Código de avería P0127: This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to all 1996-newer vehicles (Dodge, Chrysler, Hyundai, Jeep, Mazda, etc.). Although generic, the specific repair steps may vary depending on make/model. A stored code P0127 means that the powertrain control module (PCM) has detected an input signal from the intake air temperature (IAT) sensor circuit which is indicative of the temperature or circuit voltage being too high. The IAT sensor input and the mass airflow (MAF) sensor input signals are used by the PCM to calculate fuel delivery and ignition timing. Sustaining an air/fuel ratio of 14.7:1 is vital to engine performance and fuel efficiency; therefore the input of the IAT sensor is critical. The IAT sensor is typically inserted into the air inlet pipe or air cleaner box but it may also be threaded directly into the intake manifold. The IAT sensor may also be integrated into the MAF sensor housing. Regardless of design, 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 normally a two-wire thermistor sensor. As varying degrees of air flow across the cold wire element, sensor resistance varies according to temperature. In other words, the more air that flows across the cold-wire element, the lower the degree of temperature and resistance it provides. OBD II equipped vehicles generally use a reference voltage (five-volts is normal) and a ground signal with the IAT sensor completing the circuit. The varying degrees of resistance in the IAT sensor element create voltage fluctuations in the input circuit. These fluctuations are recognized by the PCM as variations in intake air temperature. If the PCM detects a level of voltage from the IAT sensor that is higher than the maximum allowable limit, a code P0127 will be stored and a malfunction indicator lamp (MIL) may be illuminated.

Brands of vehicles that may see this code include but are not limited to Pontiac, Toyota, Mazda, Dodge, Chevrolet, Honda, Jeep, Ford, VW, etc. Although generic, the specific repair steps may vary depending on make/model. This means that the engine’s powertrain control module (PCM) has detected that the engine has not reached the required temperature level within a specified amount of time after starting the engine. Often, the intent of the P0128 code is to indicate a faulty thermostat (likely stuck in the open condition). Similar codes: P0125

Código de avería P0129: This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to all 1996-newer vehicles (Dodge, Chrysler, Hyundai, Jeep, Mazda, etc.). Although generic, the specific repair steps may vary depending on make/model. When you find a P0129 code stored in your OBD-II equipped vehicle, it means that the powertrain control module (PCM) has detected a low barometric pressure reading from the barometric pressure sensor (BPS) or the manifold absolute pressure sensor (MAP). The barometric pressure sensor lets the PCM monitor changes in atmospheric pressure. Atmospheric pressure is related exactly to the particular degree of altitude, as it applies to your vehicle. This information is used by the PCM to help calculate fuel delivery and ignition timing strategy. The barometric pressure sensor is usually supplied with a reference voltage signal, a battery ground, and one (or more) output signal circuit/s. The BPS completes the reference voltage circuit and provides the appropriate resistance as determined by actual barometric pressure. As changes in atmospheric pressure occur, BPS resistance levels react accordingly. Fluctuating resistance in the BPS causes changes in sensor output voltage to the PCM. These changing voltage signals are not only used by the PCM to map fuel delivery and ignition timing strategy but also compared to programmed parameters for code storing. Because automakers uses varying designs for monitoring barometric pressure, you will need to consult your vehicle information source (All Data DIY is a good one) to determine the exact BPS design of your vehicle. Most manufacturers use a BPS that is separate from the MAP sensor. It is mounted away from the engine and typically has a vacuum hose connected to it. Some models use a system in which the BPS integrated with the MAP sensor. In this type of system, manifold absolute pressure is usually substituted for barometric pressure and the scanner data stream will reflect this terminology. If the PCM detects a BPS input signal that varies from comparison data by more than the programmed limit, a P0129 will be stored and a MIL will possibly be illuminated.

Código de avería P012A: This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles that have a turbocharger or supercharger inlet pressure sensor. Brand of vehicles may include but are not limited to Ford, Dodge, Saturn, Nissan, Subaru, Honda, etc. Although generic, the specific repair steps may vary depending on make/model/engine.

The inlet sensor works with the ECM (Electronic Control Module) or PCM (Powertrain Control Module) in order to monitor and regulate intake pressure. The "(Downstream of throttle valve)" indicates what specific inlet sensor has the malfunction and it’s location. The pressure sensor may also incorporate a temperature sensor into it.

Código de avería P011D: This generic powertrain diagnostic trouble code (DTC) typically applies to all OBD-II vehicles. That may include but is not limited to vehicles from Nissan, Toyota, Chevrolet, GMC, Ford, Dodge, Vauxhall, etc. Although generic, the exact repair steps may vary depending on make/model. A stored code P011D means that the powertrain control module (PCM) has detected a discrepancy in the correlating signals between the charge air temperature (CAT) sensor and the intake air temperature (IAT) sensor for engine bank number two. Bank 2 refers to the engine bank that does not contain the number one cylinder. As you can probably tell by the code description, this code is used only in vehicles that are equipped with forced air induction devices and multiple intake air inlet sources. Intake air inlet sources are called throttle bodies. Forced air induction devices include turbochargers and superchargers. CAT sensors are normally composed of a thermal resistor that protrudes from the housing on a wire pedestal. The resistor is positioned so that ambient air entering the engine intake, after leaving the intercooler (sometimes called the air charge cooler), may flow across it. The housing is normally designed to thread or bolt into a turbocharger/supercharger inlet pipe, near the intercooler). As charge air temperature increases, the level of resistance in the CAT resistor decreases; causing circuit voltage to move towards the reference maximum. The PCM sees these variations in CAT sensor voltage as changes in charge air temperature. The CAT sensor/s provides data to the PCM for boost pressure solenoid operation and boost pressure release valve operation, as well as certain facets of fuel delivery and ignition timing calculation. The IAT sensor acts in much the same manner as the CAT sensor; in fact, some early (pre OBD-II) computerized vehicle service manuals described the intake air temperature sensor as an air charge temperature sensor. The IAT sensor is positioned so that ambient intake air is drawn across it as it is enters the engine intake. The IAT sensor is located near the air filter housing or air inlet pipe. A code P011D will be stored and a malfunction indicator lamp (MIL) may be illuminated if the PCM detects voltage signals from the CAT sensor and the IAT sensor which differ by more than a preprogrammed degree. Multiple ignition cycles, with a failure, may be required for MIL illumination.

Código de avería P0130: 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 O2 sensor produces a voltage based on oxygen content in the exhaust. The voltage varies between .1 and .9 Volts, .1 indicating lean and .9 indicating rich. The ECM constantly monitors this voltage while in closed loop to determine how much fuel to inject. If the ECM determines that the O2 sensor voltage was too low (less than .4 Volts) for too long (for more than 20 seconds (time varies with model)), this code is set.
