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

1. Faulty ignition coil “A” (the most common cause)
2. Wiring problem (cut wires, short circuit, damaged connector)
3. Poor electrical connection (corrosion, bent pins)
4. Worn or faulty spark plug (can damage the coil)
5. 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.

Possible Symptoms

• Check Engine Light on (or Service Engine Soon Warning Light)

Possible Causes

NOTE: The listed causes may not be a complete list of all potential problems and there may be other causes.

• Faulty cylinder 2 ignition coil
• Cylinder 2 ignition coil harness is open or shorted
• Poor electrical connection in cylinder 2 ignition coil circuit
• Faulty Engine Control Module (ECM)

Description

The Engine Control Module (ECM) must determine if a misfire is occurring and identify the specific cylinder(s) and severity of the misfire event and whether it is relevant for emissions or damaging to the catalyst. To accomplish these tasks, the control module monitors the crankshaft for acceleration losses during the firing segments of each cylinder according to the firing order.
The misfire/engine roughness calculation is derived from the differences in period duration (T) of individual increment gear segments. Each segment period consists of an angular range of 120° of crankshaft angle starting 78° before Top Dead Center (TDC).
If the expected period duration is greater than the allowed value, a misfire fault for the particular cylinder is recorded in the ECM’s fault memory. Depending on the measured misfire rate level, the control unit illuminates the “Service Engine Soon” light, may cut fuel to the particular cylinder, and may switch lambda operation to open loop. All misfire faults are weighted to determine whether the misfire is relevant for emissions or damaging to the catalyst.

How to Repair

Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

• Engine Light On (or Service Engine Soon Warning Light)

Possible Causes

NOTE: The listed causes may not be a complete list of all potential issues and there may be other causes.

• Faulty Top Dead Center sensor 1 (inside the distributor)
• Top Dead Center sensor 1 harness is open or short-circuited
• Poor electrical connection of Top Dead Center sensor circuit 1

Description

The Crankshaft Position Sensor (CKP) determines the timing of fuel injection and ignition for each cylinder and also detects engine speed. The Top Dead Center (TDC) sensor determines ignition timing during startup (cranking) and when the crankshaft angle is abnormal. The Cylinder Position (CYP) sensor detects the position of cylinder #1 for sequential fuel injection in each cylinder. The CKP/TDC/CYP sensors are integrated into the distributor. If intermittent pulse signals from the Top Dead Center (TDC) sensor are detected, a malfunction is identified and Diagnostic Trouble Code (DTC) P1382 is stored.
