ECM 3501
The control module reports the fixing of misfires in the first cylinder of the engine.
Possible causes of the problem:
- malfunction of the spark plug: damage to its contact or the formation of soot on the device;
- failure of the switchgear, the appearance of cracks in its housing;
- poor compression in the cylinders of the power unit;
- lack of balance in the formation of the air-fuel mixture, in particular, lack of fuel;
- malfunction of one or more fuel injectors.
ECM 3502
Misfire in the second cylinder of the engine
P0300 (ECM 3503)
Misfire in the third cylinder of the power unit
ECM 3504
Misfire in the fourth engine cylinder
ECM 6140
Malfunctions of the camshaft adjustment system
P2089 (ECM 6400)
Intake camshaft recovery valve is not working properly or is turned off
P0011 (ECM 640 A)
Error camshaft position of the car.
Possible causes of the malfunction:
- malfunctioning CVVT phase distribution system;
- malfunctions recorded in the functioning of the camshaft gear;
- violation of the flow of motor fluid into the piston chamber VCT;
- damage to the wiring or contact elements on the connection block of the gas distribution system;
- VVT-i valve sensor breakdown due to clogging or when replacing the timing chain.
