P1362 · JaguarIgnition Coil Cylinder 2 No Activation

Q: What does code P1362 mean?

Ignition Coil Cylinder 2 No Activation. P1362 on a Jaguar means the engine control module (ECM) commanded the ignition coil for cylinder 2 to fire but detected no electrical activation or feedback from that coil circuit. The ECM monitors the coil primary circuit and flags this code when the expected current pulse or confirmation signal is missing, indicating an open circuit, short, or failed coil.

AreaIgnition system and misfire

Symptoms you may notice

Engine misfire felt as a stumble or shake, especially under acceleration or load
Rough idle with noticeable vibration through the steering wheel or seat
Reduced engine power and poor throttle response
Check engine light illuminated, sometimes flashing if the misfire is severe
Often no symptoms besides the warning light when the fault is intermittent or only occurs under specific conditions
Slightly higher fuel consumption due to incomplete combustion in cylinder 2

Common causes, most likely first

Faulty ignition coil on cylinder 2 (open or shorted primary winding)
Damaged or corroded electrical connector at the cylinder 2 coil
Broken, chafed, or open wire in the coil activation circuit between the ECM and coil
Poor ground connection for the ignition coil circuit
Failed ignition coil driver inside the ECM (less common but possible)
Contamination or oil ingress into the coil connector or spark plug well

How to diagnose and fix it

Scan all modules for stored codes and record freeze-frame data to confirm the fault conditions
Visually inspect the cylinder 2 ignition coil, connector, and wiring for damage, corrosion, or oil contamination
Swap the cylinder 2 ignition coil with a known-good coil from another cylinder and clear the code to see if the misfire moves
Measure resistance of the cylinder 2 coil primary and secondary windings and compare with the manufacturer's specification
Check for battery voltage at the coil connector with the ignition on and inspect the ground circuit for continuity
Perform a wiggle test on the coil wiring harness while monitoring misfire counters or the code status
If wiring and coil test good, check the ECM activation signal with an oscilloscope or a noid light before condemning the ECM

Why cylinder 2 coil codes often mislead

A P1362 can be set by a faulty spark plug or excessively large plug gap that overloads the coil, so always inspect the plug before replacing the coil.
Oil leaking into the spark plug well from a failed cam cover gasket is a common Jaguar issue that damages the coil and sets this code, and it will ruin a new coil if not fixed.
The ECM may set P1362 intermittently due to a loose connector pin that only loses contact when the engine moves under torque, so a static resistance check can pass while the fault remains.
Swapping coils to see if the misfire follows the coil is the fastest way to rule out the coil itself, but you must clear the code and recheck because the ECM may not immediately re-enable the circuit.
A P1362 does not always mean the coil is dead; a shorted or open activation wire between the ECM and coil can produce the same no-activation signal, so circuit testing is essential.

Can I keep driving with P1362?

You can drive a short distance to a repair shop if the misfire is mild and the check engine light is steady, but avoid hard acceleration and heavy loads. If the light flashes or the engine runs very rough, stop driving to prevent unburned fuel from damaging the catalytic converter.
