Ignition

Problems such as no spark in the spark plug, no ignition pulse are related to this component, if the defect is found, replace it.

Problems such as lack of mass in the sensors are caused by the compromise of the sensors' mass track, perform a “jumper” from Pin 05, to Pin 01, which is the ECU's Mass, Use medium gauge wire.


MAP or TPS

Problems linked to the power supply of these two components of the vehicle, check the pin that is receiving the 5V (+) power supply, check the track that this power is not reaching, as soon as the defect is found, make a jumper on the track Also good for the pin that stopped receiving 5V power.


E-Prom

E-prom memory error, or vehicle from time to time to complete, due to poor contact in the E-prom PLCC socket, which is located between the 2 processors, problems can happen, more likely in sockets that are not original from the factory, if this problem occurs, remove the socket and solder the component directly to the board.
