pontac G6 engine light stays on

Asked by Aug 17, 2013 at 05:55 PM about the 2009 Pontiac G6 GT

Question type: Maintenance & Repair

Engine light has been on for a week took the car to auto zone to have it put on the mechine they have and the code came up P0013 And P0014 I looked that up online and It said if that is the problem the the car would be running rough or stalling and its not it is running perfect from what I can tell

A P0013 code is generic and applies to all makes of vehicles. This DTC refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module). 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 P0013 sets. The "B" camshaft refers to the exhaust, right, or rear camshaft (looking at the engine from the drivers seat). Bank 1 refers to the side of the engine that contains cylinder #1.

A code P0013 may mean that one or more of the following has happened: Faulty oil control valve (OCV), Open or short in the OCV / solenoid valve, Damaged computer (PCM)

A code P0014 refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module, also called an ECM). That consists of a few different components but the P0014 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. Bank 1 is the side of the engine containing cylinder #1. The "B" camshaft shall be either the "exhaust," "right," or "rear" camshaft. Left/Right and Front/Rear are determined as if viewed from the driver's seating position.

A P0014 DTC trouble code may be caused by one or more of the following: Incorrect camshaft timing , Wiring problems (harness/wiring) in intake timing control valve control solenoid system , Continuous oil flow to VCT piston chamber, Failed timing valve control solenoid (stuck open)

2006 Pontiac G6 | G6 (VIN Z) Service Manual | Document ID: 1617665 -------------------------------------------------------------------------------- DTC P0010, P0011, P0013, or P0014 Diagnostic Instructions • Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. • Review Strategy Based Diagnosis for an overview of the diagnostic approach. • Diagnostic Procedure Instructions provides an overview of each diagnostic category. DTC Descriptors DTC P0010: Intake Camshaft Position (CMP) Actuator Solenoid Control Circuit DTC P0011: Intake Camshaft Position (CMP) System Performance DTC P0013: Exhaust Camshaft Position (CMP) Actuator Solenoid Control Circuit DTC P0014: Exhaust Camshaft Position (CMP) System Performance Diagnostic Fault Information Circuit Short to Ground High Resistance Open Short to Voltage Signal Performance Intake CMP Actuator Solenoid Control P0010 P0010 P0010 P0010 P0011 Intake CMP Actuator Low Reference -- P0010 P0010 -- -- Exhaust CMP Actuator Solenoid Control P0013 P0013 P0013 P0013 P0014 Exhaust CMP Actuator Low Reference -- P0013 P0013 -- -- Circuit/System 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. Conditions for Running the DTC P0010 and P0013 The engine is running. P0011 and P0014 • The engine speed is more than 1,350 RPM. • The engine control module (ECM) has enabled the CMP actuator. • The system voltage is more than 11 volts. • DTC P0011 and P0014 run continuously when the above conditions are met. Conditions for Setting the DTC P0010 and P0013 The ECM detects an open, short to ground, or a short to voltage on the high control circuit or an open on the low reference circuit for more than 0.25 second. P0011 and P0014 • The control module has enabled the CMP actuator. • The difference between the desired CMP actuator angle and the actual CMP actuator angle is more than 6 degrees. • The CMP actuator is steady for 3 seconds. • The condition is present for 13.5 seconds. Action Taken When the DTC Sets DTCs P0010, P0011, P0013 and P0014 are Type B DTCs. Conditions for Clearing the MIL/DTC DTCs P0010, P0011, P0013 and P0014 are Type B DTCs.

Observe the engine oil level. The engine oil level should be within the operating range. Allow the engine to reach operating temperature. Increase the engine speed to 1,500 RPM. Command each CMP actuator to 25 percent. The CMP actuator angle desired parameter should match the CMP actuator actual parameter. Circuit/System Testing With the ignition ON, measure for battery voltage between the CMP actuator solenoid control of the affected actuator and a ground. ⇒ If less than battery voltage, test the CMP actuator control circuit for an open, short to ground. If the circuit tests normal, replace the control module. Connect a test lamp between the CMP actuator solenoid control of the affected actuator and a good ground. The test lamp should not illuminate. ⇒ If the test lamp illuminates, test the CMP actuator control circuit for a short to voltage. If the circuit tests normal, replace the control module. Command each CMP actuator solenoid between 0-50 percent. The test lamp should turn ON and OFF. ⇒ If the test lamp does not turn ON and OFF, test the CMP actuator control circuit for high resistance. If the circuit tests normal, replace the control module. Connect a test lamp between the low reference circuit of the CMP actuator solenoid of the affected actuator and battery voltage. The test lamp should illuminate. ⇒ If the test lamp does not illuminate, test the low reference circuit for an open, high resistance. If the circuit tests normal, replace the control module. Determine that the vehicle has the correct engine oil. Refer to Service and Appearance Care in the owner's manual. ⇒ If the engine oil life system monitor displays the Change Oil Soon message, the engine oil is more than one year old, contains additives, or is not the correct viscosity, change the oil. Test the engine oil pressure. Refer to Oil Pressure Diagnosis and Testing . ⇒ If the oil pressure is low, correct the low pressure first. Inspect each CMP actuator solenoid valve assembly for the following: • Torn screens • Debris on the screens • Debris clogging the oil ports • Missing screens • Oil seepage at the solenoid connector pins Inspect for the following conditions: • Excessive timing chain play • Proper installation of the CMP actuator assembly Component Testing Measure the resistance of each CMP actuator solenoid valve assembly. Resistance should be between 8-12 ohms. Connect a jumper wire between the CMP actuator low reference circuit at the solenoid and a good ground. Connect a fused jumper wire to the CMP actuator high control circuit at the solenoid. Momentarily touch the fused jumper to B+. Observe the spool valve inside the CMP actuator. The spool valve should move from fully closed to fully opened position. Repair Instructions Perform the Diagnostic Repair Verification after completing the diagnostic procedure. • Camshaft Position Actuator Solenoid Valve Replacement • Control Module References for replacement, setup, and programming. © 2011 General Motors Corporation.
