> ```
> * Ground terminals A and B (see diagram below) with the ignition "ON" and engine not running. The system will enter the diagnostic mode. In this mode, the computer will display a Code 12, three consecutive times, by flashing the "CHECK ENGINE", "SERVICE ENGINE SOON" or "MALFUNCTION INDICATOR LAMP" or light. A Code 12 consists of one flash, a short pause, then two flashes in rapid succession.
> * After Code 12 is displayed, any stored trouble codes will be displayed by flashing the "CHECK ENGINE", "SERVICE ENGINE SOON" or "MALFUNCTION INDICATOR LAMP" light. All codes are displayed 3 times each then a code 12 will repeat. In the diagnostic mode, the computer will also energize all computer controlled relays and solenoids.

awesome thank you, well i just pulled the code, it blinked 4 times then a pause, then it blinked 4 more times. any idea what code that is? i dont know how to read GM codes, only hondas lol 😛

> This is the description of a Code 44 as set on GM products It is an indication of a lean mixture as indicated by the oxygen sensor readings.
>
> Circuit description: The ECM supplies a voltage of about .45 volts between the appropriate terminals of the sensor. (If measured with a ten megohm DVM, this may read as low as .32 volt). The O2 sensor varies the voltage within a range of about one volt, if the exhaust is rich, down thru about .10 volt, if exhaust is lean.
>
> The sensor is like an open circuit and produces no voltage, when it is below about 360 degrees C, 600 degreeF. An open sensor circuit, or a cold sensor, causes Open Loop operation.
>
> Test description:
>
> 1.) Code 44 is set when the O2 sensor signal voltage remains below .3 volts for 50 seconds or more and the system is operating in “closed loop”.
>
> Diagnostic aides:
>
> The code 44 for lean exhaust is most likely caused by one or more of the following:
>
> 1.) O2 sensor wire - Sensor pigtail may be mispositioned and contacting the exhaust manifold.
>
> 2.) Check for an intermittent ground wire between connector and sensor.
>
> 3.) Poor ECM to engine block ground.
>
> 4.) MAF Sensor - A MAF sensor that causes the ECM to sense a lower than normal airflow will cause the system to go lean. Disconnect the MAF sensor. If the lean condition is gone then replace the MAF sensor.
>
> 5.) Vacuum leaks can cause a lean condition and/or possibly a high idle. Check for cracked hoses a bad gasket or a faulty EGR or PCV Valve.
>
> 6.) fuel pressure - system will go lean, if pressure is too low. It may be necessary to monitor fuel pressure while driving the car at various road speeds and/or loads to confirm.
>
> 7.) Clogged injector or lean injector - perform an injector balance test…
Let the testing begin

J&J, did you get that infor from a service manual/cd or similiar? If so what one? I need a some OBDI manuals.

is that the only code it had?
