Code 12 is also used when the ECM is in Diagnostic mode (ALDL Terminal B grounded, key On, engine Off) to signal the beginning or end of a so-called 'diagnostic sequence'. Rating is available when the video has been rented. CTS is used to control fuel mixture, timing, idle speed, TCC and EGR operations among others. The ignition module also passes this signal to the ECM to enable sequential fuel injection.
Loading... So to avoid unpredictable hazards when fixing a vehicle based on it's DTC codes -- make sure you get a reliable OBD2 reader that'll thoroughly scan the vehicle for faults beyond It may have a cover over it, and may even say "Diagnostic Connector".

When the air is hot, the thermistor has a low resistance, which rises as the air temperature cools. The MAF sensor produces a frequency output; around 30 Hz at idle to 150 Hz under acceleration. The conditions for setting this code are: the coolant temperature reported is > 284 deg F (140 deg C), and the above condition is present for more than 20 seconds
This is the ALDL. Typical causes for this code include: 1) Poor or corroded connections between the ECM and the wastegate solenoid 2) Open or shorted solenoid 3) Defective, sticking or maladjusted wastegate linkage 4)
