Código de avería P00A1: This diagnostic trouble code (DTC) is a generic powertrain code, which means it applies to OBD-II equipped vehicles that have a charge air cooler temperature sensor (Chevy, Ford, Toyota, Mitsubishi, Audi, VW, etc.). Although generic, the exact repair steps may vary depending on make/model. A turbocharger is basically an air pump used to force air into the engine. Inside, there are two sections: the turbine and the compressor. The turbine is attached to the exhaust manifold, where it is driven by exhaust gases. The compressor attaches to the air intake. Both are connected by a shaft, so when the turbine spins, the compressor also spins, allowing intake air to be drawn into the engine. Cooler air provides denser intake charge to the engine and therefore more power. Because of this, many engines are equipped with a charge air cooler, also known as an intercooler. Charge air coolers can be either air-to-liquid or air-to-air coolers, but the function is the same – to cool air entering the intake. A charge air cooler temperature sensor (CACT), is used to measure the temperature and therefore the density, of air entering exiting the charge air cooler. This information is sent to the powertrain control module (PCM) where it is compared to intake air temperature (and in some cases engine coolant temperature and exhaust gas recirculation temperature) to determine charge air cooler performance. The PCM sends a reference voltage (usually 5 volts) through an internal resistor. It then measures the voltage to determine charge air cooler temperature. Note: Sometimes the CACT is part of the boost pressure sensor. Code P00A1 is set when the PCM detects a malfunction with the bank 2 charge air cooler temperature sensor. Bank 2 indicates the problem is with the second bank of the engine. That is, the bank that does not include cylinder #1.

Código de avería P00A8: 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 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 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.

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 P00A5: 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 #2 sensor on bank 2, a P00A5 will set. 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.
