Código de avería P00A6: This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model. The IAT (Intake Air Temperature) sensor is a thermistor that varies resistance based upon the temperature of the engine intake air. It is typically located in the air intake ductwork and is usually a two wire sensor. One wire is supplied 5 Volt from the PCM (Powertrain Control Module) and the other is a ground. The powertrain control module (PCM) monitors the change in the 5 volt supplied to determine air temperature to run the engine at the most efficient conditions possible at the given temperature. When the intake air is cold, the resistance is high, resulting in a high signal voltage. Conversely, when the intake air is warm, the resistance is low, resulting in a low signal voltage. This code means that the PCM saw a larger-than-normal change in a shorter-than-expected time on the #2 IAT signal circuit on bank 2. Bank 2 is the side of the engine that does not contain cylinder #1.

Código de avería P00A7: This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model. The IAT (intake air temperature) sensor simply measures the temperature of air that is entering the engine. Intake air temperature is important because the higher the intake air, the higher the combustion temperatures. High combustion temperatures result in increased Nox (Nitrogen oxides) emissions. To keep these higher temps from causing increased combustion temps, the intake air tubing should be intact, allowing the engine to «breathe» air that isn’t sampled from the engine compartment. The IAT sensor measures air temp by using a thermistor, or a thermometer of sorts. The thermistor is supplied 5 volts reference voltage from the PCM (powertrain control module) and a ground. Usually, when the air temperature is cold the resistance in the thermistor is high and when the air temperature is warmer, the resistance decreases. This change in resistance changes the 5 V reference from the PCM, thereby informing the PCM of the temperature of incoming air. If the PCM notices that the incoming bank 2 air temp sensor #2 is unusually high, say, 300 degrees, when the engine temp is still relatively low, it will set a P00A7. Bank 2 is the side of the engine that does not contain cylinder #1.

Although generic, the specific repair steps may vary depending on make/model. The powertrain control module (PCM) monitors the temperature of the air entering the engine. The PCM supplies a 5 volt reference voltage to the Intake Air Temperature (IAT) sensor The IAT is a thermistor that varies resistance based on temperature. As the temperature increases, resistance decreases. Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts for the #2 IAT sensor, it sets this P00A8 check engine light code. Bank 2 is the side of the engine that does not contain cylinder #1.

Código de avería P00A9: This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to all 1996-newer vehicles (Ford, Mazda, Mercedes Benz, etc.). Although generic, the specific repair steps may vary depending on make/model. A stored code P00A9 means that the powertrain control module (PCM) has detected an intermittent input signal from the #2 intake air temperature (IAT) sensor circuit on bank 2. Bank 2 is the side of the engine that does not contain the number one cylinder. The PCM uses the IAT input signal and the mass airflow (MAF) sensor input signal to calculate fuel delivery and ignition timing strategy. Since maintaining a correct air/fuel ratio (typically 14:1) is critical to engine performance and fuel efficiency, the input of the IAT sensor is very important. The IAT sensor can be threaded directly into the intake manifold but is more commonly inserted into the air inlet pipe or air cleaner box. Some manufacturers also integrate the IAT sensor into the MAF sensor housing. At any rate, it must be positioned so that (with the engine running) ambient air, drawn into the intake manifold through the throttle body, can continuously and consistently flow across it. The IAT sensor is usually a two-wire thermistor sensor. Sensor resistance varies according to the temperature of the air that flows across the cold wire element. Most OBD II equipped vehicles utilize a reference voltage (five-volts is normal) and a ground signal to complete the IAT sensor circuit. The varying resistance levels in the IAT sensor element cause voltage fluctuations in the input circuit. These fluctuations are interpreted by the PCM as changes in intake air temperature. If the PCM detects a certain number of intermittent signals from the bank 2 number 2 IAT sensor, over a set period of time, a code P00A9 will be stored and a malfunction indicator lamp may be illuminated.

Código de avería P00AA: This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model. The IAT (Intake Air Temperature) sensor is a thermistor, which basically means it measures air temperature by detecting resistance in the air. It’s usually located somewhere in the intake air ductwork, but can be located in the intake manifold on some applications. It is usually a two wire sensor supplied with a 5 volt reference wire (which also acts as a signal wire) from the PCM (Powertrain Control Module) and a ground wire. As air passes over the sensor the resistance changes. This change in resistance affects the 5 Volts supplied to the sensor accordingly. Colder air causes higher resistance and higher signal voltage & warmer air lower resistance and lower signal voltage. The powertrain control module (PCM) monitors this change in the 5 Volts and calculates air temperature to help operate the engine at the most efficient point possible at any given temperature. If the PCM detects a voltage that is out of normal operating range for the IAT sensor on bank 2, a P00AA will set. Bank 2 is the side of the engine that does not contain cylinder #1.

Código de avería P00AF: This is a generic powertrain diagnostic trouble code (DTC) and typically applies to OBD-II vehicles. That may include but is not limited to vehicles from Chevy (Chevrolet), GMC (Duramax), Dodge, Ram (Cummins), Isuzu, Ford, Vauxhall, VW, etc. Although generic, the exact repair steps may vary depending on year, make, model and powertrain configuration. Turbochargers, superchargers, and any other forced induction (FI) systems for that matter, use energy generated from the engine (i.e.: exhaust pulses, belt-driven screw-type, etc.) to increase the amount of air that can be introduced to the combustion chamber (increased volumetric efficiency). Given the fact that, in forced induction systems, intake pressures need to vary and need to be adjusted according to the operator’s many power needs. Manufacturers use a form of boost control valve (AKA, Waste-gate, boost control solenoid, etc.), which is monitored and controlled by the ECM (Engine Control Module), to make sure the air/fuel mixture is stoichiometric (ideal). It does this, by mechanically adjusting the "vanes" in the charger. These vanes are responsible for adjusting the amount of boost (intake pressure) to the chamber. As you can imagine, a problem within the boost controlling component, may cause drivability issues. The problem is, when the ECM loses control of the boost, typically, your vehicle goes into "limp" mode to avoid engine damage (via over/under-boost conditions causing a potentially damaging rich and/or lean A/F mixture). As far as the letter "A" goes here, it could be to distinguish a connector, wire, circuit group, etc. That said, the manufacturer’s specifications is the best resource you could have for this. The ECM illuminates the check engine light (CEL) with P00AF and related codes when it detects a fault within the boost control system. The P00AF DTC is activated when the ECM (Engine Control Module) detects the "A" boost control module operating abnormally (outside of the normal range). A turbocharger and related components:
