Nissan Cube C1206 Engine Trouble Code
What is Nissan Cube C1206?
The Nissan Cube C1206 check-engine light can indicate issues ranging from minor (loose gas cap) to serious (catalytic converter failure). Professional diagnostic scanning at a dealer or shop will identify the exact cause and required repairs.
C1206 on the Nissan Cube
Nissan Cube models produced in the mid-cycle refresh years show a statistical uptick in C1206 occurrences linked to the variable valve timing (VVT) actuator. A sludge deposit in the oil galleries feeding the actuator is the leading suspect.

How to Fix Nissan Cube C1206
Diagnostic Steps:
Check if fuel pump primes when key is turned to ON. Measure fuel pressure and verify bright white-blue spark at all plugs. Also verify mechanical timing alignment.
Repair Solution:
Disconnected, dirty, or fouled spark plugs commonly prevent proper engine operation. Replace spark plugs every season or 25 hours. Verify proper spark plug gap. If plugs are good, check ignition components: spark plug wires, coils, and ignition module.
Technical Notes:
Parts or components should not be replaced based solely on C1206 DTC. Consult your vehicle service manual for proper diagnostic procedures, possible causes, and required testing before replacement.

C1206 Description
C1206 engine trouble code is related to Ignition Coil A Primary/Secondary Circuit Malfunction.
Main Cause
The primary reason for C1206 OBD-II Engine Trouble Code is: Manifold Absolute Pressure/Barometric Pressure Circuit High Input.
Common C1206 Misdiagnosis on the Nissan Cube
On the Nissan Cube, the VANOS (variable camshaft timing) solenoid is routinely replaced for C1206 when the actual issue is oil pressure insufficiency. No solenoid will operate correctly if the oil pressure required to actuate the VVT phaser is not present.
DIY Repair Guide: C1206 on Nissan Cube
The coolant temperature sensor on the Nissan Cube is a straightforward DIY item (difficulty 2/5). Have a drain tray ready for the small amount of coolant that spills when the sensor is removed. Top up the cooling system afterwards and check for air pockets.
Preventing C1206 on the Nissan Cube
Scheduled inspection of the Nissan Cube air filter every 15,000 miles can prevent the intake restriction that leads to C1206. A blocked filter forces the engine to run rich, stressing the catalytic converter and ultimately storing fault codes.
Frequently Asked Questions — Nissan Cube C1206
A: It depends on the severity. If the check-engine light is steady, it is generally safe to drive to a workshop within the next few days. If the light is flashing, pull over safely as soon as possible — a flashing light indicates an active misfire that can cause expensive catalytic converter damage within minutes.
