P1360 · VolkswagenCylinder 2 Ignition Circuit Short To Ground

P1360 on Volkswagen vehicles means the engine control module (ECM) has detected an abnormally low voltage or a direct short to ground on the ignition coil control circuit for cylinder 2. The ECM commands a spark event by pulling the coil primary circuit to ground, and it monitors the resulting current and voltage signature; when the circuit stays grounded longer than expected or the feedback voltage is near zero, this code is stored.

Symptoms you may notice

  • Check engine light illuminated, often with no other noticeable symptoms
  • Rough idle or misfire felt as a shake or stumble, especially when cold
  • Noticeable loss of power and poor acceleration under load
  • Increased fuel consumption due to incomplete combustion in cylinder 2
  • Occasional flashing check engine light if the misfire becomes severe enough to damage the catalytic converter
  • Hard starting or stalling in more advanced cases where the short affects shared ignition power

Common causes, most likely first

  1. Ignition coil for cylinder 2 internally shorted to ground
  2. Chafed or pinched wire in the cylinder 2 coil control circuit contacting engine metal
  3. Corroded, loose, or backed-out terminal at the cylinder 2 coil connector
  4. Faulty engine control module (ECM) driver for the cylinder 2 ignition circuit
  5. Aftermarket alarm or remote start wiring tapped into the ignition harness and shorting
  6. Oil or coolant contamination in the coil connector causing a conductive path to ground
  7. Damaged ignition harness section near the cylinder head or intake manifold where heat and vibration are high

How to diagnose and fix it

  1. Scan all modules and record freeze-frame data to confirm the fault is active and not a stored history code from a past repair
  2. Inspect the cylinder 2 ignition coil connector and harness for corrosion, chafing, or oil intrusion, and repair terminals or replace damaged wire sections
  3. Swap the cylinder 2 ignition coil with another cylinder and clear the code to see if the fault moves, which isolates a bad coil
  4. Measure resistance from the cylinder 2 coil control wire to ground with the ECM disconnected; a reading near zero ohms confirms a short to ground in the harness
  5. Check the ignition coil power supply and ground circuits for voltage drop under load, since a weak ground can mimic a short
  6. If the harness and coil test good, perform an ECM driver test with a breakout box or oscilloscope to verify the ECM is not holding the circuit low internally
  7. Replace the faulty ignition coil or repair the harness, clear the code, and road-test the vehicle through several drive cycles to confirm the repair

What a shorted coil driver really means

  • A P1360 can be set by a coil that tests fine with a multimeter but breaks down internally only when hot, so a cold resistance check alone is not conclusive.
  • Volkswagen ignition coils on the 1.8T and 2.0T engines are known for internal shorting that sets cylinder-specific codes, and swapping coils between cylinders is the fastest way to confirm the fault.
  • The ECM driver for the ignition circuit can fail after a coil shorts, so replacing only the coil without checking the control wire can lead to a repeat failure.
  • Aftermarket wiring for alarms or remote starters tapped into the coil harness is a common hidden cause of a short to ground that does not appear in factory service information.
  • A P1360 does not always mean the coil is bad; a shorted wire rubbing on the engine lifting eye or intake bracket can set the same code with a perfectly good coil.

Can I keep driving with P1360?

You can drive the vehicle short distances to a repair shop, but avoid heavy acceleration and long trips because a persistent misfire on cylinder 2 can overheat and damage the catalytic converter. If the check engine light is flashing, stop driving and have the vehicle towed.
