The P1360 diagnostic trouble code is a manufacturer-specific powertrain code. Its exact definition depends heavily on the vehicle make, pointing to an ignition control circuit, a camshaft actuator, or a stop-start battery fault.
Because this code targets different systems across manufacturers, the exact vehicle application must be verified before diagnosis. The code alone does not prove a specific component has failed without proper testing.
Quick Navigation
Key Takeaways
- P1360 is a manufacturer-specific powertrain code with differing definitions depending on the vehicle make.
- On GM and Honda applications, it indicates an Ignition Control Circuit Group 2 or Ignition Coil Group 2 fault.
- On Toyota and Lexus applications, it points to an ‘A’ Camshaft Position Actuator Circuit fault on Bank 1.
- On certain Suzuki applications, it indicates a stop-start system battery performance issue.
- Diagnosis requires verifying the exact factory definition and testing the relevant ignition, camshaft, or battery system.
P1360 Code Description and Implications
The P1360 code indicates that a control module has detected a specific fault within the ignition, valve timing, or starting systems. Because it is a manufacturer-specific code, the exact monitored component varies significantly by brand.
Some GM, Cadillac, and Honda applications: P1360 indicates an Ignition Control Circuit Group 2 or Ignition Coil Group 2 Control Circuit fault. The PCM detects an electrical issue in the control circuit for the second group of ignition coils.
Certain Toyota and Lexus applications: The code indicates an ‘A’ Camshaft Position Actuator Circuit Open, Low, or High fault on Bank 1. The ECM detects an electrical issue in the variable valve timing actuator motor circuit.
Some Suzuki and Maruti applications: P1360 indicates an Engine Auto-Stop Battery Performance fault. The control module detects that the dedicated stop-start system battery is failing to hold an adequate charge or perform correctly.
Common Causes of the P1360 Code
Because P1360 applies to different systems across different brands, the root cause depends on the verified vehicle application.
GM and Honda Causes: A failed ignition coil in group 2, damaged wiring or poor electrical connections at the coil or PCM, or a faulty ignition control module.
Toyota and Lexus Causes: A failed camshaft timing control motor, damaged wiring harness, poor electrical connections, or an internal ECM driver issue affecting the actuator circuit.
Suzuki Causes: A degraded stop-start system battery, poor battery terminal connections, or a failing battery management system sensor.
Symptoms Associated With P1360
When the control module detects a critical ignition, timing, or starting system fault, it illuminates a warning light and may alter engine operation.
Warning Lights: The Check Engine Light will illuminate. On Suzuki applications, an Auto-Stop system warning or battery light may also appear.
Drivability: On GM and Honda applications, engine misfires, rough idling, or a failure to start may occur. On Toyota applications, the engine may enter a fail-safe mode with reduced power. On Suzuki applications, the stop-start system will disable itself.
Diagnosing the P1360 Trouble Code
Accurate diagnosis begins by verifying the exact vehicle application and reviewing manufacturer-specific service information.
For GM and Honda applications: Inspect the wiring harness and connectors for the group 2 ignition coils. Test the coil resistance and verify the control signal from the PCM using a multimeter or oscilloscope.
For Toyota and Lexus applications: Inspect the wiring harness for the camshaft timing control motor. Verify power and ground at the actuator connector. Test the motor resistance and check for mechanical binding in the valve timing system.
For Suzuki applications: Test the stop-start system battery voltage and health. Inspect the battery terminals and the battery management system sensor for proper connection and operation.
Repairing the P1360 Issue
Repairs must follow the confirmed root cause identified during diagnosis.
Ignition Component Repairs: If an ignition coil or control module fails testing, replace the confirmed failed component. Repair any damaged wiring or corroded connectors in the ignition circuit.
Camshaft Actuator Repairs: If the camshaft timing control motor fails electrical testing, replace the actuator. Repair any damaged wiring in the actuator circuit and verify proper valve timing operation.
Battery System Repairs: If the stop-start battery fails a load test, replace the battery and perform the required battery management system reset procedure.
Cost Considerations for P1360 Repairs
Cost depends on diagnostic time, component accessibility, required parts, programming requirements, and labor.
Replacing an external ignition coil or stop-start battery involves minimal to moderate labor. However, replacing a camshaft timing actuator or tracking down an intermittent wiring fault requires additional diagnostic and labor time.
Prevention Strategies for Future Occurrences
Ensuring ignition coils and electrical connectors are kept clean and secure helps prevent moisture intrusion and poor electrical connections.
Replacing the stop-start system battery at the manufacturer’s recommended intervals helps prevent unexpected battery performance faults in mild-hybrid or auto-stop equipped vehicles.
Troubleshooting Tips and Best Practices
Follow these practices to avoid misdiagnosis and ensure accurate repairs.
Do not assume the ignition coil is dead on GM applications: A broken wire or corroded connector in the control circuit is a frequent cause of the fault. Always verify the control signal before replacing the coil.
Check for related codes: Look for accompanying misfire codes like P0300 or camshaft timing codes like P0011, which might help pinpoint a broader wiring harness or mechanical issue.
Verify your definition: When researching this fault code, always confirm whether your specific vehicle uses the ignition, camshaft, or battery definition before ordering parts.

Frequently Asked Questions
Is P1360 a generic or manufacturer-specific code?
No. P1360 is a manufacturer-specific powertrain code. Its definition varies significantly by brand, indicating an ignition circuit fault, a camshaft actuator issue, or a stop-start battery fault.
Can I drive my vehicle with a P1360 code?
The vehicle may remain drivable, but a severe ignition or camshaft actuator fault can cause misfires, rough idling, or reduced power. Stop-start systems will simply disable themselves.
Will disconnecting the battery clear the P1360 code?
Disconnecting the battery might temporarily clear the code. However, it does not repair the underlying failed coil, damaged wiring, or degraded stop-start battery, and the code will return.
Can a bad stop-start battery cause a P1360 code?
Yes. On Suzuki and Maruti applications where P1360 indicates an auto-stop battery performance fault, a degraded dedicated battery is the primary cause of the code.
Does P1360 affect the transmission?
No. The P1360 code relates strictly to the engine ignition system, camshaft timing actuator, or stop-start battery. It does not directly affect the automatic or manual transmission.
What Should You Do About the P1360 Code?
When a P1360 code appears, confirm the exact factory definition for your specific vehicle make and model. Because this code targets entirely different ignition, timing, and battery systems depending on the manufacturer, applying the wrong diagnostic path will lead to misdiagnosis.
Follow the applicable manufacturer diagnostic procedure to test the relevant system and components. Once the root cause is confirmed, complete the necessary electrical repairs, actuator replacements, or battery corrections before returning the vehicle to normal service.
