P0013 - CAMSHAFT POSITION ACTUATOR CIRCUIT "B" (BANK 1)

Thanks to the Variable Distribution System (VVT) or Variable Time of the Cam (VCT), the motor can have a greater power in its different points of operation. In this system is the valve OCV (Oil Control Valve) along with other components.

The CMP sensor (Camshaft Position Sensor) is inspected by the PCM (Power Train Control Module) by means of a low reference circuit and a high control circuit.

The high control circuit sends a signal modulated by pulse width, the value is 12 volts from the Powertrain Control Module to the solenoid of the CMP sensor actuator (Camshaft Position Sensor). This is to handle the quantity of oil flow coming from the engine to the cam frames. On the other hand, the return circuit is used as such by the low reference circuit. The PCM (Powertrain Control Module) monitors the good operation of the high control, as well as the low reference circuit. If the Powertrain Control Module (PCM) sense a strange behavior in the circuit, that is, short circuit to ground or voltage, the DTC code P0013 OBD II is established.

• Check Engine light turns on.
• Difficulty starting.
• The engine can stop.
• Low fuel consumption.

The circumstances that may cause the P0013 OBD2 fault code to be established are:

• Cables leading to the camshaft or OCV valve may be defective.
• Short circuit in the Oil Control Valve (OCV) solenoid.
• Defective OCV valve.

Do the following for a correct diagnosis and subsequent repair of diagnostic code P0013:

• Use a digital voltmeter to calculate the resistance at the Oil Control Valve terminals. Compare the results with the manufacturer's specifications, if not within that specified range, you must change the OCV valve.
• Also check the cables and connectors that go from the Oil Control Valve to the Powertrain Control Module (PCM). If you find defects in any of these components, repair or change as necessary.
