2010 Malibu

Possible causes po201...> - Faulty fuel injector 1 - Fuel Injector 1 harness is open or shorted - Fuel injector 1 circuit poor electrical connection When is the code detected? If an electrical malfunction occurs in the fuel injector circuit for engine cylinder #1, the ignition feed driver signals the Powertrain Control Module (PCM) to set the P0201 code. Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light) - Lack/Loss of Power - The engine may be harder to start - Engine hesitation P0201 Chevrolet Description The Powertrain Control Module (PCM) controls the fuel injectors by using an ignition feed driver and ground circuit within the PCM. The driver has the ability to detect an electrical malfunction in the ignition feed or ground circuit......>P0013 CHEVROLET - Exhaust Camshaft Position Actuator Solenoid Control Circuit P0013 Chevrolet Possible causes - Dirty Oil - Low engine oil level - Faulty Exhaust Camshaft Position Actuator Solenoid - Exhaust Camshaft Position Actuator Solenoid harness is open or shorted - Exhaust Camshaft Position Actuator Solenoid circuit poor electrical connection - Faulty Engine Control Module (ECM) Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light) P0013 Chevrolet Description The Camshaft Position (CMP) actuator is attached to each camshaft and is hydraulically operated in order to change the angle of the camshaft relative to Crankshaft Position (CKP). The CMP actuator solenoid is controlled by the control module. The control module sends a pulse width modulated 12-volt signal to a CMP actuator solenoid. The solenoid controls the amount of engine oil flow to a CMP actuator. The CMP actuator can change the camshaft angle a maximum of 25 degrees. The control module increases the pulse width to accomplish the desired camshaft operation.
