P1361 – OBD-II DTC

OBD-II DTC P1361 – Ignition Coil A Primary Circuit Malfunction

DTC P1361 meaning

DTC P1361 refers to a malfunction in the primary circuit of Ignition Coil A. This code indicates that the Engine Control Module (ECM) has detected an issue with the electrical circuit that powers the ignition coil responsible for firing the engine’s cylinders. The ignition coil converts the battery’s low voltage to the high voltage needed to create a spark at the spark plugs, which is essential for engine combustion.

Common symptoms associated with DTC P1361 may include:

• Engine misfires
• Rough idling
• Decreased engine performance
• Difficulty starting the engine
• Illuminated check engine light

DTC P1361 causes

Several factors can lead to the triggering of DTC P1361, including:

• Faulty ignition coil A
• Open or shorted wiring in the ignition coil circuit
• Defective ignition control module
• Corroded or loose electrical connectors
• Faulty ECM

DTC P1361 seriousness

The seriousness of DTC P1361 can vary. While it may not cause immediate catastrophic failure, it can lead to:

• Increased emissions
• Reduced fuel efficiency
• Potential engine damage if misfires persist
• Inability to pass emissions tests

It is advisable to address this code promptly to avoid further complications.

How to diagnose DTC P1361

To diagnose DTC P1361, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the P1361 code.
