Hi help pls I have this dtc:P0698 description (failure of wiring and connection. failure of spark plug control module) engin no start
My car has an automatic transmission.
Hi there. Typically this is a failure in the ignition control circuit. Most of the time it is a wiring failure going to the ignition coils such as a bad ground connection. It can also be caused by a failure in the main computer which happens most of the time on this vehicle.
I usually start by checking the circuit for power to eliminate a blown fuse or ignition switch issue. If no problems are found there then I move on to testing the wiring and the computer to see which one the vehicle needs.
