Meaning of Mazda P1360 Code
This code indicates a malfunction in the secondary circuit of ignition coil “A”.
- Coil “A” = Usually the coil for cylinder #1 (check vehicle manual).
- Secondary circuit = High voltage part of the coil (which powers the spark plug).
⚠️ Note: The exact definition may vary depending on your Mazda’s model and year.
Possible Symptoms
- 🚨 Check Engine light on
- 🔥 Misfires (especially on the affected cylinder)
- 🏎️ Loss of power / Hesitant acceleration
- 🔊 Engine coughing or vibrating
Probable Causes
- Faulty ignition coil “A” (the most common cause)
- Wiring problem (cut wires, short circuit, damaged connector)
- Poor electrical connection (corrosion, bent pins)
- Worn or faulty spark plug (can damage the coil)
- PCM problem (rare, but possible if the control circuit is failing)
Diagnosis and Repair
1. Visual Inspection
- Check coil “A” (usually cylinder 1) and its connector.
- Look for damaged wires (chafed, burnt, or exposed).
- Clean oxidized connectors (use electrical contact cleaner).
2. Ignition Coil Test
✅ Method 1: Coil Swap
- Move coil “A” to another cylinder.
- If the code follows the coil → It is faulty.
✅ Method 2: Resistance Measurement
- Check primary/secondary resistance (according to manufacturer specifications).
- A resistance out of specification = Faulty coil.
3. Spark Plug Check
- Remove the spark plug from the affected cylinder and inspect:
- Worn electrode?
- Correct gap?
- Cracked insulation?
- If in doubt, replace the spark plug.
4. Electrical Circuit Test
- Multimeter required:
- Check for 12V power at the coil connector (ignition ON).
- Test the ground and the PCM signal.
- If the circuit is OK but the problem persists → PCM potentially faulty.
Recommended Repairs
✅ Replace faulty ignition coil “A”
✅ Repair damaged wiring (solder + heat shrink tubing)
✅ Clean/replace corroded connectors
✅ Change worn spark plug
✅ Update PCM (if necessary)
Practical Tips
🔧 Useful tools:
- OBD2 scanner (to clear codes)
- Multimeter (for electrical tests)
- Spark plug socket (for inspection)
⚠️ Precautions:
- Disconnect the battery before working on the circuit.
- Cold engine to avoid burns.
🚗 Note:
- A faulty coil can damage the catalytic converter if not repaired quickly.
Conclusion
The Mazda P1360 code indicates a problem in the secondary circuit of coil “A”.
🔹 Start by checking the coil and its wiring.
🔹 Test the spark plugs and electrical supply.
🔹 If everything seems good, consider a PCM issue.
