P1315: Understanding The Causes And Solutions For This Automobile Fault Code
The P1315 fault code refers to an issue with the igniter circuit for cylinder number 4 in the Direct Ignition System (DIS). This system is responsible for igniting each cylinder individually using one ignition coil per cylinder.
The ignitor is built into the ignition coil itself. The Engine Control Module (ECM) controls the ignition timing and sends an ignition signal (IGT) to each cylinder.
This signal is used by power transistors in the ignitor to cut off the current to the primary coil in the ignition coil, causing it to fire the spark plug. The P1315 code indicates a malfunction in the igniter circuit for cylinder number 4.
This means that there is an issue with the circuit that controls the ignition for this specific cylinder. The ECM monitors the IGF circuit to ensure that the primary switching occurred properly after sending the command to turn off the primary circuit on the IGT wire.
FAQ
If you’re seeing the engine light on or the service engine soon warning light in your automobile, it could be due to fault code P1315. This code is often caused by a faulty ignition coil No. 4, an open or shorted harness for the ignition coil No. 4, a poor electrical connection in the ignition coil No. 4 circuit, or a faulty engine control module (ECM). To fix this issue, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins in the connectors.
If you’re dealing with fault code P1315 and your engine light is on, it’s time to take action. The most common causes for this code are a faulty ignition coil, an open or shorted ignition coil harness, a poor electrical connection in the ignition coil circuit, or a faulty engine control module. To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken or bent pins, corrosion, or components that are out of place. Don’t delay – get to the bottom of this problem and get your engine running smoothly again.
When resolving fault code P1315, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. These issues can cause a poor electrical connection or an open or shorted circuit, leading to the engine light being on. By checking and addressing these possible causes, you can effectively resolve the P1315 fault code.
Wrap Up
