A P2659 trouble code means that the Powertrain Control Module (PCM) has detected a short in the rocker arm actuator control circuit. More specifically, this trouble code signifies that the problem happened in the intake camshaft in engine bank 2, which the mechanic can find on the intake side of the cylinder head in engine bank 2 or the bank where the number one cylinder is not located. In addition to a P2659 trouble, a mechanic can also find the following related codes, including P2655, P2656, P2567, and P2568.
When a P2659 trouble code is stored, the PCM has detected an abnormal voltage reading from the rocker arm actuator control circuit that varies by more than 10 percent than a level recommended by the manufacturer. This, in turn, causes the storage of the code on the PCM and the illumination of the Check Engine light.
Some common causes of a P2659 trouble code include low oil level or low oil pressure, a malfunctioning oil control valve, a short in an electric circuit or connector associated with the oil control valve, and a bad PCM.
Rough idling, reduced engine performance, and hesitation while accelerating are common symptoms of a P2659 trouble code.
To diagnose a P2659 trouble code, a mechanic needs a manufacturer's service manual, advanced scan tool, and a digital volt/ohmmeter. The mechanic should complete the following steps when diagnosing this code:
A common mistake made by mechanics diagnosing a P2659 trouble code is to replace engine components when the problem actually lies with a low oil level, pressure, or viscosity.
When driving that is subject to a P2659 trouble code, vehicle owners can expect to experience trouble accelerating, a reduction in engine performance, and a rough idle.
