Código de avería P001E: This is a generic powertrain diagnostic trouble code (DTC) and typically applies to OBD-II vehicles. Vehicles affected may include but is not limited to Volvo, Chevrolet, Ford, Dodge, Porsche, Ford, Land Rover, Audi, Hyundai, Fiat, etc. Although generic, the exact repair steps may vary depending on year, make, model and powertrain configuration. The camshaft is responsible for the valves’ positions. It uses a shaft with lobes integrated in the design to a specific measurement (depending on engine manufacturer and model) to, when mechanically timed properly, precisely open and close valves at the optimal amount/speed. The crankshaft and camshaft are connected mechanically using different styles (e.g. belt, chain). In the code description, they mention the camshaft "profile". What they are referring to here, is the shape or the roundness of the lobe. Some systems use these adjustable lobes, I am going to call it, to precisely integrate a more efficient "lobe design" at given times. These are beneficial because, at different engine speeds and loads, having a different camshaft profile can increase volumetric efficiency among other benefits depending on operator demands. It is important to note, most times it is not another physical lobe rather, manufacturers mimic a "new lobe" by using varying strategies (i.e. switchable/adjustable rocker arm components). The letter "2" in the description is extremely valuable in this case. Not only could the camshaft be on either side, but there may be 2 shafts on each cylinder head. So it’s important to clarify which camshaft you are working with before proceeding. As far as banks go, bank 1 will be the one with cylinder #1. Most times, B refers to the exhaust camshaft and A refers to the intake camshaft. This all depends on which particular engine you are working with as there are countless different designs that will alter these diagnosis procedures depending which one you own. Refer to she manufacturer’s service manual for the specifics. The ECM (Engine Control Module) illuminates the CEL (Check Engine Light) with P001E and related codes when it detects a malfunction within the camshaft profile control circuit. P001E is set when there is an low electrical condition within the bank 2 circuit.

Código de avería P0022: This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles, including but not limited to Toyota, VW, Ford, Dodge, Honda, Chevrolet, Hyundai, Audi, Acura, etc. A P0022 code refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car’s PCM (powertrain control module) or ECM (engine control module). VVT is a technology used in the engine to allow it to get greater power or efficiency at different running points. That consists of a few different components but the P0022 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set. The "A" camshaft is either the intake, left, or front camshaft.

Código de avería P0027: This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles, including but not limited to Toyota, VW, Ford, Dodge, Honda, Chevrolet, Hyundai, Audi, Acura, etc. Specific repair steps may vary depending on the model. On vehicles equipped with variable valve timing (VVT), camshafts are controlled by hydraulic actuators fed by the engine oil system through control solenoids by the engine control module/powertrain control module (ECM/PCM). The ECM/PCM has detected the range of movement of the exhaust camshaft on bank 1 is out of specifications or not operating when commanded. Bank 1 refers to the side of the engine with cylinder #1 – be sure to verify which side is correct according to manufacturers specifications. The exhaust valve control solenoid is typically located on the exhast manifold side of the cylinder head. Note: This code may also be associated with codes P0078, P0079 or P0080 – if any of these codes exist, fix the solenoid problem before proceeding with diagnosing the circuit range/performance issue. This code is similar to codes P0026, P0028, and P0029.

Código de avería P0025: This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles, including but not limited to Toyota, VW, Ford, Dodge, Honda, Chevrolet, Hyundai, Audi, Acura, etc. A P0025 code refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car’s PCM (powertrain control module) or ECM (engine control module). VVT is a technology used in the engine to allow it to get greater power or efficiency at different running points. In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set. The "B" camshaft is either the exhaust, right, or rear camshaft. Bank 2 is the side of the engine that does not contain cylinder #1. This code is nearly identical to P0022.

Código de avería P0024: This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles, including but not limited to Toyota, VW, Ford, Dodge, Honda, Chevrolet, Hyundai, Audi, Acura, etc. A P0024 code refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car’s PCM (powertrain control module) or ECM (engine control module). VVT is a technology used in the engine to allow it to get greater power or efficiency at different running points. In this case, if the cam timing is above a set limit (over-advanced), the engine light will be illluminated and the code will be set. The "B" camshaft is either the exhaust, right, or rear camshaft. A P0024 trouble code is basically the same as a P0021 code, except this is for camshaft "B", not "A". Bank 2 is the side of the engine that does NOT contain cylinder #1.

Código de avería P0023: This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles, including but not limited to Toyota, VW, Ford, Dodge, Honda, Chevrolet, Hyundai, Audi, Acura, etc. A P0023 code refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car’s PCM (powertrain control module) or ECM (engine control module). VVT is a technology used in the engine to allow it to get greater power or efficiency at different running points. That consists of an oil control valve (OCV), also called a solenoid valve and other components. This source says it best: The camshaft position (CMP) actuator is controlled by the powertrain control module (PCM) through a high control circuit and a low reference circuit. The high control circuit carries a 12 volt pulse width modulated (PWM) signal from the PCM to the CMP actuator solenoid in order to control the amount of engine oil flow to the cam phaser. The low reference circuit is used as a return circuit. The PCM has the ability to monitor the functionality of the high control and the low reference circuit. If the PCM detects an open, a short to ground, or a short to voltage, DTC P0023 sets. The "B" camshaft refers to the exhaust, right, or rear camshaft (looking at the engine from the drivers seat). Bank 2 refers to the side of the engine that does not contains cylinder #1.

Código de avería P0021: This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles, including but not limited to Toyota, VW, Ford, Dodge, Honda, Chevrolet, Hyundai, Audi, Acura, etc. A P0021 code refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car’s PCM (powertrain control module) or ECM (engine control module). VVT is a technology used in the engine to allow it to get greater power or efficiency at different running points. That consists of a few different components but the P0021 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is above a set limit (over-advanced), the engine light will be illluminated and the code will be set. The "A" camshaft is either the intake, left, or front camshaft. A P0021 engine code is basically the same as a P0011 code, except this is for Bank 2, not Bank 1.

VVT is a technology used in the engine to allow it to get greater power or efficiency at different running points. That consists of an oil control valve (OCV), also called a solenoid valve and other components. Basically the check engine light and associated P0020 trouble code means that the voltage in the circuit has fallen below a set limit for a specific amount of time (varies by make/model/engine). Bank 2 is the side of the engine that doesn’t contain cylinder #1. Note: This DTC is nearly identical to P0010
