Código de avería P006E: 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 P006E and related codes when it detects a fault within the boost control system. The P006E DTC is activated when the ECM (Engine Control Module) detects a lower than desired electrical value within the "A" boost control supply voltage circuit.

Código de avería P0077: This code is a generic OBD-II powertrain code, that means it applies to all makes and models of vehicles (1996-newer), although specific repair steps may vary depending on the model. On vehicles equipped with variable valve timing (VVT), the Engine Control Module / Powertrain Control Module (ECM/PCM) controls the camshaft position by regulating the engine oil through the control solenoid to change the position of the camshaft. The control solenoid is commanded using a Pulse Width Modulated signal (PWM) from the ECM/PCM. The ECM/PCM monitors this signal and if the voltage is above specification, it will set this trouble code and illuminate the Malfunction Indicator Lamp (MIL). Bank 1 refers to the side of the engine with cylinder #1 – be sure to verify according to manufacturers specifications. The intake valve control solenoid is usually located on the intake manifold side of the cylinder head. This code is similar to codes P0075 and P0076. This code may also be accompanied by P0026.

On vehicles equipped with variable valve timing (VVT), the Engine Control Module / Powertrain Control Module (ECM/PCM) controls the camshaft position by regulating the engine oil through the control solenoid to change the position of the camshaft. The control solenoid is commanded using a Pulse Width Modulated signal (PWM) from the ECM/PCM.

On vehicles equipped with variable valve timing (VVT), the Engine Control Module / Powertrain Control Module (ECM/PCM) controls the camshaft position by regulating the engine oil through the control solenoid to change the position of the camshaft. The control solenoid is commanded using a Pulse Width Modulated signal (PWM) from the ECM/PCM. The ECM/PCM monitors this signal and if the voltage is out of specification or intermittent, it will set this DTC and illuminate the Check Engine Light / Malfunction Indicator Lamp (CEL/MIL). Bank 1 refers to the side of the engine with cylinder #1 – be sure to verify according to manufacturers specifications. The intake valve control solenoid is usually located on the intake manifold side of the cylinder head. This code is similar to codes P0076 and P0077. This code may also be accompanied by P0026.

Código de avería P0074: This generic powertrain/engine diagnostic trouble code typically applies to all OBDII equipped vehicles. The Ambient Air Temperature (AAT) sensor converts ambient air temperature into an electrical signal for the Powertrain Control Module (PCM). This input is used to modify air conditioning system operation and display outside air temperature. The PCM receives this input and possibly two more; Intake Air Temperature (IAT) and Engine Coolant Temperature Sensor (ECT). The PCM looks at the AAT sensor voltage and compares it to the IAT/ECT sensor readings when the ignition switch is first turned on after a long cool down period. This code is set if these inputs vary too much. It also looks at the voltage signals from these sensors to determine if they are correct when the engine is fully warmed up. This code is usually set due to electrical issues. Troubleshooting steps may vary depending upon manufacturer, type of AAT sensor and wire colors.
