Code P2319 2016 GMC Sierra Description

The ignition system on this engine uses ignition coils with integrated power transistors. The Engine Control Module (ECM) controls the spark event for each cylinder through individual ignition coil control circuits. When the ECM commands the ignition control circuit On, electrical current flows through the primary winding of the ignition coil, creating a magnetic field. When a spark event is requested, the ECM commands the ignition control circuit Off, interrupting current flow through the primary winding. The collapsing magnetic field created by the primary winding induces a high voltage in the secondary winding, which is connected to the spark plugs. The Diagnostic Trouble Code (DTC) will be set when the control circuit commanded by the ECM state does not match the actual state.

P2319 indicates a high voltage issue in the control circuit for ignition coil 7, which could impact the functionality of that specific coil.

2. What are the symptoms of code P2319 on a 2016 GMC Sierra?

Common symptoms include engine misfires, rough idling, reduced performance, poor fuel economy, and the check engine light being illuminated.

3. What causes the P2319 code to appear on a 2016 GMC Sierra?

Possible causes include a faulty ignition coil 7, damaged wiring or connectors in the coil's circuit, a defective ignition control module, or an issue with the PCM.

4. Can you drive a 2016 GMC Sierra with the P2319 code?

While the vehicle may still be drivable, driving with this code can cause further engine damage or poor performance. Itâ€™s best to address the issue promptly.

5. How do you diagnose the P2319 code on a 2016 GMC Sierra?

Diagnosis typically includes scanning for stored codes, inspecting ignition coil 7 and its wiring for damage, and testing the coil and control circuit for proper voltage and continuity.

6. How can you fix the P2319 code on a 2016 GMC Sierra?

Repairs may include replacing the ignition coil 7, repairing or replacing damaged wiring or connectors, or reprogramming or replacing the PCM if necessary.

7. What tools are needed to diagnose the P2319 code on a 2016 GMC Sierra?

Youâ€™ll need an OBDII scanner, a multimeter to test voltage and continuity, and possibly a wiring diagram for the ignition system.

8. How much does it cost to fix the P2319 code on a 2016 GMC Sierra?

The cost varies depending on the exact issue, but ignition coil replacement typically costs $50-$150 for the part, plus labor if done by a mechanic.

9. Can a bad spark plug cause the P2319 code on a 2016 GMC Sierra?

While a bad spark plug itself wonâ€™t trigger P2319, it can cause similar symptoms. Itâ€™s important to check the spark plug when diagnosing ignition coil issues.

10. Does the P2319 code require reprogramming the PCM on a 2016 GMC Sierra?

Reprogramming the PCM is not usually required unless itâ€™s determined to be faulty or a software update is necessary to resolve the issue.
