Código de avería P00B3: This generic powertrain diagnostic trouble code (DTC) typically applies to all OBD-II vehicles. That may include but is not limited to vehicles from Mercedes, Vauxhall, Nissan, BMW, Mini, Chevy, Mazda, Honda, Acura, Ford, etc. The cooling system is an integral part of your vehicles engine system. It is responsible for not only monitoring your engine’s temperature but also regulating it. It does this using various electrical and mechanical systems/components including but not limited to: Coolant Temperature Sensor (CTS), radiator, water pump, thermostat, etc. The Engine Control Module (ECM) uses the CTS’ values to monitor the engine’s temperature and in turn, can regulate it accurately. Different temperatures require different air/fuel mixtures so it is imperative that the CTS is functioning within desired ranges. Most times, CTS’ are Negative Temperature Coefficient sensors, which means, the resistance within the sensor itself decreases as the temperature rises. Understanding this will help you greatly when troubleshooting. The ECM activates P00B1 and associated codes when it monitors one or multiples condition outside a specific electrical range within the CTS or it’s circuit. The ECM may detect an issue that is not consistent which comes and goes (P00B5) From my experience, the culprit here tends to be mechanical. Keep in mind, electrical faults could be the cause as well. P00B3 Radiator Coolant Temperature Sensor Circuit Low code is set when the ECM monitors a low specific electrical value within the radiator CTS or it’s circuit. It is one of five related codes, which are P00B1, P00B2, P00B3, P00B4, and P00B5.

Código de avería P00A2: 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 P00A2 is set when the PCM detects a low charge air cooler temperature sensor signal. This usually indicates the circuit is shorted. 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 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 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 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 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 P00B0: 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 "B" 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 P00B0 and related codes when it detects a fault within the boost control system. The P00B0 DTC is activated when the ECM (Engine Control Module) detects the "B" boost control module operating abnormally (outside of the normal range). A turbocharger and related components:
