less than 3.2 km/h (2 mph).
    For automatic transmissions, the transmission is in Reverse, Drive, or Low.
    The throttle position (TP) indicated angle is 2 percent or less.
    The short term fuel trim (FT) is between -10 and +10 percent.
    This diagnostic attempts one test during each valid idle period when the above conditions have been met. This diagnostic attempts up to 6 tests during each drive cycle.

Conditions for Setting the DTC

The control module determines that the efficiency of the catalyst has degraded below a calibrated threshold.
This diagnostic may conclude in one test attempt. However, this diagnostic may require as many as 18 test attempts which would require at least 3 drive cycles. Each test attempt may conclude in approximately 1 minute
